I just returned from a month long vacation, and went to transfer my photos and videos from my phone to my PC, and none of them are there! However, I can view all of them using Google Photos. Some pictures from the last couple of days are there, as well as screen shots and downloaded pictures. They are not in trash - only some that I deliberately deleted, they aren't synced to OneDrive either. I have plenty of space on the phone, and I did not archive photos in Google Photos. 

Please help! I can get my pictures from Google Photos, but the quality is degraded. I want to transfer the originals as taken by the phone camera.
