Any solution?

Bro, perform reset apps prefrences

settings>applications>click at 3 dots>select reset apps prefrences
or
perform normal phone reset settings
or
check if you have enabled power saving mode
or
Check for any recently installed 3rd party apps

Flash screen..you meant flash notification..(inside Accessibility settings)..
Run your phone in safe mode..to check if any recently installed 3rd party apps are causing this issue..
or
last option factory reset..(but do backup your data)
