Hello there!
Never heard of that before, but just a quick, hopefully helpful search, yielded to clear the cache from recovery:
- First of all turn off your Android phone.
- Once it’s completely turned off. Enter into recovery menu by Pressing Volume Up + Home + Power button simultaneously. Keep on holding the buttons until you see Android figure in the background.
- Now in recovery menu. Locate Wipe Cache Partition. Use volume buttons to navigate to it.
- Now Press power button to select it.
- After wiping cache partition.
- Select on Reboot system now.
See if that helps?
