I have a hardware problem my power button does not work and has become very sensitive

So I was just playing my favorite game ingress one day and suddenly my phone went into a boot loop. I took out the battery and put it in but It would just not start properly then I searched on the internet that y was it happening it said that your power button has become sensitive now samsung service centers are saying u need to get the motherboard changed but I know that replacing the button will make it fine ( right now I took thw button out I mean the button which we press to turn off the screen but the motherboard button is still there.) So is there anything which I can do myself to repair it at home itself because samsung service centers are sayibg tha there is a problem in the software.

Can the volume buttons become a power button?

The volume "rocker" isn't actually a rocker but just two buttons with a bridge over them. Is there a way to make it so that pressing both at approximately the same time functions like a power button? I find the double tapping isn't always reliable and the real power button is hard to reach.
