I am using this phone from last 4 months and still it performs well. No lagging of any app and it gives you high end security for your device as it comes with a fingerprint sensor which works as ease. Camera quality is good but front camera could have been better but its fine for the price. The 2 gb ram and a quad core processor makes sure that the device works with ease and without any problems or slowing down. Micromax has been good by providing software updates too so yeah it definitely deserves 4 stars but not 5.
