Do the vibrator and speaker work normally when the phone is on?
Check your phone's sound profile to see if you have disabled the vibrator.
Yes sirDid you try to enable "Vibrate on touch" to see if it works ?
As I am usng 3 other smart phones of same company MICROMAX and even my friens are using diffrent company smartphones like MOTO,Lenovo,etc.So back to the original question, what makes you think that your phone must vibrate while powering off and makes a sound while powering on?
means there is no problem with my phone??????????????Just make test with my Lenovo K3 Note, it does vibrate while powering off but it doesn't make any sound while powering on.
Ohk sir Thank you very muchAnother test with my LG G4 Stylus, it makes sound while powering off and on but it doesn't vibrate.
So I think your phone is perfectly fine, different firmware versions can give the phone different features.
You're very welcome.Ohk sir Thank you very much
thanx for giving attention and your precious time to my problem
