How do you do this?
Need to update my PS4, is the remote play 60fps on the Xperia Z3 also?
Maybe it has to do with the new firmware where you can remap any button on the OS level. The PS4 has this now, maybe the Vita got it too?
Hold down the ps button, go to settings then controller settings and assign buttons? This has always worked for me on the Vita even before the patch.
