Hello friends, it’s battery backup is so bad, it took an hour just to make a call. It’s very slow smart phone and always go back with double tap, price is quite high for the other phones the battery draining very fast as well as the phone hangs. It’s front camera is some nice but back camera is not good at all, the device is totally disappointed me, because just 1gb ram and 16gb internal storage, opposite neo7 is very fun phone compare to other oppo phone, then also the problem appears one by one. Many apps do not work in this phone and the remotes app also is not working, the camera quality will automatically decrease after using a few months, we we use the internet hardly four hours continuously then over the cell is dead, thank you
