Hello!
My phone has really noisy vibrations for notifications (texts etc), when I go to the vibrations/haptics settings and turn the thingy up then down it resets and is once again less strong/noisy. But the next day it is back to being too noisy (although nothing changes in the settings - it’s constantly set to the lowest vibration level) 
has anyone else experienced this? 
Can you share a screenshot of your settings? Most people find vibration too weak. Do you have touch feedback enabled? This seem to have influence on the notification vibration
Thank you for your reply! I do not know what “touch feedback” is translated into in the Swedish version could you tell me where that setting is located (If it’s not in the pic)? I have turned off the keyboard vibrations, if that’s what you meant?
Its Tryckaterkoppling… Maybe try to also disable Vibration for mediA
I’m not sure which part is the one bothering the most.
You have low values for notifications and disabled keyboard vibration and touch response. I have it default and never found it too strong, sometimes even too weak.
Have you tried to change the setting and then reboot?
Some settings are lost on reboot but maybe this one stays
