Question

Just got the tmobile android 12 update on my Oneplus 9pro global version and its causing issues


Badge

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?

Definitely appreciate you helping; I just can’t find anything that has update in it in apps (i’ve looked) besides “Dynamic System Updates” “Built-in App Updates” and “Config Updates”.  The update doesn’t even show up in the notification bar, it only shows up under system update in settings, and will always show installation paused and then just go ahead and update for me on it’s own.  Very frustrating :(

 

I’ll post something on XDA and have been reading both them and OnePlus forums to find a solution but thus far it’s not been anything that’s worked.  I’ve also tried safemode but it’s still being forced during that.

I rolled back to Android 11 (after updating to 12 via T-Mo OTA) using MSM Download Toolkit. 

I didn't like losing advanced reboot access & the 'seconds' option on the status bar clock. Also, my Nothing (1) app wasn't optimized for Android 12 either and that was huge because it interfered with my earbuds. My navigation bar sometimes stayed in the landscape position after rotating back to portrait. Those things alone convinced me to ditch Android 12 for now on my T-Mobile OP9 Pro.

Thanks for sharing with us. I was looking for something similar and fond it from here. Thanks guys
