I am running unrooted Android 4.1.2 XXELLA firmware. Personally I have not encountered this issue on my SGS3… Yet….
In any case, on looking for the data/clipboard, I could not find it. Is this a folder that I will see only if I root the phone?
Also in the keyboard on opening the clipboard icon, I have an option to delete the contents. Will clearing the clipboard in this manner suffice to stop this bug?
