Purchasing samsung galaxy j1 was a bit mistake. the phone gets hang every time while using multiple task. the RAM of the phone is very less, cant install big apps, cant play big games. battery backup is really poor. rear camera is good but front camera is very bad. and the calculator always suck. i have used two samsung phones but this one is very bad experience. as far as I think with this price much better phone, with much better features can get. i suggest not to buy.
