How to clear the cache on the Galaxy S6
1. Turn off your S6
2. Press and hold the Power, Volume Up and Home buttons simultaneously.
3. You can release them when you see the Samsung logo with Recovery booting written in blue at the very top of the screen.
4. You will be brought to the Android System Recovery screen (or a custom recovery if you have one installed – if so, your steps will be slightly different, but basically the same as described here).
5. Use the volume buttons to scroll down the list to highlight Wipe Cache Partition and use the Power button to confirm your selection.
You'll see that the cache clear has worked at the bottom of the screen.
7. You'll see a notification at the bottom of the screen in yellow to show that the system cache has been wiped.
8. If Reboot System Now is not already highlighted, use the volume keys to highlight Reboot
System Now and press the Power button to confirm.
Once you've cleared the cache partition you can simply Reboot System Now.
9. Your Galaxy S6 will reboot with a fresh system cache.Clear cache partition for
