Troubleshooting Oasis 2019 power button issues

The power button on my 2019 Oasis isn't working. I have had it 3 1/2 months, no drops, no issues but out of no where the button isn't working.

The only thing I've done differently is manually update to 5.13.3
I can't imagine that would have an effect but it's the only thing I can think of.

I called Amazon, they sent me a replacement but it as dented corners and scratches on the back. If there's no way to get a mint condition one (like mine that has been living in a case since day 1) then I'd rather try to find a fix for it or live with it.

Any suggestions?
