Samsung Galaxy S21 One UI 6.1 update India

Samsung recently released its March 2023 security update details, which mention fixes for a lot of CVE and SVE items. In the meantime, the company also reveals an important vulnerability fix for Samsung Galaxy S21 Exynos models with the March 2023 patch.

The SVE that reads “SVE-2022-0604(CVE-2023-21459)” fixes the use after free vulnerability in the decon driver. This issue was allowing attackers to cause memory access faults, meanwhile, the March 2023 patch adds proper check logic to prevent use after free.

The security patch details further say that this moderate level of SVE was reported on February 1, 2023. It was affecting the Galaxy devices driving Android 11, Android 12, and Android 13 operating systems with the Exynos 2100 chipset.

The Samsung Galaxy S21 series phones, including the S21, S21+, S21 Ultra, and S21 FE, use Exynos 2100 chipset in select regions, which means the March 2023 patch has fixed this major vulnerability for all these devices.

‘Improper authorization in Exynos baseband’ is also resolved:

Aside from the decon driver exposure, Samsung has also fixed the improper authorization in the Exynos baseband vulnerability – SVE-2022-2678(CVE-2023-21455).

As per the information, this issue was affecting Samsung Exynos models. It was allowing incorrect handling of the unencrypted message as was reported in November last year.

It is worth noting that Samsung is yet to release the March 2023 Android security patch update for Galaxy S21, S21+, S21 Ultra, or S21 FE customers. In fact, it hasn’t started delivering the March patch update yet.

Usually, the Korean company does not delay the release of security patches, but since it is currently rolling out the One UI 5.1 update, we are seeing a delay. However, the release is not far away, Galaxy customers are likely to get the March 2023 security patch very soon.

Google Play Store goverment badge

Google Play Store is rolling out a significant update regarding the app and in-app payment. Android’s native app market has a vast range of applications and games for free. However, there’s a paid app category as well, which users found worth buying as per their preference.

According to the info, the Google Play Store has added a button that lets you create a payment link while purchasing an app or in-app item. You can use this link to ask someone else for payment on your behalf. It’s starting to roll out in India, with expansion expected gradually.

The user who taps the button is warned that the person who’s paying has to know their full email address, and can see the item that’s being purchased. Notably, app developers don’t have to do any additional work to support Google Play’s new “ask someone else to pay for this item” button.

A system share sheet will be displayed to share the payment link through a range of apps and services. Once generated, the payment link will be valid for 24 hours. The payer will have to make successful payments within 24 hours to buy an app or in-app stuff for the sender.

Samsung Galaxy Ring Honor

Samsung will be releasing its Galaxy Ring device in July this year. Potential consumers may have been concerned about picking their ideal size. Well, Samsung will likely offer a Sizing Kit that will be delivered before the Galaxy Ring so you can pick the size.

Earlier this year, Samsung unveiled the Galaxy Ring at Mobile World Congress. As the formal release is scheduled for July, the company is already working on consumer convenience. As everyone doesn’t know their ideal ring size, Samsung prepared a pretty interesting hack.

Leaker EvanBlass revealed that Samsung would ship a Galaxy Ring Sizing Kit to potential buyers. If you are interested in purchasing a Galaxy Ring and unsure about the ring size, you will get a Sizing Kit upon ordering the Galaxy Ring and choosing the “I don’t know my size” option.

Once done, you will receive sample rings, letting you find the best size for your preferred finger. Later, you can pick the preferred size and confirm the order to get the Galaxy Ring delivered. It is expected that the Ring will be available in a total of 9 different sizes.

Samsung Galaxy Z Flip 5 update September 2023 update US

Samsung might launch Galaxy Z Flip 6 Slim and Galaxy Z Fold 6 Slip GalaxyClub reports. While the company is marching towards its July Unpacked, rumors about new Slim models are surfacing now.

RossYoung hints that Samsung might introduce a Galaxy Z Fold 6 Slim. It could have a larger display than the regular phone and lack S Pen support. This variant could hit the market later this year in the fourth quarter.

The Z Fold 6 Slim is model-numbered Q6 Slim, while there’s also a B6 Slim. B6 is the model number of the upcoming Z Flip 6, with Slim also expected. These rumors point out that the affordable foldables might be Slim.

At present, we don’t have any idea of the specifications of the Slim foldables. Earlier, it was reported that Samsung was heavily shocked by the reduced thickness of foldable phones released by Chinese vendors specifically Huawei.

It looks like the Korean tech giant has decided to trim some key specs in order to make foldables thinner. Those who want pro-grade specs would have option to go for strategic models, while Slim variants would extend the choice.
