Its been like 6mos i think, since my phone is not vibrating. I tried to check *#0*# but still not.Tried to restore also but nothing happened. Sometimes its working, but very rare. Means, vibration is working, maybe something in the system is stopping...
this usually happens to my Samsung A70. It will come & go.
Last week its not working, then again it works.
But now, its NOT working again.
I have restarted already but maybe everytime my phone updates, it'll not work.
