Samsung already updated its Note20 duo with the October security patch at the start of this week but now a new update is seeding in Germany for the Galaxy Note20 Ultra which aims to improve battery life on the top-tier Note.
The new firmware comes with the N98xxXXU1ATJ1 build number. It also brings improvements to the camera app and Dark Mode. We expect to see the update pop up in more regions in the coming days and it should also come to the Galaxy Note20 soon enough.
I used to had the overheating problem but it appears to be solved by the latest OneUO3.0/Andorid 11 Update. Have you guys tried that?
In Pakistan we still not get update of October 2020
I noticed a HUGE difference after the update, so much I did a bit of research to see if battery endurance was part of the recent update
