It is really a powerfull phone. Its performance is satisfied according to its specifications
When it comes to gaming it can run any game brilliantly without any lag. Its quite smooth but yeah screen is a factor as its just 5.2 inch, if it was a 5.5 inch it would have been perfect.
Camera is quite good but could have been better in this price range specially the selfie camera.
Battery backup is satisfactory but the phone heats up while charging.
Sound quality is very bad. The speaker is not loud at all. Its half the volume of other phones.
Earphone jack is at the bottom which is very uncomfortable.
Overall its a messed up phone has a good cpu but for gaming but lacks in other aspects like screen size, speaker etc.
If you can compromise in these little problems then its a value for money. Go for it.
