Question

Galaxy S20 camera does not work

Answer 1

1. Force restart your phone

   Most importantly, refresh your phone's memory by doing the forced restart. It is a simulated battery removal that not only updates the memory but also reloads all services and apps. 

   It is always possible that such a procedure will help you resolve this issue, especially if the camera was working properly prior to the problem. 

   1. To do this, press and hold the volume button and the power button for 10 seconds. Your phone will turn off and on again. 
   2. When the S20 logo appears on the screen, release both buttons and wait for the restart to complete. 

   If the camera still doesn't work after that, move on to the next solution.
    

2. Clear the cache and the data of the camera

   This will reset the camera app and all of its services. If this is just an issue with the app or some of the services, this procedure will surely fix it. That's how it's done: 

   1. Switch to the screen on which the camera symbol is located. 
   2. Tap and hold the Instagram icon until the options appear. 
   3. Tap App Info. 
   4. Touch Storage. 
   5. Tap Clear Cache. 
   6. Now tap on Clear data and tap OK to confirm. 

   After this process, try to see if the camera is still not working. 
    

3. Factory reset your phone

   If the camera of your Galaxy S20 could not be repaired in the first two steps, you should decide to do a reset at this point. If it's just a problem with the app, some settings, or the firmware, a reset will fix it. 

   But before you actually reset your phone, make sure you make a copy of your important files and data as it will be erased. You may find it difficult to restore them after a reset.
