I posted about this a long time ago (here) and I also found some other old topic (here) about this but I still have this problem. For some apps, even though I disable vibrating for notifications in the notification settings (so in the settings of the app itself), my phone still vibrates. It’s just a short vibration, but I just don’t want my phone to vibrate for every message that I get. I have experienced this with Threema (
I also don’t get led notifications from Threema, not sure if that’s related), the standard Messages app, Signal and Email. Not sure about other apps because I don’t get many notifications besides messages. I know I can put my phone on do not disturb/priority mode, but I don’t understand why the settings within apps are not working.
Update: okay I installed LineageOS (which is amazing by the way!) and I still have this problem haha? For Signal I now muted all my conversations seperately as a workaround but for notifications from Threema my phone still vibrates.
