Coronavirus can live on a phone’s screen for 28 days, study finds
There is a caveat, though
Smartphones are one of the grubbiest things we handle every day. From our fingers to our ears to our mouths, a human body comes into contact with a smartphone several times each day. Naturally, because of the ongoing coronavirus pandemic, phone sterilizers have turned into the norm. If you haven’t bought into the “clean phone” hype yet, a new study might convince you otherwise. Apparently, the coronavirus can live on a phone’s screen for 28 days.
According to a study conducted in Australia, the specific strain of SARS-CoV-2 responsible for today’s pandemic can survive up to 28 days on common surfaces including “glass, stainless steel, and both paper and polymer banknotes.” Further, the study also tested common substrates like vinyl, a material found in screen protectors.
Non-porous surfaces — like glass and vinyl — still had the virus after 28 days. Meanwhile, porous substances — like cotton — had the virus for only up to 14 days. Of course, there is a rather large caveat: The study happened under 20 degrees Celsius, a far cry from normal room temperature.
Countering this caveat, the study also conducted the same tests under 30 degrees Celsius. The virus survived for up to 7 days on steel and glass. It survived up to 3 days on vinyl and cotton. Also, at 40 degrees Celsius, the virus survived for only up to 48 hours on all surfaces.
Now, before you throw away your smartphones for good, remember that the tests were conducted under controlled lab conditions. The results do not indicate what might happen in the real world.
Besides the controlled temperature, the study applied the virus without mucus. It’s another important caveat since transmission usually occurs through contact with droplets. Even outside of a body, mucus contains white blood cells, which can reduce the virus’s survivability outside of a host.
Adding to this caveat, the study starts with an even more important warning: “the role of fomite transmission [that is, surface-to-body] is not yet fully understood.” If anything, the test merely proves that the virus is much more durable than expected.

MediaTek unveils Dimensity 9500s, 8500 mobile processors
For flagship, premium mobile devices
MediaTek has officially unveiled the Dimensity 9500s and Dimensity 8500 mobile processors built for flagship and premium smartphones.
These latest platforms are meant to propel performance, gaming, and efficiency on higher-end mobile devices, while also introducing improvements in AI, imaging, wireless connectivity, and more.
Dimensity 9500s
The Dimensity 9500s adopts a flagship 3nm process and an All Big Core architecture. Its octa-core CPU utilizes one Cortex-X925 ultra core with up to 3.73GHz of clock speed, three Cortex-X4 premium cores, and four Cortex-A720 performance cores.
Together, the system empowers devices to fully unleash powerful performance while staying energy efficient.
Moreover, the Dimensity 9500s integrates the Immortalis-G925 GPU for a full-frame, immersive experience for heavy mobile games. This includes support for advanced ray tracing.
In addition, adaptive game technology 3.0 and frame technology 3.0 improve energy efficiency significantly to prolong battery life.
Meanwhile, the flagship NPU in the processor is optimized for generative reasoning and multi-modal models for a more powerful flagship edge camera and greater content generation capabilities.
The chip supports high-frequency functions like post-processing of live photos, AI photo editing, AI content summarization, and more.
Lastly, the Dimensity 9500s is equipped with an advanced MediaTek Imagiq image processor, which supports real-time 30fps motion tracking and 8K full-focus Dolby Vision HDR video recording.
Dimensity 8500
Equally energy efficient is the Dimensity 8500, which has a 4nm process and All Big Core CPU architecture.
This is composed of eight Cortex-A725 cores with a frequency up to 3.4GHz. The chip supports accurate scheduling technology and DDR5 memory with higher transmission speed so users can enjoy smooth and long battery life for daily apps and multitasking.
With an integrated Mali-G720 GPU, the Dimensity 8500’s peak performance is improved by 25% compared to the previous generation. And yet, its power consumption is reduced by 20%.
For gaming, the processor can bring players a refreshing experience with full frame stabilization, rapid loading, and high energy efficiency.

Samsung teases anti-shoulder surfing privacy feature
A “new layer of privacy” coming to Galaxy phones soon
Samsung has teased a “new layer of privacy” to shield users’ phones primarily from shoulder surfing.
Although there haven’t been any specifics yet, this “new layer” could be quite literal, as in an added display technology on Samsung devices.
Samsung says users can customize it to raise their guard with specific apps, or when entering access details for more private areas of their phones.
Moreover, there are multiple settings for adjusting visibility. This way, users can limit what others can see based on the level of privacy protection they need.
They can likewise choose to protect specific parts of the experience, such as notification pop-ups. In a way, it’s a tailored approach that lets users fine-tune or switch off entirely, rather than a blanket one.
It also eliminates the need to go through apps one by one and adjust settings, as in the case of notifications.
Samsung adds that the process took five years of engineering, testing, and refining, hence the careful and deliberate roll-out instead of a sudden one.
This process included studying how individuals use their phones, what they consider private, and how security should feel in everyday life.
The result, Samsung says, is a fusion of hardware and software expertly calibrated to protect users while on their phones.
This latest development is part of a series of Galaxy innovations to keep users safe. Samsung has been introducing topnotch mobile protection with Knox Vault, Knox Matrix, and more features.

Samsung Galaxy Z TriFold reveals US$ 2,899 price tag
It’s still cheaper than the Huawei Mate XT.
Late last year, Samsung finally revealed the Galaxy Z TriFold, its official entry into the three-paneled market. Even only from its initial announcement, the Galaxy Z TriFold already looks mighty good, more so than its Android-less counterpart from Huawei. But, as with everything, it still depends on the price. How much will Samsung’s trifold phone cost? Now, we have an idea.
Today in the United States, Samsung has announced that the Galaxy Z TriFold will already be available in the country starting this week. From January 30, users can start trying out the phone for themselves in Samsung Experience Stores. They can also grab the device through Samsung.com.
Because the phone is already available, the price tag is out as well. In the United States, the Galaxy Z TriFold will set you back by at least US$ 2,899.
Despite how eye-watering that price is, it’s still a step below the Huawei Mate XT when that launched last year. (For reference, the Android-less Mate XT launched for a miserable EUR 3,499.)
Still, spending almost three thousand dollars on a phone might not be the most appealing decision for a lot of people. This price is also almost a full thousand dollars more than the Galaxy Z Fold7, which starts at US$ 1,999. On the bright side, the Galaxy Z TriFold is taking a big step in “democratizing” the trifold market before it takes over the industry.
If you’re interested in adding this to your cart, the Galaxy Z TriFold has a huge 10-inch screen, a custom Snapdragon 8 Elite chip, 16GB of RAM, and up to 1TB of storage. It also has a 200-megapixel main camera and a 5600mAh battery.
All that in mind, is US$ 2,899 a justifiable price for the Galaxy Z TriFold?
