World cheapest phone in world. Review on Gionee P2S

I don't like this phone because in there phone no software update and this phone sound is not clear . And the screen not work properly touch is bad .And there button not push properly and camera not work at the movement.In there phone the storage show 510 MB but phone storage is available only 410 MB, So friends I have these phone please don't buy this phone I feel very very bad experience about this phone.The design or style of phone is looking like a dummy phone looking like a baby toy this PHONE for a baby not a adults and there other features also not work at time. I bought this phone only 2 months ago and there function was not work at time and there icons miss place from our place.for looks I want to camper this phone to A KEYPAD phone because a keypad phone work properly at the guaranty period. I feel very bad in my hand this phone.5000 is more than this value of phone because this actually from my view this price only 2000.
