I was very much aware of the heating issues the reason I bought the mobile is for the v.r. feature theater max and for its dolby
Camera is good even in low lighting I would rate superior compared to my other mobile sony z3 plus as far as low light is considered.
Processor speed is also fast there is no lagging while playing sniper and other simulation games.
Comes with inbuilt call recorder so need not install one.
Only issue is with the battery had to charge it twice a day if we watch movies or while gaming
