I bought this on first sale and I used almost 13 days. So far there are no hanging, heating, lagging issues, it runs smooth and fast. Theater max is great experience especially 3d movies with vr headset. Battery packup is decent one and half day in normal use. Front camera take good picture where as rear camera was not upto the mark, low light photography is little bad. it has hybird sim slot you can use either two sim or one sim and memory card. display is good and audio is good so far overall its a good phone
