If you like playing with your PS4 while sitting on the toilet, but really don't like missing your triggers, there are good news, as the combination between the PS4 firmware update 1.7 and the 3.15 update for the PS Vita made playing in remote play with a DualShock 4 a lot easier.

Now the Vita will automatically be recognized for remote play as long as it uses one of the accounts registered to the PS4, and multiple users can be logged in at the same time using the same DualShock 4 controller, so all you have to do is have your PS Vita set to a different account from your PS4's main account, then open your game on the PS4 normally, and then go anywhere you want to go with your Vita and DualShock 4.

Turn on the Vita, select remote play, and it'll automatically be recognized and connected. It won't have any input on the game, but that really doesn't matter, because you want to play with your DualShock 4 anyway.

Luckily the DualShock 4 has a longer range than remote play itself (at least in local wi-fi), so as long as your Vita will stay connected, so will the controller. The icing on the cake is that PS4 games look absolutely beautiful  on the old Vita's OLED, now with additional ease of use thanks to the PS4 controller, which incidentally is also lighter than the Vita itself.

Below you can see a quick video showing how it works. Now the last hurdle is the inability to do everything with a single account, but hopefully Sony will take care of that sooner or later.

One thing is for sure: this is gonna help a lot with the terrible grind to drop the twelve Atma pieces in Final Fantasy XIV...
