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?

    I just received my Android 13 update for my T-Mo OP9 Pro on 5/10/2023, and I now have a newfound love for this phone again. Yes, it is late as HELL, but I'm very happy with the update so far.

    I'd try factory resetting the phone. If nothing, then use MSM toolkit to flash back to OS 11 and try updating again. Not to mention, hopefully a version of 13 could be another fix for you also..

  • Can we downgrade if we accept the Android 13 upgrade?  I suspect that Android 13 will destroy my ability to use the native call recording which is why I have kept with OnePlus devices in the first place.  It will likely kill the fooview app I use so often for screenshot screen recording of a section of the screen and stitching screenshots and editing as well which I utilize daily

    It is possible to rollback.  OnePlus, now OPPO, has not restricted the ability to roll back.  Personally, I would say use the links.over on XDA with their walk through.  If.you have any questions about the process or need any help.  Someone usually responds pretty quickly over there.  MSM will completely wipe your device so make sure you back up everything you want to keep.
