iPhone X doesn't vibrate UPON switching to silent

Today i had this problem. You need to go to settings -> sound and haptics -> and make sure vibration set to ON on both silent and ring. On my iphone x it was switched to OFF somehow , i have no idea how.

For you to feel the haptic response for switching the phone from Ring to Silent, using the Mute switch on the side of the phone, the setting for System Haptics has to be turned on. This should be the final setting in the section on Settings>Sounds & Haptics. Even with the two settings you mention, for vibrate, it won't work if System Haptics is turned off. It is not a true vibration, but a haptic response when the switch is turned to Mute.

I have the same question. Currenty i'm seeing some notifications coming from a group chat. Even though I'm touching the phone it's not vibrating. It's almost like Do Not Disturb mode. It vibrates on my pocket when I have a call though. strange.

I’m experiencing the same issue. I think that there is a manufacturing defect with the ring/silent switch. I reached out to Apple support and after some troubleshooting they advised to schedule a Genius Bar appointment... I will report back on this when I have more insights.

When it comes to the feedback when switching the Mute switch to silent, it is not a vibration like you were used to with older phones. It is more of a haptic feedback, and is a very short one.

Make sure in Settings>Sounds & Haptics, that you have System Haptics turned on. That is what controls that haptic.

I had the same problem with all settings correctly set up. The problem was resolved when I erased all settings (do not erase content) under Settings - General - Erase. This will mean that you have to modify settings to your preference again, but at least it worked out the missing vibrations for me.

You're welcome. How it worked in the past had to do with the fact that all the phones had was the vibration motor, so you got that, based on the fact that you also had a physical home button. Now, with the changed home button in the iPhone 7, and above, the phones have the haptic systems in addition to standard vibration. So, for system settings, it is a haptic, and requires the setting for System Haptics. Also, I just tested my device with System Haptics ON, and I do not receive a haptic response when I take a photo with the camera. So, if that is the only thing concerning you, it may be a moot point, since taking a photo does not appear to generate a haptic response.

Under Settings, Sounds & Haptics, what is the setting for "Vibrate on Silent"?

Try following this ...it worked for me

I had my vibration switched off any general setting

Apparently the default on my iphone X under Ringtone/Vibration was set to None. Very annoying! Thanks for the link.
