2. Press and hold Volume Up + Power Button until you see the Android recovery screen.
3. Use the volume buttons to navigate to Wipe cache partition and press the Power button.
4. Confirm your choice and restart your device.

If still you're having problem, better to contact Samsung Support. Thanks!
