Hallo @Jackiee,
Thank you for your message. Is this also after rebooting the device?
If yes, have you also tried deleting the cache memory through the recovery menu? If not, turn of your phone, press and hold the Volume Up, Power, and Home/Bixby buttons until you see the Android logo. After a few seconds you will enter the recovery menu. Select 'Wipe cache partition' and afterward 'Reboot systeem now'.
If that doesn;t work you can try reinstalling the apps and if that doesn;t work facotory resetting your phone. See the link for instructions below. Let us know if it works.
With kind regards,
Ajay
