T-Mobile has started pushing out a new update to Samsung Galaxy S7 and S7 edge smartphones on its network. Arriving as software version G930TUVU4APK1 and G935TUVU4APK1, respectively, and weighing in at over 80MB, the update brings along Android security patch for the month of November. As is usually the case with OTA roll outs, it may take some time for the update to hit your device. Meanwhile, if you feel impatient, you can manually check for the update by heading to your handset's Settings menu. Via
