I’m using this phone from past 1 month and I havn’t faced any problem as per performance of this device is best in class octa core processor from mediatek is very fast and coupled with 3GB of ram is its other part of its performence.
Now lets talk about camera I will not say its best 13mp camera but it can take quite decent shots and front 5mp camera is also good. 5.5HD display is bright and viewing angles are great .3000mah baterry is also good it gives me around 6-7 hours of screen on time.
One full charge is enough for normal to mild usage . it’s user interface is also good and lite called CoolUi 6.0 is based on android lollipop 5.1. Now talk about its USP its fingerprint sensor its very fast and acurrate and u can store upto 5 fingerprints. Its a thumbs up from me and I recommend you to buy one for you
