My Samsung a70 screen doesn't sleep when it's not charging, started after the phone gave me a moisture warning for moisture that wasn't there. The phone has never been wet and moisture warning started doing up while the phone was beside me while sleeping. That moisture issue stopping after about a week, now when it's not plugged in it acts as if there is a cable being connected and disconnected and the screen won't sleep. This is killing my battery! I have already asked for a replacement from my network provider but they won't replace it for me. Can anyone help?
I have tried another charger and the problem still persists. I have wiped the cache partition and done factory reset but didn't work. Have checked for obstructions but nothing there either.
The following post contains instructions for resetting / overriding the USB driver - seems to fall over when waking up from sleep mode (charge-only).
It worked for me.
