My Sony z3 has stopped vibrating....pls any one with a solution
Hi @ADEWUSI, welcome to our community!
I'm sorry to hear about your phone. 
Did you install a new application or installed a software update in your phone just prior to you starting to experience that the vibration was no longer working?
I would recommend that you start with doing the inbuilt test for the vibration in your phone which you can find in Settings > About phone > Diagnostics > Test > Vibration. If the vibration is not working in this test, try rebooting your phone in safe mode and redo the test when third party applications aren't loaded, so we can make sure that one of them isn't the cause of this!
Edit: You can also check so the STAMINA mode isn't active in your phone, this mode will turn vibrations off! You can find the STAMINA mode in Settings > Battery.
Let me know how it went!
Hi!
It's possible to keep the Stamina Mode activeted and have the Vibration function?
Device: Z3 D6633 Dual with Android 6.0.1
Regards!
Hi @EzioRossoJr, sorry for the late reply.
When you enable the STAMINA mode, vibrations will be turned off and there is no setting to keep vibrations on when the STAMINA mode is activated.
I hope that helps!
