So there is this thing that has annoyed me since my Galaxy S8. The default vibration pattern for notifications (when on vibrate mode) seems to be two short vibrations.
This is driving me nuts as I always have my smartphone on vibrate but I want it to only vibrate once, one short "bing" kind of vibration.
I tried several apps which allow you to control the vibration pattern, but they all seem to work only if not in vibrate mode or for older types of OS (< 8). Mind you that this is pretty much only about WhatsApp, as I dont receive many messages via SMS or anything else. Changing the pattern in WhatsApp does nothing (it keeps vibrating literally exactly the same), external Apps do something sometimes (sometimes 3 vibrations, sometimes 1, most often still 2 and nothing is really reproducible). Finally, Android itself does not really give you any control over vibrations unless I miss something.
I even had a look at the sourcecode which (if I understand correctly) hardcodes the vibration pattern fallback for vibrate mode and does not allow any changes.
I know that it sounds really stupid but this is such a big grind for me, that I even consider switching the OS, as it drives me insane. So if anybody has any help it would be much appreciated.
