"Only battery backup good but contact open is slow continue hanging bad result"
"Speed is good . Gionee Marathan m4 has good performance there is no problem of hanging."
"Awsome product very smooth to use. Photo clearity is"
"Except for metal rims getting hot (48 deg) within 10 min of switching on 4g, & playing Asphalt at highest quality shows a bit of a lag, everything works well. Call quality & reception even with 1 bar is excellent."
