I have a few things I can help you with.
First thing is that the only thing I have found is that people have a major problem with the camera and I've had my Samsung galaxy A11 for a little over 2 weeks. Suddenly the camera wouldn't work. I found out that by resetting the data for the camera. First force stop the application camera next go to the storage use settings for the camera 📷 go to clear and clear data clear both of these. That has fixed my problem.
The other thing I have found is when charging the phone if you are going to be using it at the same time don't use the travel charger that came with the phone use a regular one for charging otherwise you may get the message that your phone has stopped charging because it is to hot 🔥. It's not the best Samsung galaxy phone but for the price and quality of most Samsung products I like it .
