I have an S10 5G. I want the phone to vibrate when I receive a call or text. When I receive voice calls, the phone vibrates as it should. When I receive text messages, it doesn't vibrate. From what I see in the Messages Notifications and the main Notifications areas, everything is set properly. Am I missing something or is this a known issue?
It actually does vibrate when it is ringing for a voice call. Just not text messages.
The reason you do not have the vibrate while ringing option is because when you toggle the ringer to vibrate instead of ring; it disables the "Vibrate while ringing" toggle. If you were to toggle your sound mode, you'll see that option.
You might wanna try clearing the cache if noth your message notifications are all toggled on, and your volume and vibration settings are all set. That would be the only thing left that would cause that issue.
