The ringer button doesn't work perfectly all the time but good enough for a used phone I guess.

The silent button came pretty glitchy, the battery reader is NOT working correct, and coneting to the internet is a pain if u can deal with that get it.

Mine was shipped with a loose home button and sticky side volume buttons to start

Although the firmware works just fine, the screen clicks like it isnt fully bonded, the buttons are loose and it got really hot from just charging it

Mute button was broken

Touch ID button is loose

The same issues persisted after attempting a hard reset (home + power button) and trying to reset via itunes (plug-in with home button down)
