Samsung galaxy j2 ace has been my 3rd smartphone I bought of samsung series.I am a big fan of samsung smartphones but this phone is a crap ! In terms of storage, the internal memory gets filled up quite fast. You have to use a high memory sd card to compensate with its low internal storage with is just not satisfying. The phone occasionally hangs and many times applications crashes. Obviously, the phone is not strong due to abscene of gorilla glass. The battery backup of this phone surely made me cry. Every now and then, the battery level gets sucked up and battery low alert gets displayed which literally made me so frustated that I gave up on this phone. I am a big fan of samsung smartphones but this phone definately let me down. So I would recommend users better not buy this phone.It will only waste your money!
