Are you using beta versions of Signal? - lemm.ee

I just want to be able to regulate the vibration intensity or pattern. Signal vs. Snapchat for instance. Quiet ish vibes vs. an earthquake. I think they had that feature a long time ago in android 7 or something like that.
Maybe you should change system wide intensity setting or keyboard setting?
The system wide setting only goes as far as turning the vibration on or off. As far as I can see there’s no way for me to regulate it.
On stock Android (LineageOS) you can configure it in accessibility settings.
