Just got the tmobile android 12 update on my Oneplus 9pro global version and its causing issues
I have the global version of the one plus 9 pro and have always stuck to tmobile firmware cause I need wifi calling/texting. Just got the android 12 update today. Now my phone thinks its always charging even when not plugged, battery drains twice as fast, no 5g, no wifi calling/texting.Also my bootloader is unlocked but the phone is not rooted. Anyone else having these issues or have any ideas on how to fix them?OnePlus 9 Pro's Battery really s.cks
OnePlus 9 Pro's battery life is terrible, after using Spotify for 1 hour at night, YouTube app is running in the background, but YouTube is not open! In battery settings this looks. I left the phone with 38% and when I woke up it was down to 21%, it's clear software problem T-Mobile or OnePlus whoever is responsible should fix the problem!!!
