Following last nights update to what i believe to be the marshmallow update, my LG G3 now has a constant alert/prompt saying "Unfortunately LG keyboard has stopped". This makes the phone nearly unusable as I can't type or search. Every time i click ok, it pops up again a moment later. Doing a hard reset and factory reset doesn't help as it seems to just add the update at power up again. What can I do to get me phone functional again?
