Keyboard Randomly Misbehaving
I was typing in Notes when I accidentally opened Weather, though the phone may have done it itself, because when i returned to Notes it opened up the Lock Screen search bar and typed in "kangaroo" and something else, "ltd" or something. I tried to close the search box. Once back in Notes, it created a new blank note. i returned to my original note and it began to delete the last few characters of the last 3 or 4 sentences I had written, but not the entire sentences. Either before or while I was undoing it, it typed "4@". I undid the changes and restarted the device. I have had no more problems. Is it a problem with my phone, a bug in the OS or something else? Thanks.
