I have tried several wired usb and wireless bluetooth (ps3) and dongle to no avail. Every single keyboard I try has me missing letters or double spacing when I can type perfectly fine with the same keyboard on ps3 and pc. Yes it does make you sound like a tard when this happens. Specifically /p almost always comes off as / instead. Very annoying. I really hope SE can fix this issue. I have gone into the settings on ps4 for key rate delay and so forth. Adjusted them up and down and still no help. One of the wireless keyboards I am using happens to be a logitech media board pro specifically made by logitech for ps3 but I read on sony website that it was compatible for ps4 and that they have no known issues with it. lol
