Why are my pictures still on the phone?

I wanted to clear all the pictures from my cell phone. I connected the cell phone to my laptop and dragged all the pictures over and deleted it directly from my cell phone.

Now the pictures are still completely on the phone. If I then connect the cell phone to the laptop again (because I thought it probably didn't delete it), the pictures are no longer on it. But the pictures are still available on the phone at the same time. Can anyone explain to me? I don't have an SD card in my phone.

I have a Samsung S7, which means an Android system.

Are you using the Samsung Gallery app?

Yes, the Samsung Gallery app.

I use the Samsung Gallery app.

Maybe there are still the preview images in low resolution in the cache (buffer). Maybe clear the cache in Settings> Apps> Samsung Gallery>.

It wasn't, but thanks for the idea.

See if they can find a folder with "thumbnails".
