About a week ago when I picked up my Samsung s5 my color note app opened and my it just started typing, extremely fast. It was complete sentences but didn't make any sense. I tried everything and finally got the phone to power off. Now tonight when I opened my calendar it opened up a day and started typing again. I saved it this time and the message was "Hey guys are having problems. it will take a few weeks, so I'm sure it was not able, I will try" Any idea what is up with my phone??? What would be causing this?
