I went on the Memo app one day to modify one of my memos. I then saved it and went on to mess around on the Google Chrome and YouTube apps. I went back to the Memo app after about an hour to check on another one of my memos only to discover that it had been replaced by a copy of an earlier modified memo of mine (This may have happened on an earlier date but I'm not too sure). On the next day, I modified another one of my memos and saved it only to find out that it would replace the memo that I modified on the other day. I tried rebooting my phone but it didn't work. I really want those memos back and I was wondering if anyone here knows how to fix this glitch.
