The phone is very laggy n it's really very hard to switch between apps. I have done everything n even hard reset the phone. But its same. How you can release such useless phone for high price. It was my mistake buying a Samsung phone.
Kindly follow the below mentioned step to improve the performance of the device:
Check device in safe mode:-
Enter safe mode: Press and hold the Power key, when Power off icon appears.>Press and hold the power off icon.
Exist safe mode: Press volume down and power key simultaneously for 5 seconds to restart the device.
Note: If your device functions correctly in Safe Mode, it is most likely that the issue lies with a 3rd party application that can be uninstalled to resolve the problem
