I have my friend, who uses this cell-phone, i.e. Gionee M7 Power. He has been using this one for about 8-9 months approximately, and he has told me about all the problems he is facing because of this smartphone.
He is a music-addict, and this phone has a lot of Speaker Issues, and even after visiting the Service Center, problems still remain in the speaker part, and this also causes incoming phone calls and alarms to get missed.
Next, the battery life, which should have been good, because of 5000 mAh capacity, Isnt so good, and he feels, on more usage, the phone battery may Die Off Faster than usual.
Yes, the camera is good, but the screen is a bit Less Distinct in dim light.
These are the main problems, for which I feel the phone doesnt give us all the best features or qualities, that it should give at that so high price.
