I bought this phone 8 months ago, in early 2-3 months it works really well. But now it gets hanged most of time. Sometimes screenlight gets on after 10-15 seconds later while someone is calling me. Other features are awesome, camera quality is best like all other Samsung’s mobiles, battery backup is also very good. Once u charged it 100% it can easily runs upto approx 36 hours. It is best in every aspect except its hanging problem. I think company should take this problem seriously and should work on it.
