Back Buttons Not Working

[EvieDash9]

Hello, recently I've noticed that the buttons on my LG K7 don't work all that well (no duh).

The volume down works fine, the power button works if I press it in a certain spot, and the volume up only works in a very specific spot I haven't been able to pinpoint. (I have to mash my finger all over it for like a minute to get it to work.)

I've googled this more times than I can remember and nothing has worked.
I don't want to hard reset or seriously screw up my phone in any way, and I can't afford to get a new one.
Help?

I have the same problem and i found a crack in my rocker switch this lets the power button loosen and the pressure of the up and down buttons will be misplaced missing the actual button. The part is cheap online and easy to remove/ install. One screw in the bottom right corner of the silver mounting plate once that plate is removed the buttons should just slip right off. fit the new panel in place fasten the silver mounting plate ( or whatever color you have). Hope it is not too late /
