Im experiencing a cracking sound,little bit of flexing creaking on the right side of the frame under the power button which is very annoying and it concerns me about the water resistance of the phone.It seems attached to the display and the back but when i press it i hear the flex creak,its like a part is missing there and its hollow.Does anyone else have this annoying thing?
I'd suggest to ask the retailer that supplied your phone to swap it out @Stoyan11
I wouldn't want to keep hold of a phone that was doing as you state and my confidence in the phone would be reduced.
