Samsung has started pushing out a new update to its Galaxy S7 and S7 edge smartphones. Currently hitting unbranded units in some European countries, the update bumps the firmware version to XXS1BPJ1 and brings along Android security patch for the month of October. 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
