Colmi P78 Smartwatch Review: A Feature-Packed Budget Wearable Worth Considering
Colmi has built a strong reputation among budget-conscious smartwatch users, offering affordable yet feature-rich devices. The popular Chinese brand recently introduced its latest model, the Colmi P78, in Bangladesh, aiming to attract wearable tech enthusiasts with a balance of functionality and affordability. In this review, we’ll explore its key features, ideal users, and whether it’s worth your money.
Key Specifications of the Colmi P78 Smartwatch
The Colmi P78 is a fine overhaul of its predecessor. It boasts a more polished design, a larger screen, and additional features contributing to a better experience.
Design
The design features a round-cornered, rectangular mainframe containing about a 2-inch display. Colmi has coined the term “bowl-shaped,” referring to the watch’s spherically curved sides. Beyond its larger body, the Colmi P78 differs from its predecessor in many ways, including featuring slimmer bezels and incorporating a side-mounted flashlight.

Though the entire body is plastic-made, all seams and engravings manifest delicate finishing and IP67 water resistance. With a 10.7mm thickness and 30g of weight, the watch meets the mass demand for a slim and lightweight design.
On the upper right side sits a knurled crown with added functionalities to sweep through different on-display options. For every unit of rotation, the crown makes a clicking sound, allowing blind navigation. The knurls give a better grip, even for wet hands. The watch provides four distinct colour variations– black, silver, pink, and gold.
Display
The Colmi P78 ships with a 1.95-inch AMOLED screen, an appreciable leap from the previous model’s LCD panel. Also, a wider 410 by 502 resolution renders sharper visuals on the screen. However, due to a lower refresh rate, the navigation across the board lacks the smooth haptic feedback of higher touch-responsive displays. Unlike many budget-friendly options, the display supports always-on-display screensavers.

Workday lays off 1,750 employees, or about 8.5% of its workforce
Workday is cutting about 1,750 jobs, or 8.5% of its workforce.
In a Wednesday memo to employees, published in a securities filing, Workday CEO Carl Eschenbach said the layoffs were necessary for ongoing growth efforts at the company — including a particular focus on artificial intelligence investments.
“As we start our new fiscal year, we’re at a pivotal moment,” Eschenbach wrote. “Companies everywhere are reimagining how work gets done, and the increasing demand for AI has the potential to drive a new era of growth for Workday.”
Workday aims to notify the majority of employees affected by the cuts on Wednesday. “I realize this is tough news, and it affects all of us,” Eschenbach added — encouraging employees to work from or head home for the day.
Researchers link China's DeepSeek chatbot to a state telecom, raising privacy concerns
The maker of human resources software also disclosed that it expects to exit certain office space, but didn't specify a timeline or which locations may be impacted. Still, Eschenbach's memo notes that the restructuring will work to expand Workday's global reach by “investing in strategic locations.”
And despite the current layoffs, the maker of human resources software says that it still expects to continue hiring in certain locations and positions over the next year.
Workday estimates that it will incur between $230 million and $270 million in charges related to the restructuring plan — primarily in severance payments, employee benefits and other related costs. All employees laid off in the U.S. will be offered a minimum of 12 weeks of pay, with additional weeks based on tenure, Eschenbach said Wednesday, adding that affected workers in other countries will be offered packages based on local standards.
The job cuts at Workday arrive as layoffs continue across the tech sector — including from big names like Intel, Cisco and Apple over the past year — amid a broader wave of industry consolidation. Many companies have turned to restructuring as they grapple with how to stay competitive with evolving consumer spending, while also boosting AI-related investments.
Workday plans to release earnings results for its full 2025 fiscal year later this month. In the third quarter, the Pleasanton, California-based company posted a net income of $193 million and revenue of $2.16 billion — up from a net income of $132 million and revenue of $2.09 billion in the period prior.
Shares for Workday were up more than 2.5% by midday trading Wednesday.

Researchers link China's DeepSeek chatbot to a state telecom, raising privacy concerns
The website of the Chinese artificial intelligence company DeepSeek, whose chatbot became the most downloaded app in the United States, has computer code that could send some user login information to a Chinese state-owned telecommunications company that has been barred from operating in the United States, security researchers say.
The web login page of DeepSeek’s chatbot contains heavily obfuscated computer script that when deciphered shows connections to computer infrastructure owned by China Mobile, a state-owned telecommunications company. The code appears to be part of the account creation and user login process for DeepSeek.
In its privacy policy, DeepSeek acknowledged storing data on servers inside the People’s Republic of China. But its chatbot appears more directly tied to the Chinese state than previously known through the link revealed by researchers to China Mobile. The U.S. has claimed there are close ties between China Mobile and the Chinese military as justification for placing limited sanctions on the company. DeepSeek and China Mobile did not respond to emails seeking comment.
The growth of Chinese-controlled digital services has become a major topic of concern for U.S. national security officials. Lawmakers in Congress last year on an overwhelmingly bipartisan basis voted to force the Chinese parent company of the popular video-sharing app TikTok to divest or face a nationwide ban though the app has since received a 75-day reprieve from President Donald Trump, who is hoping to work out a sale.
Italy blocks access to the Chinese AI application DeepSeek to protect users' data
The code linking DeepSeek to one of China’s leading mobile phone providers was first discovered by Feroot Security, a Canadian cybersecurity company, which shared its findings with The Associated Press. The AP took Feroot’s findings to a second set of computer experts, who independently confirmed that China Mobile code is present. Neither Feroot nor the other researchers observed data transferred to China Mobile when testing logins in North America, but they could not rule out that data for some users was being transferred to the Chinese telecom.
The analysis only applies to the web version of DeepSeek. They did not analyze the mobile version, which remains one of the most downloaded pieces of software on both the Apple and the Google app stores.
The U.S. Federal Communications Commission unanimously denied China Mobile authority to operate in the United States in 2019, citing “substantial” national security concerns about links between the company and the Chinese state. In 2021, the Biden administration also issued sanctions limiting the ability of Americans to invest in China Mobile after the Pentagon linked it to the Chinese military.
“It’s mindboggling that we are unknowingly allowing China to survey Americans and we’re doing nothing about it,” said Ivan Tsarynny, CEO of Feroot.
“It’s hard to believe that something like this was accidental. There are so many unusual things to this. You know that saying ‘Where there’s smoke, there’s fire’? In this instance, there’s a lot of smoke,” Tsarynny said.
Texas Governor orders ban on DeepSeek, RedNote for government devices
Stewart Baker, a Washington, D.C.-based lawyer and consultant who has previously served as a top official at the Department of Homeland Security and the National Security Agency, said DeepSeek “raises all of the TikTok concerns plus you’re talking about information that is highly likely to be of more national security and personal significance than anything people do on TikTok," one of the world’s most popular social media platforms.
Users are increasingly putting sensitive data into generative AI systems — everything from confidential business information to highly personal details about themselves. People are using generative AI systems for spell-checking, research and even highly personal queries and conversations. The data security risks of such technology are magnified when the platform is owned by a geopolitical adversary and could represent an intelligence goldmine for a country, experts warn.
“The implications of this are significantly larger because personal and proprietary information could be exposed. It’s like TikTok but at a much grander scale and with more precision. It’s not just sharing entertainment videos. It’s sharing queries and information that could include highly personal and sensitive business information,” said Tsarynny, of Feroot.
Feroot, which specializes in identifying threats on the web, identified computer code that is downloaded and triggered when a user logs into DeepSeek. According to the company’s analysis, the code appears to capture detailed information about the device a user logs in from — a process called fingerprinting. Such techniques are widely used by tech companies around the world for security, verification and ad targeting.
The company’s analysis of the code determined that there were links in that code pointing to China Mobile authentication and identity management computer systems, meaning it could be part of the login process for some users accessing DeepSeek.
Asian stocks rise as DeepSeek panic fades
The AP asked two academic cybersecurity experts — Joel Reardon of the University of Calgary and Serge Egelman of the University of California, Berkeley — to verify Feroot’s findings. In their independent analysis of the DeepSeek code, they confirmed there were links between the chatbot’s login system and China Mobile.
“It’s clear that China Mobile is somehow involved in registering for DeepSeek,” said Reardon. He didn’t see data being transferred in his testing but concluded that it is likely being activated for some users or in some login methods.

Judge says Elon Musk's claims of harm from OpenAI are a 'stretch' but welcomes possible trial
Elon Musk's lawyers faced off with OpenAI in court Tuesday as a federal judge weighed the billionaire's request for a court order that would block the ChatGPT maker from converting itself to a for-profit company.
U.S. District Judge Yvonne Gonzalez Rogers said it was a “stretch” for Musk to claim he will be irreparably harmed if she doesn't intervene to stop OpenAI from moving forward with its transition from a nonprofit research laboratory to a for-profit corporation.
But the judge also raised concerns about OpenAI and its relationship with business partner Microsoft and said she wouldn't stop the case from moving to trial as soon as next year so a jury can decide.
“It is plausible that what Mr. Musk is saying is true. We’ll find out. He’ll sit on the stand,” she said.
Musk, an early OpenAI investor and board member, sued the artificial intelligence company last year, first in a California state court and later in federal court, alleging it had betrayed its founding aims as a nonprofit research lab benefiting the public good. Musk had invested about $45 million in the startup from its founding until 2018, his lawyer said Tuesday.
Musk escalated the legal dispute late last year, adding new claims and defendants and asking for a court order that would stop OpenAI’s plans to convert itself into a for-profit business more fully. Musk also added his own AI company, xAI, as a plaintiff.
Also targeted by Musk's lawsuit is OpenAI's close business partner Microsoft and tech entrepreneur Reid Hoffman, a former OpenAI board member who also sits on Microsoft's board.
Gonzalez Rogers said she has a high bar for approving the kind of preliminary injunction that Musk wants but hasn't yet ruled on the request. She did say she had “significant concerns” with two people connected to Microsoft on OpenAI's board — Hoffman and longtime Microsoft executive Deanna Templeton, who was a “non-voting observer.”
“So you want me to believe that she was sitting there listening to all the discussions and not telling anybody? What would the point be for her to sit there and listen to everybody, if not to communicate what she was listening? There would be no point for her to be there, which is why she actually should not be there,” she said.
Hoffman, a co-founder of LinkedIn, has been on Microsoft’s board since shortly after the tech giant bought the job networking site. He stepped down from OpenAI's board in 2023 to avoid conflicts with his AI startup, Inflection.
Musk says USAID “criminal organisation, we’re shutting it down”
Templeton, who Musk also named as a defendant, was added as a non-voting member of OpenAI’s board in the aftermath of Altman’s ouster after Microsoft CEO Satya Nadella sought more stability on the board. But months later, she was dropped from the OpenAI board as U.S. antitrust enforcers were expressing concerns about such arrangements on corporate boards.
The judge has handled a number of tech industry cases including Apple's fight with Epic Games, though she said Tuesday that Musk's case is “nothing like” that one. That case was also the last time she granted a preliminary injunction, in 2020, eight months before the case went to trial.
Then-President Barack Obama appointed Gonzalez Rogers to the federal bench in 2011.
Tuesday's hearing was originally set for January but was postponed after Musk's attorney Marc Toberoff said his house was destroyed in the Pacific Palisades wildfire.
Musk, who did not attend the hearing, has alleged in the lawsuit that the companies are violating the terms of his foundational contributions to the charity. Judge Gonzalez Rogers called it a “stretch” to claim “irreparable harm” to Musk, and called the case “billionaires vs. billionaires.” She questioned why Musk invested tens of millions in OpenAI without a written contract. Toberoff said it was because the relationship between Altman and Musk at the time was “built on trust” and the two were very close.
“That is just a lot of money” to invest “on a handshake,” the judge said.
OpenAI has said Musk’s requested court order would “debilitate OpenAI’s business” and mission to the advantage of Musk and his own AI company and is based on “far-fetched” legal claims.
At the heart of the dispute is a 2017 internal power struggle at the fledgling startup that led to Altman becoming OpenAI’s CEO.
Emails disclosed by OpenAI show Musk had also sought to be CEO and grew frustrated after two other OpenAI co-founders said he would hold too much power as a major shareholder and chief executive if the startup succeeded in its goal to achieve better-than-human AI known as artificial general intelligence, or AGI. Musk has long voiced concerns about how advanced forms of AI could threaten humanity.
Altman eventually succeeded in becoming CEO and has remained so except for a period in 2023 when he was fired and then reinstated days later after the board that ousted him was replaced.

OpenAI has sought to demonstrate Musk’s early support for the idea of making OpenAI a for-profit business so it could raise money for the hardware and computer power that AI needs.
Musk is not the only one challenging OpenAI's for-profit transition. Facebook and Instagram parent Meta Platforms has asked California's attorney general to block it, and the office of Delaware's attorney general has said it is reviewing the conversion.
It was not clear Tuesday when the case might go to trial. Musk's lawyers initially said they would be ready by June after some back-and-forth with the two sides the judge indicated it probably won't be until June 2026 at the earliest, but likely early 2027.

Chinese scientists develop new AI model for cyclone forecast
Chinese scientists have developed a new artificial intelligence (AI) method to forecast the rapid intensification of a tropical cyclone, shedding new light on improving global disaster preparedness.
Recently, researchers from the Institute of Oceanology at the Chinese Academy of Sciences published this study in the journal, Proceedings of the National Academy of Sciences.
The rapid intensification of a tropical cyclone, which refers to a dramatic increase in the intensity of a tropical storm over a short period, remains one of the most challenging weather phenomena to forecast because of its unpredictable and destructive nature.
According to the study, traditional forecasting methods, such as numerical weather prediction and statistical approaches, often fail to consider the complex environmental and structural factors driving rapid intensification. While AI has been explored to improve rapid intensification prediction, most AI techniques have struggled with high false alarm rates and limited reliability.
Meta set to introduce Ray-Ban smart glasses in 2025
To address this issue, the researchers have developed a new AI model that combines satellite, atmospheric and oceanic data. When tested on data from the tropical cyclone periods in the Northwest Pacific between 2020 and 2021, the new method achieved an accuracy of 92.3 percent and reduced false alarms to 8.9 percent.
The new method improved accuracy by nearly 12 percent compared to existing techniques and boasted a 3-times reduction in false alarms, representing a significant advancement in forecasting, said the study.
"This study addresses the challenges of low accuracy and high false alarm rates in rapid intensification forecasting," said Li Xiaofeng, the study's corresponding author.
"Our method enhances understanding of these extreme events and supports better defenses against their devastating impacts," Li added.

Trump orders US wealth fund, suggests TikTok stake inclusion
President Donald Trump signed an executive order on Monday instructing the U.S. government to initiate the development of a state-owned investment fund, which he suggested could be used to generate profits from TikTok if he succeeds in securing an American buyer, reports AP.
On his first day in office, Trump issued an order granting TikTok until early April to find an approved buyer or partner, while expressing his intent for the U.S. to acquire a 50% stake in the widely popular social media platform. Speaking from the Oval Office on Monday, he pointed to TikTok—currently owned by China-based ByteDance—as a potential asset for the proposed U.S. sovereign wealth fund.
SoftBank and OpenAI launch joint venture in Japan to expand AI collaboration
“We could place that in the sovereign wealth fund—whatever we generate—or establish a partnership with highly affluent investors. There are numerous possibilities,” Trump stated regarding TikTok. “But TikTok is an example. There are plenty of other assets we could incorporate into the fund.”
Sovereign wealth funds typically invest in stocks, bonds, and real estate, often financed by budgetary surpluses—something the U.S. currently lacks.
Trump observed that many other countries operate such funds and predicted that the U.S. could eventually surpass the size of Saudi Arabia’s sovereign wealth fund. “Eventually, we’ll surpass it,” he asserted.
Globally, more than 90 sovereign wealth funds collectively manage assets exceeding $8 trillion, according to the International Forum of Sovereign Wealth Funds, a London-based organisation comprising around 50 such entities.
Within the U.S., over 20 sovereign wealth funds operate at the state level, as noted by the Center for Global Development, a Washington-based nonpartisan think tank.
The largest state-level funds—located in Alaska, New Mexico, and Texas—are sustained by revenues from oil, gas, and mineral proceeds, with funds allocated to in-state programmes, including education. While these funds are state-owned, they generally function as independent entities with dedicated investment strategies and personnel, according to the think tank.
Trump has tasked Treasury Secretary Scott Bessent and Howard Lutnick, his nominee for commerce secretary, with spearheading the initiative to establish the fund, a process that will likely require congressional approval. The executive order mandates that a detailed plan—including recommendations for investment strategies and governance structure—be presented to Trump within 90 days.
During his tenure, former President Joe Biden’s administration explored the concept of a sovereign wealth fund for national security investments, but the idea was not pursued further before he left office last month.
Bessent stated that the administration aims to launch the fund within 12 months, while Lutnick suggested that another potential use for the fund could be government-held, profit-generating stakes in vaccine manufacturers.
“The immense scale of the U.S. government and its economic dealings should yield benefits for American citizens,” Lutnick remarked.
Under a federal law enacted in April with bipartisan support and signed by Biden, TikTok was slated to be banned in the U.S. last month unless ByteDance divested its ownership. In response, both the company and some users took legal action against the statute, which the Supreme Court ultimately upheld.
Upon assuming office, Trump—who had attempted to ban TikTok during his first term—directed the Justice Department to delay enforcement of the law for 75 days. The extension has provided ByteDance with additional time to negotiate a deal with U.S. authorities.
Several investors, including billionaire Frank McCourt and former Treasury Secretary Steven Mnuchin, have publicly expressed interest in acquiring TikTok’s U.S. operations. Trump has indicated that “many people” have also approached him privately regarding the matter. Last week, he noted that Microsoft was among the U.S. companies considering the purchase.
WhatsApp accuses Israeli spyware firm of targeting journalists, activists
Last month, San Francisco-based artificial intelligence startup Perplexity AI submitted a proposal to ByteDance that would allow the U.S. government to own up to 50% of a new entity merging TikTok’s U.S. platform with Perplexity’s business, according to a source familiar with the discussions. If implemented, the proposal would grant the U.S. government a substantial stake in the entity once it conducts an initial public offering of at least $300 billion.

SoftBank and OpenAI launch joint venture in Japan to expand AI collaboration
SoftBank and OpenAI have strengthened their AI collaboration by forming a 50-50 joint venture called SB OpenAI Japan, reports AP.
At an event in Tokyo, SoftBank CEO Masayoshi Son and OpenAI CEO Sam Altman discussed their partnership and encouraged Japanese businesses to get involved.
WhatsApp accuses Israeli spyware firm of targeting journalists, activists
Son, holding a blue crystal ball as a symbolic gesture, explained that the AI service "Cristal" could be used by businesses for tasks like planning, marketing, email management, and analysing old source codes.
Initially, Cristal will be implemented across SoftBank's own companies, including Arm, a semiconductor and software firm, and PayPay, a digital payment service. SoftBank has committed to investing $3 billion annually to integrate Cristal into its operations.
“This will bring super-intelligence to the company. I’m thrilled,” Son shared with reporters and event attendees at the Transforming Business through AI conference.
Altman discussed the new “deep research” feature, which allows ChatGPT to perform more complex tasks, such as generating reports by browsing the web and sourcing information much faster than a human could.
The deep research feature will be available in Japanese for the Japanese market.
“This partnership with SoftBank will fast-track our mission to deliver transformative AI to some of the world’s most influential companies, beginning with Japan,” Altman stated.
In addition to their joint venture, SoftBank, OpenAI, and Oracle are part of the Stargate project, backed by President Donald Trump, which aims to invest up to $500 billion in AI infrastructure within the United States.

Samsung Galaxy S25 Ultra Review: A Game-Changer or Overpriced Flagship?
The Samsung Galaxy S series has long been synonymous with cutting-edge technology and premium design, setting benchmarks in the smartphone industry. Continuing this legacy, the Samsung Galaxy S25 Ultra is officially releasing this month. Let’s go over the specs, standout features, limitations, and pricing of the S25 Ultra in Bangladesh.
Key Features of Samsung Galaxy S25 Ultra
.
Design and Build Quality
The Samsung Galaxy S25 Ultra retains the premium build quality that the Ultra series is known for, featuring Corning Gorilla Armor 2 on both the front and back, along with a grade 5 titanium frame. This makes it more durable than the S24 Ultra, which uses grade 2 titanium. Additionally, weighing 218g, the S25 Ultra appears a bit lighter (232g) than its predecessor S24 Ultra, improving comfort for long-term use.
Compared to its competitors, the Google Pixel 9 Pro Fold and Huawei Mate X6 feature foldable designs, which make them bulkier but offer a different experience for users who prefer a larger, expandable display. The Huawei Mate X6, for instance, has an aerospace-grade aluminum frame and is IPX8 water-resistant, making it more resistant to water damage than the S25 Ultra's standard IP68 rating.

Display Quality
The S25 Ultra comes with a 6.9-inch Dynamic LTPO AMOLED 2X display with a 120Hz refresh rate and a standard 2600 nits peak brightness.
However, it is quite disappointing that in the market a bunch of mid-range smartphones are offering higher refresh rates and peak brightness levels. For instance, the realme Neo7 offers 6000 nits peak brightness and iQOO Neo10 boasts a 144Hz refresh rate for much lower price tags. It can be a deal breaker for flagships like the Samsung Galaxy S25 Ultra.
S25 Ultra features a resolution of 1440 by 3120 pixels. Compared to the S24 Ultra, the screen-to-body ratio has increased from 88.5% to 92.5%, offering a more immersive experience.

When compared to competitors, the Google Pixel 9 Pro Fold offers an 8-inch foldable OLED display, making it great for multitasking but with a lower peak brightness of 2700 nits. Meanwhile, the Huawei Mate X6 has a 7.93-inch foldable LTPO OLED display with Kunlun Glass 2 protection, which is a great alternative for those who prefer foldable devices.
Camera Performance
Samsung has made notable improvements to the S25 Ultra's camera system. It retains the 200MP (f/1.7) primary sensor, but the ultrawide camera has been upgraded to 50MP (f/1.9) from 12MP in the S24 Ultra. Its quadruple rear camera setting also boasts a 10MP (f/2.4) telephoto lens and a 50MP (f/3.4) periscope telephone lens. Additionally, Samsung has optimized AI-powered enhancements such as Best Face, which helps improve group photos.
Against competitors, the Google Pixel 9 Pro Fold only has a 48MP primary camera, but it leverages Google’s AI algorithms to produce outstanding images. On the other hand, the Huawei Mate X6 boasts a 50MP primary camera with a variable aperture (f/1.4-f/4.0), allowing for better control over depth of field and low-light photography.

What’s more, the S25 Ultra outshines both in video recording, offering 8K at 30 fps. However, the S25 Ultra bears a 12MP (f/2.2) front sensor that maxes out at 4K like the S24 Ultra.
Processor Performance
The S25 Ultra features Qualcomm’s Snapdragon 8 Elite (3 nm chipset), which offers a 37% faster CPU and 30% improved GPU performance compared to the S24 Ultra’s Snapdragon 8 Gen 3. With an octa-core configuration, including two high-performance 4.47GHz cores, this processor makes the S25 Ultra one of the most powerful smartphones available.
The Google Pixel 9 Pro Fold comes with the Google Tensor G4 chipset, which is designed for AI-based computing but is not as powerful as Qualcomm’s flagship chip. Similarly, the Huawei Mate X6 runs on Kirin 9020, which performs well in general tasks but falls short in gaming and high-intensity applications compared to the S25 Ultra.

Gaming Performance
The S25 Ultra has significantly improved gaming performance due to the Adreno 830 GPU and real-time ray tracing support, making it ideal for high-end mobile gaming. The Snapdragon 8 Elite chipset also enhances power efficiency, allowing longer gaming sessions without excessive heating.
In comparison, the S24 Ultra, while still excellent for gaming, lacks the same level of GPU optimization and AI-driven gaming features. The Pixel 9 Pro Fold and Huawei Mate X6 are less gaming-focused, as they are optimized for multitasking and productivity rather than high-performance gaming.
Battery Life
Like the ancestor S24 Ultra, the latest S25 Ultra comes with a 5000mAh battery. However, the new 3nm chipset in the S25 Ultra allows for better power efficiency. Samsung claims that the S25 Ultra lasts up to 10% longer than its predecessor on a single charge.

While charging speeds remain unchanged at 45W wired, the wireless charging speed has increased from 15W to 25W (Qi2). In contrast, the Google Pixel 9 Pro Fold has a smaller 4650mAh battery with 21W wired charging, making it less efficient than the S25 Ultra. However, the Huawei Mate X6 surpasses them all with a 5200mAh battery and 66W wired charging, which offers the fastest charging speeds.
Nevertheless, the mid-ranger realme Neo7 wins the race against these flagships with a 7000 mAh battery.
Software and User Interface
The S25 Ultra launches with Android 15 and One UI 7, offering seven major Android upgrades, ensuring longevity. Samsung’s One UI 7 is known for its user-friendly design, customization options, and seamless integration with Samsung’s ecosystem.

In comparison, the Google Pixel 9 Pro Fold also offers seven years of updates, but its stock Android experience lacks Samsung’s custom features like DeX mode. The Huawei Mate X6, running HarmonyOS 4.3/EMUI 15, does not have access to Google Play Services, which may be a dealbreaker for some users.
Storage Options
The Samsung Galaxy S25 Ultra offers multiple storage configurations, including 256GB with 12GB RAM, 512GB with 12GB RAM, 1TB with 12GB RAM, and a high-end 1TB with 16GB RAM variant. This marks an improvement over its predecessor, the S24 Ultra, which lacked a 16GB RAM option. It sports UFS 4.0 data transfer technology.
When compared to its competitors, the Google Pixel 9 Pro Fold maxes out at 512GB with 16GB RAM, while the Huawei Mate X6 provides storage options up to 1TB with 16GB RAM, putting it on par with the S25 Ultra in terms of capacity.

WhatsApp accuses Israeli spyware firm of targeting journalists, activists
WhatsApp has accused Israeli spyware company Paragon Solutions of targeting nearly 100 journalists and civil society members using its sophisticated spyware, Graphite.
The attacks, reportedly carried out using zero-click methods, have raised fresh concerns about the misuse of commercial surveillance tools and the lack of accountability within the industry.
According to a report by The Guardian, WhatsApp has "high confidence" that around 90 users, including journalists and activists, were targeted and possibly compromised.

The company did not disclose the locations of the affected individuals but confirmed that they had been notified of the potential breach. WhatsApp has also sent a cease-and-desist letter to Paragon and is considering legal action against the firm.
Zero-Click Attack and Full Device Access
Graphite, Paragon’s spyware, is reportedly capable of infiltrating a device without requiring any interaction from the victim, making it a particularly dangerous tool for surveillance. Once installed, the software provides complete access to the infected phone, including the ability to read messages sent through encrypted apps such as WhatsApp and Signal.
While the identity of those behind the attacks remains unknown, Paragon Solutions is known to sell its software to government clients. A source close to the company claimed that it has 35 government customers, all of which are democratic nations.

The source further stated that Paragon avoids doing business with countries that have previously been accused of spyware abuse, such as Greece, Poland, Hungary, Mexico, and India.
Growing Scrutiny of Spyware Industry
The incident has intensified scrutiny of the commercial spyware industry. Natalia Krapiva, a senior tech legal counsel at Access Now, commented on the matter, stating, "This is not just a question of some bad apples — these types of abuses are a feature of the commercial spyware industry."
While Paragon had been perceived as a relatively less controversial spyware provider, WhatsApp’s revelations have called that perception into question.
This development follows a recent legal victory for WhatsApp against NSO Group, another Israeli spyware maker. In December, a California judge ruled that NSO was liable for hacking 1,400 WhatsApp users in 2019, violating US hacking laws and the platform’s terms of service.

In 2021, NSO Group was also added to the US commerce department’s blacklist due to activities deemed contrary to US national security interests.
WhatsApp’s Response and Future Security Measures
WhatsApp has not disclosed how long the targeted users may have been under surveillance but confirmed that the alleged attacks were disrupted in December. The company is now working to support affected users and reinforce its security measures to prevent future breaches.
As concerns over spyware misuse continue to grow, this latest revelation underscores the need for stricter regulations and international cooperation to curb the abuse of surveillance technologies.
