I factory reset my Galaxy j7 to get rid of some cryptomining malware that was taking control of my phone. Most of my files are backed up on the SD card I have installed, including all my photos. Upon restoring everything from my memory card and cloud, every one of my photos is blurry, tons of memories nearly ruined. I've tried others gallery apps but everything is low quality. How do I get my photos back to their original high definition?
