That's not good @Omaroupirat  

Some generic troubleshooting tips are …

• Make sure all your app's in Playstore and Galaxy Store are updated.
• Clear your phone's System Cache Files by turning your phone Off and then from a set series of button presses go into the phone's System Files and clear the cache. No information is lost this way. You may need to insert your headphones or hook upto a computer with your data cable to get to this menu on the phone. https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ 
• Put the phone in Safe Mode which disables your downloaded app's but let's your stock app's keep working. If the issues stop then this highlights a downloaded app as the possible issue. Come out of Safe Mode and start deleting your most recent downloaded app's one at a time until it stops. https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ 
• A very last resort is a factory reset after backing up and removing any relevant sd card.

A Samsung Experience Store or Samsung Service Centre can take a look at your phone.

I wish you all the best with this.
