I have been using this mobile from last 1 year and I have not found any issue sometime I use it continually for 4-6 hour but never got any kind of heating issue
Sound qualty is very clear and loud
Camera qualty is very good but missing front flash which is not OK for selfie lovers
Touch is very smooth
Overall this is value for money so go for it if don't have much more money to avail the Iphone this phone will do your every work which Iphone and other phone is doing
