I would try wiping the cache partition on your device and see if that helps any.

- Turn off the device.
- Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
- When the Android logo displays, release all three keys.
- An 'Installing system update' message will show for 30 - 60 seconds before the Android system recovery menu options appear.
- Press the Volume down key several times to highlight wipe cache partition.
- Press the Power key to select.
- Press the Volume down key to highlight yes, them and press the Power key to select.
- When the wipe cache partition is complete, Reboot system now is highlighted.
- Press the Power key to restart the device.
