Binned off my S4 not to long ago because of its shonky battery and random software glitches even after reseting to factory it did the same. Screen wise i cannot see the sense in the edge version its a gimmick. Loss of removeable batteires and the SD slot is going to hurt this phone lots of people pile things onto their phones and will take the SD card from one to another. Now they cant. Im with Shirty, picked up a motoG pretty mid range phone couldnt be happier with it. Infact I find the slightly smaller screen actually nicer to use.
i have a great distrust of phones now, they seem so get slower and slower over time, even with a factory reset. Built in obsolescence I reckon.
