Its a one of the worest phone from samsung. Samsung galaxy j7 is become warm when we charge a phone , its so user friendly but when the high level games we install the phone will be hanged. Its internal storage 16GB. When the phone memory full 15GB then also the operating system become very slow. In the features he says 48hrs battery time but it gives only 12hrs batttery time. In this mobile price we get best mobile from motorola so please think once.
