Good:
Battery life, flash is brighter, doesn’t lag on heavy games, perfect selfie camera, incredible gestures for easy access, stunning swype keyboard and it supports every alphabetical langauge
Bad:
screen off gestures don’t work when the SD card is inserted
Overall: Impressive for non-heavy bytes user but, unfortunately I am a heavy byte user
For Heavy bytes user here is my tips for your storage:
use sd card( 8 gb) store every musics, apk, videos, and everything to my sd card, always clean your storages( trashes, uninstalled/deleted apps file leftover, and any useless apps)
