I bought a Galaxy A50 5 days ago. The first couple of days everything was OK - the camera was working, I shot a few pictures with it and a few slow-motion videos.
Yesterday, when I tried to open the camera app it was not working. Some of the in-app buttons are there, but with no working functionality
At first, I thought the problem is in the camera app and I tried to open Facebook Messenger and to test if the camera is working there, but it is showing only a black screen - the same as in the camera app.
Then I downloaded a 3rd party camera app in order to test if it will connect to the phone's camera, but that app is also not working. It also shows a blank screen.
Summary: Galaxy A50 camera does not work with the phone's camera app, with Facebook Messenger and with a 3rd party camera app. It shows black screen and buttons are missing or not working.
All black screen opens with the 3 android buttons at the bottom, but none of them works. I can't back, I can't go to the home screen, I can't open the recent apps.
Now a few seconds later a message popped up: "Factory camera doesn't respond" with the options to close, wait or send feedback.
When I click on "Close" it closes at last.
One more interesting thing is that the same happens if I select "front camera" instead of "Mega Cam". Just for your information. Now I get stuck in the front camera, too, and will wait for it to pop that message up. Here it is, I click close, otherwise I can't get out of the front camera.
