Gionee Marathon M3 is a nice phone which is easily compatible and reliable.
Specification:
It has a 5 inch screen
Back camera 8MP while Front camera 2MP
1.3 GHz quad core processor
8GB internal memory
2GB RAM
3.5mm headphone jack
Battery of 5000mAh
Disappointments:
Phone has all good qualities but the qualities which lag it behind is the battery is of 5000 mAh but it discharges very soon it is the major drawback and the battery is non-removable so we can’t change it also.
And another major drawback is of front camera which is not that good to take selfies. Images taken are sometimes blurr.
Thank You
