Re A13, go into Settings > Advanced features > Motions and gestures > Double tap to turn on/off screen. This works, otherwise this phone is pretty much useles with the power button failing after not even two years.
@raulmirut6519 there's a video on that from ITjungles, "how to turn on Samsung a20 with broken power button". The steps are as follows: Hold both the volume up and down key on your phone, While doing this, connect a USB cable cable from a computer to your phone, After a few seconds , a message should pop up, When this message comes, press the volume down key, not the volume up key! Now the phone should turn on and you can apply the steps shown in the original comment.
Thank you! Mine broke and the press power button 5 times emergency thingy was going off all the time. I can't turn that setting off on my a52 so instead of replacing the whole thing I just removed that tiny button and it fixed the problem! To turn the screen on just go to settings and activate the double tap option
I cant believe youre not concerned about shorting any leads or contacts when using those sharp metal tweezers with the battery still connected. Id suggest to anyone going to try this to use plastic non conducting tools
