When my iPhone 8 Plus is verifying the update the screen suddenly changed into a little black in colour and there was nothing in the screen. For a long time it didn’t started updating. I tried to turn it on but i can’t. I connected my phone to the charger and then it booted up and started updating. (58% was the charge % before i connect it to the charger. ). And the main problem is, after updating to 13.4 when I’m using my phone and if i press the lock, button it will lock my phone and my screen will be black but immediately my screen will again wake up and will show the lock screen.I faced the same problem for 2 days. So i again rolled back to 13.3.1. Still I’m in 13.3.1. And the problem is not continuing. I don’t know why this happened. Now i updated to 13.4.1. The same problem continues again. What to do irobin bro?
