[LG G6 Android 8] After watching a video in the gallery, goes back to main screen

[Android Central Question]

Hi,
I've got the latest update of Android 8 to my LG G6 .
Now I get some strange behaviour:
I'm watching a video in the gallery. After the video, I want to go back to the gallery, to view other stuff. But, the back button sends me back to the main screen!
If I open the gallery again, I go back to the same video I watched.
Only by cleaning all running apps, I can get to the main gallery page again.
I don't see this issue when watching photos.

Any idea?!
It's super annoying

Welcome to Android Central! When the video is done, does it just show a still of the last image? If you tap the screen, do you see an X or back arrow anywhere?

Hi, glad to be part of the community!

Yes, just shows the last image.
I have back arrow, Delete, share, and many other options in the 3 dots.
But clicking back on the screen, or the home touch back button, exits the Gallery app completely

Does this also happen in Safe Mode? https://support.t-mobile.com/docs/DOC-34097. How about if you go to Settings>Apps, select Gallery, and Clear Cache/Clear Data? (Don't worry, clearing the data from the Gallery app doesn't delete your photos -- when you open Gallery again, it will rebuild its database in a few seconds from the photos saved to your storage.)

OK, root cause found:
The default app for viewing videos was Google photos.
Apparently, after opening a video from the gallery and hitting back button, the Google Photos couldn't go back to the Gallery.
Once I changed the default video viewer to native Video app, I can easily go back to the list.

Thanks for the hint on clearing the cache, I started with cleaning the default apps and it resolved.
