I will stick with Samsung because their service is very convenient to me, quick and and close to home, it gives me peace of mind. But this notifications issue does leave me somewhat bitter, and also lack of haptic feedback while typing.
Dude you are a Samsung Wizard because your instructions totally fixed the annoying vibrations for my text messages and then I followed the same directions for my email apps and it worked too!! Thank you so much for figuring this out because I couldn't deal with the nonstop vibrations, you saved my new phone from "accidentally" getting thrown in a pool haha!
Does not work for me at Galaxy A6, Android 9. Have this setting all time, all vibrations everywhere to off, but when I put slider volume of notifications all the way left, then I get vi ration. There must be a way of prohibiting vibrations whatsoever, right? Like in developer mode disallow disable this part of hardware. I would like that, I never want any vibrations ever. They are only good at waking me up, annoying me or make uncomfortable.
