PS4 1.7 Firmware Update Causes DualShock 4 Vibration Malfunction: Workaround Found
The 1.7 firmware update for the PS4 introduced several welcome features, but also quite a few glitches, that hopefully will be solved with version 1.71 which is rumored to be coming soon.
One of those glitches causes the DualShock 4 to stop being quite so shocking, or to be more precise it leads to its vibration being turned off by default when you fire up the console, regardless of what you have set it to (it will still appear active in your settings, it just won’t work), as reported by Reddit user BrockLanders17.
I could easily replicate the glitch on my own PS4, and verify that it does indeed happen.
Luckily, there’s a very simple workaround for the glitch, so that you can get your vibration back until Sony solves the issue. Hold the home button to bring up the home menu, select Adjust devices and then Turn Off Device. Finally press the home button again to turn the DualShock 4 on again, and it’ll vibrate again.
Unfortunately this is just a workaround and not a full fledged solution, as the glitch will rear its head again every time you turn the console on, and you’ll have to repeat the process, but it’s better than nothing.
