After being able to work well with the app for a long time, I tried to adjust the settings for myself. Unfortunately I can’t get back to Camera without exiting the setting-menu. The settings are so extensive that they confuse me. With a step or two back I could even learn what is right and wrong.
At the moment, horizontal and vertical lines follow a round shape. That’s why I installed another camera app, which unfortunately doesn’t take advantage of the two lenses.

Hi. From top right menu… roll down to settings… reset default settings.
This works, thank you.
the other circumstance - I have to close the camera app first to return to the camera from the settings. Or am I missing something again?
You can use the back key to go back to Cam.
I’ve been looking for that from the beginning. My version 1.53.1
If you go to Settings > Search > Navigation mode
are you using 3 button navigation?
This has the back button.
The alternative is “Gestures” works differently. In Gestures for Back, one swipes from an edge.
Sorry, I can’t find any back buttons in the camera app settings or in the submenus. Why have a three-way button if you just want to go back to the app?
Are we both discussing the same problem?
It is actually standard in all (desktop) apps that I know of that you can return to the app with one click.
No, neither can I, within the app itself.
When I use Camera app Settings, I use the main “Navigation” one click Back button to return from Settings → App.
it looks like this with 3 button navigation
Alternatively some phones may be set to do this “Back action” with a “Gesture” – in this case there is no “Back button” at all.
