I have been using this phone for last 4 months .
There is no phone hung issue . No heating issue at all . Touch is very responsive .
Camera quality is good in rear camera compared to the front one.
Battery backup is good . We have battery saving/ultra battery saving options. That works well .
Phone external look is good .
Only problem I would say is sound is not up to the mark . Speaker is not good. If you see any movie/listening songs in speaker, that will not be up to the expected level . So we have to use headset to hear.
