I have bought this phone 3days ago only. But now I think it is my biggest mistake to buy this phone. The sound quality of the system is average only. The phone is not best at all. The processor of the phone is slow sometimes it got hanged. The battery is given of 3310 mAh but it can be used for only for 9-10 hours continuously. The cameras are the worst or blurred not capturing the best photos its bokeh effect is not properly respond sometimes it will blurr half of your picture . The one of the best reason to buy this phone is it has 7.0 noughat which is not latest. The phone is also not upgradable to Oreo. The front camera of the phone is of 8 megapixel only. The back or rear camera are of 16+ 2 megapixel only. I recommend you to all not to buy this phone instead of this buy 10. Or g which is best in this range
