Error in displaying images

Sometimes after saving the photos, the photos are partially obscured.
I have a Samsung Galaxy J3 with Android 8.0.0 and I use the default app “Camera” to take photos.
What can I do to solve it?

Hi, are you able to take a prinscreen from that situation, thanks.

This is an example.

Thanks.

Have you tried to download another photo app than the default Samsung’s?

Yes, but I have the same problem. Do you suggest me a photo app?

Thanks

Sometimes the app saves photos as files and not as images, but the format is always “jpg”.
