Once a week, once a month, once every 6 month, once a year? Or do you keep all of your photos on there indefinitely? I try to clean out the photos once a month, back them up on my computer and hard drive.
keep everything on the SD card. keep internal memory for apps. As far as cleaning out the photos go through about once a week just to get rid of the bad ones
If it's a special day where I'm taking more than say 10 photos, then at the end of the day I'll go through all of them and delete the ones that didn't turn out so well.
Otherwise, I keep all my photos & videos. Even when I'm purchasing a new Micro SD card I transfer all the old photos onto the new one.
That's why we can purchase 256gb Micro SD cards Hoard all the stuff haha.
Smart cleaning in settings does basically the same thing.
Except possibly for Malware.
I hate extra apps like that as I remember with computers that they usually just added to problem.
I am not saying your apk is a problem. Just speaking from my experience
