I’ve been using this phone for 2 years now.Haven’t faced any major issues till now. The only two issues I have faced till now is with speaker n sim slot I had change both of then and that cost me around 1k.Speaking about the batter backup its very poor, with heavy use it hardly lasts around half day and with normal use it can go upto one full day.The reason why I love this phone so much is that it keeps getting app updats every now and then so we never get bored by using the phone.zen ui too gets a lot of updates.camera is one of the best in the segment, the detailing is way better that other phones in this segment. If you are planing on buying one I would suggest you to go for it.
