The speculation has been widespread. Some suggest that the Exynos 2600 application processor (AP), produced by Samsung Foundry using its 2nm GAA technology, will be the driving force behind the majority of the Samsung Galaxy S26 models, including the Galaxy S26 Ultra in certain regions.

We have now a working root for T-Mobile Samsung Galaxy S3 latest 4.1.1 Jelly Bean OTA update build T999UVDLJC. Again, this root method has been proven safe, since it is already 100% tested from earlier released - T999UVALH2, T999UVALJ4 and T999UVDLJA. The best part of this root method is that, it doesn't trip the binary flash counter of your Galaxy S3 and then you can still receive any future official update like the 4.1.2 that might probably will be coming soon.
This rooting technique uses the the original stock firmware "UVDLJC" which already pre-injected with root image, and once installed it will automatically root the device, without having any trace as modified. This is perfectly works for those Galaxy S3 users who only wants the original or stock recovery, but it also works for those who wants to install any custom ROM or any custom recoveries like CWM and TWRP.
