Chosen Solution
ZTE ZMax Z970. The volume buttons are randomly responsive, will work for an hour or two before I have to go back to adjusting my volume through settings. I’m not sure if this is a hardware issue or software. Possibly related: adjusting the headphones jack when something is plugged into the phone causes the Google app to open up and listen for commands; sometimes, it will suddenly increase the volume in increments and I have to manually change it back. Where would I take it to be repaired?
You should download the app called Virtual volume button that should fix the problem
Okay so I’m not exactly an expert but press the center of the volume buttons into the phone and that fixed mine actually a little bit to where they are more responsive. If that doesn’t work then play with the buttons to find an angle they work at.
