So this morning while watching YouTube, all of a sudden my volume went way up and I hurried to bring it back down. Then I couldn't use my volume up button or my power button (that was a whole ordeal because after forcing a boot I would get a No Command screen and I thought my phone was bricked) and after getting it out of the hell ordeal, my power button works but my volume key does not. They are not stuck down or anything like that.

I keep my phone clean and I keep it in a protective case. For it to stop working all of a sudden is very strange. Especially it not working in recovery mode was scary. Any ideas or is it time to get a newer Pixel? It's two days away from being fully paid off at Verizon.

QUICK EDIT - I tried putting my case back on and it freaked out again, causing both my volume up button AND the power/lock button to not work like they are supposed to. I can double tap the power button for the camera but I cannot LOCK it.
