Keyboard support on Android TV

[tiryn]

Hello,

I'm currently using my LG TV's webOS 3 and while it's not bad I'm disappointed there's no consistent keyboard support in a lot of the apps like Amazon Prime, Youtube etc...

It really makes searching for content or logging in a pain!

I'm wondering is this any different in Android TV apps? Do some support some don't again?

Is there perhaps voice search in everything even Prime and other non-google apps?

Thanks
