What have you tried to help resolve this @leannaaaa92 ?
Did your phone work OK before ?
May I suggest these generic troubleshooting guides
- Clear Cache Files from the phone's System Partition Section > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too.
- Make sure all apps are updated in your Playstore and Galaxy Store.
- Ensure your phone's software is updated
- Try Safe Mode > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict.
- Ultimately as a last resort back up and factory reset.
- There is a self help diagnostic tool on your Samsung Members App.
- A Samsung Service Centre can run a diagnostic on your phone.
If I can be of any further help then please don't hesitate. Take care. 😎
