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

I've had nothing but issues since the update to 12.  My phone doesn't always charge fully overnight, I have to call people twice since the first call always drops/won't connect, general slowing down of the system overall, and now I can't receive phone calls?  This really isn't making me interested in the OnePlus 10 at all.  I might have to go back to Sony or see if the Nothing phone is going to be any good.  There's no point in having a phone that can't receive any phone calls.  

*edit* also, the battery drains much faster than it used to with normal usage.
