Great Phone, we can get latest update without any problem I updated from kitkat- lollipop-marshmallow all working fine without any problem, very fast
only problem is lack of storage on 16 GB and Battery life,
otherwise every thing best compare to samsung product no hanging or stuck problem at all .
Advantages
Non-expandable storage
Poor video and audio codec support out of the box
Non user-replaceable battery
Comparatively poor battery life(except for calls). Loudspeaker is on the quiet side
Limited availability at launch
