Well, it sounds as though maybe you are suffering a hardware failure of the power button - or - contamination in that area that is interfering with proper operation of the hardware button.

If you are a brave soul, you could check out any of a multitude of A5 teardown videos and see if you can verify that there isn't a bunch of lint stuck in there. If you are not up to doing it yourself, you could take it to a shop that does battery replacements in Samsung devices and ask them to take a look.
