I used this set and I’m very very unsatisfied with this model.After using some days my phone get hanged and the speakers a damaged how I don’t know. The sound quality decreases and sometimes the speakers are not working . The phone got hanged every single second . Every time it shows that Unfortunately Android system stopped and after showing this the phone switched off and not started.Sometime camera not working and sometime the SD unmounted by itself.It’s cost around 10, 000 and the performance of the phone is worst.The look of every samsung phone is same . I feel that i’m using same mdel.It sucks a lot of battery. The battery backup is very bad i.e., hardly it gives 2-3 hours battery backup.
