I have been experiencing a loss of current text message randomly after selecting a word given in spell check. Typically this occurs after I have much of a text message composed. Most of the text message is lost and the selected appears in the middle of some word and everything disappears. This is incredibly annoying and happens quite frequently. This needs to be fixed or I need to understand what I can do to prevent this. It also has happened to by sons who also use Galaxy S3. It did not start happening until after the last update.
There is a fix! I found it by trial and error:
I went in and tested in a text message and now it just replaced the misspelled word in question.
The JZO54K.I535VRBMD3 update released in late May/Early June 2013 seems to have finally fixed this issue. Naturally a few new ones were introduced, so caveat emptor, but at least autocorrect no longer wipes out giant blocks of text using the stock keyboard.
What is this new update you speak of? I haven't seen any new update.
