FP5 does not give haptic feedback/vibrate in gboard

I really want by keyboard to give haptic feedback / vibrate when I press buttons. Just a tiny bit.
But my GBoard, which seems to be default, does not give it. I have enabled it in settings, but even when I set it to 100 ms there is nothing.

In the same category, my grocery used to vibrate on my old phone, when it had scanned a bar code. It does not on FP5.

To test it out, I found an app called Vibration Tester by “Firoj Multane”. It has some options to vibrate from 1 to 10 seconds. 1 second is silent but the others vibrate. But when I chose to vibrate in a pattern, anything down to 10 ms makes it vibrate, as long as repeat is on.

So I took it even further: I create a small app to see the code, because there are many ways to vibrate.
This deprecated method (time contains the number of ms to vibrate, language is Kotlin):

            val vibrator = getSystemService(Context.VIBRATOR_SERVICE) as Vibrator
            vibrator.vibrate(time) // Deprecated method

vibrates from 1001 ms but not below that.

So I tried implementing the pattern vibration API:

            val vibrator = getSystemService(Context.VIBRATOR_SERVICE) as Vibrator
            if (Build.VERSION.SDK_INT >= 26) {
                val amplitudes = intArrayOf(1, 0, 50, 0, 100, 0, 255, 0)
                val timings = longArrayOf(time, time, time, time, time, time, time, time)
                val vibrationEffect = VibrationEffect.createWaveform(timings, amplitudes, -1)
                vibrator.vibrate(vibrationEffect)
            }

which worked perfectly, although it feels like the phone always uses the max amplitude. But that is ok.

So to me it seems that FP5 does not vibrate when using the old API and less than 1001 ms is specified. But it is quite annoying as many apps still uses it :frowning:

I dont use Gboard normally and keybord vibration is the first thing I disable when I set-up a phone, however I just enabled it in my keyboard and it works perfectly fine in my browser, writing here in the forum. However changing to GBoard, I also have no keyboard vibration. I would suggest to contact support.

Hi! Did you happen to set up your phone, by transferring your data over from an old phone? When I got my FP5, I used a USB cable to transfer my data from my Xiaomi phone, to the FP5, and somehow in the transfer process, my vibration motor in general just would work for any reason. I could only fix it by factory resetting my phone, and not transfering my old stuff the convenient way.

I did not, however in general a good question for the OP.

I just learned that

If you turn on Touch feedback (Settings > Sound & vibration > Vibration & haptics > Touch feedback)

it works, so if this setting is disabled it overrules the GBoard setting.

Thanks @Dryhte

Edit: thats intended behaviour and no bug.
