Have you tried clearing the cache partition on your phone?

1. Turn off the device.
2. Press and hold the Volume Up key and the Bixby / Power key.
3. When the Android logo displays, release both keys.
4. An 'Installing system update' message may show briefly before the Android Recovery menu options appear.
5. Press the Volume down key several times to highlight Wipe cache partition.
6. Press Bixby / Power key to select.
7. Press the Volume down key to highlight Yes, then press the Bixby / Power key to select.
8. When the process is complete, Reboot system now is highlighted.
9. Press the Bixby / Power key to restart the device.
