I bought this phone from flipkart with jio preview offer about 4 months ago. that was my worse decision. this phone is a real crap. I will tell you why.
Firstly if u use 4g data the battery can't last for even 3 -4 hours. if u try to charge your phone while 4g data on. forget about charging , the batter will keep droping. I use hotspot from this phone and put it on charging. lemme tell u it's gonna switch off after 6-7 hours even when the phone charging. because on 4g data this phone is not able to charge itself. thats really disappointing. display quality is very very poor. if u wanna sèe anything on display u must be right in the front of screen. otherwise it looks black if move a little towards right or left. and one more thing u can see anything in the sunlight.
So that's my experience with this phone. this phone is not worth spending 4200 rs. there are many other better options available in the same price range. don't get fooled by lyf phones. they just sucks.
