The phone is very good at its value. I bought this phone 3 months ago and I didn’t face any problem. Its doesn’t hang because it has 2gb of ram and 16 gb of internal storage. As well as it has long battery backup with 4050 mah battery. And when we comes to sound quality its not better as it shoud be. But yes its not wrost also its average. Camera quality is good with screen flash. And the main thing I like about this phone is that it has snapdragon processor which help to improve the phone quality.so I will suggest you to buy this phone without any confusion.
Thank you so much and best of luck with for your new phone.
