Hi @ovk 

I'm sorry to hear your experiencing these issues. 

I assume your phone's software is up to date. 

Can I ask you to try these troubleshooting steps. 

• 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. 
• 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 or use a Tv's USB Port 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. 
• The phone has a diagnostic tool found in your Samsung Members App. 
• As a last resort back up and factory reset. 

If I can be of any further help then please don't hesitate. Take care.  😎
