I have noticed recently that my phone has problem with deleting words and keeping it that way. For example I will type library and than delet few of the letters so it be libr and instead of keeping the letters to be libr the phone will jump back to library and start typing after the letter y so it will look something like this libraryary. Hopefully I explained it correctly. I tried to clear the keyboard catch but that hasn't worked. I am using the stock keyboard that came with this phone.
