Samsung may produce the top-selling Android flagships, but that doesn't mean buyers don't encounter a few bugs.

Some Galaxy S7 and S7 edge phones apparently suffer from malfunctioning volume down and power buttons. You press either one, whether to reduce noise or wake your device from sleep, and nothing happens. In either case, it's quite a big deal. You're either stuck with a blank screen or notifications coming in loudly as you're trying to silence your phone.

We haven't covered this issue before, but SamMobile provided some coverage a few months back.

Now T-Mobile is rolling out a fix. An over-the-air update is going out as software version G930TUVU2APD7 (for the S7) and G935TUVU2APD7 (for the S7 edge) with the following changelog.

What's New:

  • Power and Volume key fix
  • Various system improvements

There you have it. The update may take some time to hit your device. If you're a T-Mobile customer with either phone, share your experience with us below.
