iPhone XR after taking screenshot, cannot lock screen
Recently I updated my iOS to 13.5 and then 13.5.1, the problem keeps annoying me.
I found the issue was happening some days after the upgrade of iOS. I took screenshot with using the volume + button and also the Power On/Off button. I noticed that after taking the screenshot, the Power On/Off button does not work on Lock my screen. I double checked and it can be reproduced again and again. Every time I met this issue, I need to reboot my iPhone. I also checked if this is the Power On/off button issue, and proved that there has no issue. I pressed the Power button for long time, it prompts for restart the iPhone or Shout for SOS etc. So it means there should have no issue on the mechanical side (i guess).
I tested several days without taking any Screenshots, there has no issue on Locking. But once I take the screenshot, the issue appeared.
