Playing on PS4- is it really better to get a USB keyboard?

[Llamaskull]

I DO have a Nexus 7 and the PS app- I'll give that a try, too. I hadn't thought about the fact that it has a keyboard! Thanks!

UPDATE:
So I used the PS app on my nexus 7 and it does work as a keyboard, but if you're not using it heavily the connection will time out after a couple of minutes. It'll do in a bind but I went ahead and ordered a regular ol' USB keyboard. If I get it on time I'll be trying it out tomorrow.
