Some time back I was asked by the PHOTOS app to move photos to my account. When I confirmed the same I have found to my dismay that they have been removed from my albums in gallery. Now how do I retrieve those photos back to my albums
Verify the photos are on your google account by going to https://photos.google.com. (sign in if needed) then verify they are there.
If they are then:
Go to accounts and sync. add account. allow 5 minutes to sync in background. open accounts and sync and sync now by hitting menu or 3 lines/dots and hitting sync. Update/install google photos app and then open it. change account under the google photos app to correct account if needed. See if photos are there, if not, after checking wait 3 minutes and check again.
Another option is too use the website to download all the photos to your sdcard by clicking on the "photos" section and then hitting the 3 dot menu in top right and hit "select photos", select the ones you want, then 3 dot menu again and hit download photos.
