New IOS 13.4 problems with iPhone 8 Plus

Hi,

As you know, recently Apple has released new IOS 13.4, the update seems great for iPhone XR’s but not same for iPhone 8 Plus. I will go easy and explain the problems fastly;

•Assistive touch isn’t on the screen, I’ve tried to turn it on and off but, nope.

•Phone locks down without any reason just stops responding, a few minutes later reboots and fine. (I own it for 3 years but never seen something similar until today)

•Battery performance is dropped, while the percentage is still the same.

I think these issues are technical, I’ve reported it to Apple but all sugestions that might help to solve these problems are very welcome. I will be so glad if you could help me, and will be glad if Apple see us.

Thanks,

Berke.
