Photos lost

Anyone know how to retrieve?

You need to provide more information? Did you check bin? If not and only using Gallaery app I would guess you wouldn't be able to get it back

Did you back it up, example Google photos? One drive? Or just keep photos on the phone?

Hi @dimps Assuming you have checked recycle Bin? Have you searched in My Files as well as Google photos? Do you have synchronisation with One Drive set up? Are you photos not backed up anywhere else. I would recommend backing up photos and files, cannot really take the chance.

However if you cannot locate anywhere you might be able to recover using Data Recovery software,I cannot recommend any one myself though as have not needed this option but you see some information here https://geekflare.com/android-data-recovery/
