PS4 - how to use iPhone/Android as mini keyboardFollow

I don't know about everyone else, but with all this Zodiac Weapon "fun" lately, I find my self getting comfortable doing the grind with nothing but the controller, laying down maybe.
I've found the need for quick communications at times. LS says something I HAVE to respond to. Random dude asks if I want to team up (simple no, or yes maybe). Etc. I have to get up, find the wireless keyboard, sit properly, bla.

I've found using the Playstation App second screen option as a keyboard is the perfect solution!

1. Make sure you phone is synced to your PS4 (one time)
PS4: Settings -> PlayStation® App Connection Settings -> Add -> note Passcode.
PS App: Connect to PS4 - > enter Passcode.

2. Connect to the PS4 by touching 'Connect to PS4' on the phone's app

3. Select the 'Second screen' option

4. Touch the small keyboard icon on the top left.

When playing FFXIV, the keyboard only unlocks when you select the onscreen keyboard (Triangle button).
So select the chat box and press triangle, type away!

As an aside, this works perfectly if you're using a Vita like I occasionally do but are still on your home network. I'll occasionally be running a crafting macro and will slide the vita into my pocket while I do yard work. If someone needs something I can pull the phone out, too, and type away.

I'd give you that. Had FFXI on the 360 for a bit, LOVED that keypad. They have one for the PS3; need PS4 upgrade!
