not sure if this has happened to anyone else.. but my vibrate on my jolla has either disappeared or is very weak

iv checked settings and vibrate is on for everything. even when using pulley menu there is no vibration.. only when i quickly move up and down on the pulley menu i can feel a very light vibration...

is this fixable?

iv tried turning off and on the phone.. didnt fix anything

i think it all happened when i decided to explain the concept of the other half to my friends, took off my white other half and re-attached it and it asked to install the theme.. i pressed cancel.. and i think i lost my vibrate since then..
