Smart Vibration application allows us to automatically switch mobile units to silent and vibration mode.
When it senses itself in a tight environment.
What are the different types of "tight environment" that it is programmed to sense?Â
Automatic switching to silent and vibration mode
This is a very nice and simple question. Please, follow this instruction and you will solve this problem. Because recently I face this problem and solve it so nicely.  Please, switch off your mobile and to open your battery and sim card also. Than you insert your sim card and to open your cell phone. Or you use to restore your cell phone and than switch on your mobile. Than please go to your ring tone sittings and here find where are the vibration option. switch off your vibration. Please Do not  stay on your mobile where in a tight environment. If you do this your mobile is senses less itself. I think you are understand to solve your problem. So, follow it. Thank you.
