How do I find untagged photos in gallery app?

[prb456]

How do I search for photographs I have NOT tagged? I want to make sure that everything is tagged, going forwards.

I'm trying to do this on my phone using the baked-in Gallery app, is there another app that will allow me to do this?

Or should I just download everything to my computer and is there a Windows program that will accomplish this for me?

I have a Samsung Galaxy a.50 running Android Pie.

TIA! I'm a tagging newbie.

What do you mean by 'tagged'? If you enable photo backup, they'll get backed up.

You should also download anything you don't want to lose to your computer. ("Too many backups" is a nonsense phrase.) Copy the /DCIM folder to your computer - that should back up everything. If you have a /Videos or /Screenshots folder, copy them too.
