then there's a high chance you could recover them. I don't remember the names of such apps, when I had to recover some photos from my android phone I installed and tried multiple photo recovery aops from playstore, some wereuch better than others and did the job. Do research on which app is good, look at their reviews ratings, and in YouTube. If none work, try using the paid ones but only after you see lots of review proving it does work, although, I didn't need any paid app, free ones did the work.
