Android : How to Turn off Sound and Vibration in Androids Keyboard

Iphone: If you set the iPhone to vibrate in silent mode, it still makes an audible buzzing sound that may bother or disrupt others. If you need your iPhone to stay completely quiet, temporarily disable vibration. You can turn off vibration when silent mode is on, off or both. Tap the button next to "Vibrate on Ring."

Blackberry:
Turning vibration on my mobile phone on or off

1. Find "Notifications" Slide your finger down the display starting from the top edge of your mobile phone. ...
2. Turn vibration on or off. Tap the indicator next to Vibrate to turn the function on or off.
3. Exit.

Without more specific information as to what model phone you have, I can only provide you with general instructions. Under 'settings' in your phone menu, you should see an option called 'profiles'. Highlight that and click on it, and you should be presented with several different profiles, such as outdoor, meeting, silent, etc. Once there, select one of them and click on it, then 'edit profile'. You'll have a host of different options now, and at least one of them should deal with "notification", where you can change it to 'vibrate and ring' or 'ring only'. Again, I'm not sure of the exact wording, but you'll need to change it to something besides 'vibrate' or 'silent'. When you're finished, click 'done' or some such, then 'apply profile' from the next screen. Make sure you apply the same profile name as the one you just finished editing. Hope this helps! :)

If you're missing incoming phone calls due to your iPhone not ringing, you may have accidentally switched the ringer to vibrate or silent, according to Apple. The switch on the left side of the iPhone turns off the ringer and usually sets your phone to vibrate mode, but if your iPhone's vibrate setting is also disabled the phone will instead be set to silent mode. When in the phone's sound settings vibrate mode can be enabled, and the ringer volume of your phone is adjustable.

Your phone may be set to either a silent or vibrate mode, which would not allow the phone to ring. Look in your phone's manual to find out how to turn off silent or vibrate mode.

select the setting vibrate then ring

You need to go to setup or configuration and change the ringtone. The silent ring is considered a ringtone. While it might be handy you miss a lot of calls. I have one phone that somehow keeps setting itself back to this or vibrate/buzz and until I notice that it has done this I miss a lot of calls.

You probably have silent mode on. Try pressing and holding the pound or the star key. One of those will probably release silent mode, so that whatever ring setting you have can be used.

Have you checked to se if your phone is on silent or on a vibrate mode? It is possible you switched it without realizing it, which would cause the phone to not ring during a call.

you have not mentioned the make and model of your set  possibly it could have been kept in a silent mode go to profile setting in the menu of your phone and check the ringer settings

you can actually move the button , on the top left hand side of your iphone, over the ringer volume, you will see a red or orange dot, this means the switch has you iphone in silent mode, I was stuck on this, until I found it is a actual switch, look at it closely, you can move it. So where you see the red dot, put your finger on it and move it the opposite way, and I do not mean press the button, I mean, flip the switch on it, then your phone will not be in silent mode anymore,,, this was very annoying, I hope it helps anyone that has the same problem.
cheers!
