I have purchased this phone 4 months back and till date didn’t face any kind of issue regarding the speed thanks to its 3GB RAM, heat etc.
the biggest advantage of buying this phone is its large screen size, you will get 6.4’ Gorilla Glass 3 Screen which will give you ownsome gaming and movie watching experience, sound quality is also good, its very slim and stylish, battery backup is also good. its fingerprint lock feature makes your phone secure.
