I bought this phone a couple of years ago and have faced a lot of problem. However I am going to write both pros and cons of buying it
Pros
The number of features we get compared to the price is fine as it doesn't cost much.
The camera quality of the phone is still better than many other phones.
Cons
The phone has 2 GB ram and 16 GB internal memory which is completely insufficient in today world of Whatsapp and other social networking.
The phone becomes slow as soon as the memory reaches it's peak.
Conclusion - If you are thinking for a one time investment, never buy it.
