Gionee M2 is such a bad phone that you must avoid it using it in public. The sound system is of course bad as sometimes I can’t hear to my ring tone even when my Sound volume is full.
The phone is very heavy and you may feel burden to carry it in your pocket.
The style is third class, the themes in the phone are of old times. I feel awkward to use my phone in such themes in public.
It comes with a back cover with it if you order it online. But the glue on the cover it so loose that it got removed in the very next week of its use.
The square shape of the phone is very cheap type and it is pretty embarrassing to use it.
No matter how cheap the price is, yo must not buy this phone as the battery life drains faster than any phone else. Though the battery life is very high after an year of usage it gets damaged.
