G900FXXU1BOA3 Galaxy S5 Android 5.0 Lollipop Update Arrived in UK, First firmware build in 2015

The Android 5.0 Lollipop update has finally reaches in UK Samsung  Galaxy S5 users.  A unique software build number G900FXXU1BOA3, indicating a fresher build this year. The three last digits letters "OA3", the  "O" basically emphasized as a date of a year "2015", while letter "A" holds the first month of the year which is "January"  and the number "3" shows how many revisions has its made.

In addition,  if one might have to ask why Samsung had to released another firmware build version in UK whilst the rest of European countries has the same build version. Well, maybe it just happens that UK's Galaxy S5 just got delayed a bit and there is nothing to argue with that. If we take a closer look to the firmware build G900FXXU1BOA3 itself, it has a similar changes-value to the previous Android 5.0 G900FXXU1BNL9. It is simply means that nothing more any special added features to it. But noting that the G900FXXU1BOA3 is the newer build and had been into several revisions, then there is a possibility that it might be something a lot better than the previously rolled out.

However, the United States version of Samsung Galaxy S5, including  AT&T, T-Mobile, Verizon and  Sprint has no signs of any official Android 5.0 Lollipop update yet. And so does in Australia, New Zealand, Africa, Middle East and Latin America at this time being. But let's hope that it will going to arrive very soon!
