My keyboard appears to be having a few issues. There is often a lag when pressing buttons - either it doesn't register ive pressed it for a good 10 seconds or ill be typing a word and it will freeze mid word. Leaving whatever button pressed larger on the screen. Going from letters to symbols is the same. 10+ second lag there. When i close a message or app with keyboard the app will close, keyboard remains in screen. Sometimes up to 30seconds. Also the back button - not in keyboard doesn't register its been pressed. Also taking up to 30 seconds to go back a page ect. This has been a issue since the last update. I have done a factory reset, issue still remains.
