If you flash the polish firmware you will receive polish OTAs not UK one... There are not many differences as it's not branded firmware... its like BTU but for poland :)
Galaxy S5 + Snapseed app :)
EDIT: this is in Ireland.. I went with friends to the beach after work, since in Ireland sun is like a christmas..you get it once in a year:D it was just amazing out there, so beautiful I had to take a photo of it:))
I contacted Samsung and they told me to factory reset my phone that "another agent solved the problem with factory reset"... obviously didnt help.. then it was like talking to retard as I asked where i can report this bug since its S5 specific... no valid response whatsoever... i just gave up...
