Press the Volume down key several times to highlight Wipe cache partition.

Press Bixby / Power key to select.

Press the Volume down key to highlight Yes, then press the Bixby / Power key to select.

When the process is complete, Reboot system now is highlighted.

also you may need to plug your phone into a laptop or computer to do it.
