That's not good @Benjamin24 

Here are a few generic tips you could try.

If they don't work then seek support from a Samsung Experience Store  / Samsung Service Centre 

  1. Settings, General Management,  Reset, Reset Network Settings. 
  2. Clear your System File Cache vai the instructions in the Samsung Link. You may need to hook upto a computer or insert your headphones to get to the recovery menu. https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ 
  3. Back up and Factory Reset as a very last resort.

You arent the first to experience this. People have been experiencing this issue on their s21 ultra since the July security update and its still not been fixed. Do you have a 🚫 sign showing in the signal area? Can you post a screenshot?
