Samsung is pushing out an OTA update for the Galaxy S5 users in Poland. The update is small and in size and looks like a bug fixing update for Lollipop firmware that was released for the device a couple of weeks ago.
You should receive a notification on your S5 for the OTA update very soon, however in case you don’t get it, just head over to the phone’s Settings » About phone » Software update » and hit the Update button. If it still doesn’t works, you may have to wait for a few hours for the OTA to reach your device.
The update’s firmware version is G900FXXU1BNL7 and it’s also available via Kies.
