I used this phone only for a month. It has great features and it has everything what a phone should have under this price range. Also it is one phone which has more number of custom ROMs than any other chinese re-branded phones in market.
Now where does this phone falls down is the quality of components that it use. It is very delicate and it has no resistance to water/sweat/high temperature. Slight sweat from my body rendered this phone useless that its most of the sensors gone caput and the phone doesn’t start now.
I would suggest to invest in branded phones that is durable and reliable rather than going for phones in this price range which will have shorter life span and can give sudden death one day.
