Lenovo a7700 is a 4g mobile with 2gb ram .its rear camera is 8 mp and front camera is 2mp and its android secure is 6.0.1 and its battery life is about 2900mh. It is dual sim mobile with ( 4g+ 2g) . Its resoulution is 1200×720 so thats good its cost doesnt coinside with its features i.e its cost 8, 500 at shops and 7, 500 at online. It would be better if its front camera is increased and also it 2nd sim should be 4g it would be better. Friends I have bought it for 8, 500 and inserted jio sim in it after 2 months the phone is getting slow and lagging and it has no special features and its visulalitic effects are not good. so I advice you to not to buy this waste phone it hurts you . and I advice you when you buying phones see its android and camera . Thank you .
