I have already put my phone on ' Silent All ' but for some reason it keeps vibrating, I have also, went to the settings and changed it to ' Silent All ' but it still keeps vibrating and i need to turn it off vibrate.

The quickest way - on the left side of your phone there is a button with up and down arrows. Keep pressing the up arrow and this will raise the volume up, or keep pressing down and you can set it to vibrate or silent. Also, you can change it from the menu. Go to Menu > Settings > Audio & Ringtones > Ringtone and there are all of your options here. You can go to Volume and set the volume, Alert Type and set if you want it to vibrate/ring, etc. I hope this helps, if you still have questions feel free to ask :)

That happened to me ! I had to go into settings, then reset settings. you won't lose anythinng. and if you haven't already changed your security pin or whatever it is 0000

I selected the vibrate option after downloading a silent ringtone and setting that silent ringtone to the the default ringtone when vibrate in on.
For a silent ringtone, just perform a google search

Press and hold the pound key (#) until it exits silent mode. 

Here is the original text from the manual of the phone:

"Quickly Switching to Silent Mode
Silent mode is convenient when you wish to stop the
phone from making noise, in a theater for example.
In Idle mode, press and hold the "#" key until the “Silent
Mode” message and the Vibration icon display...

To exit and reactivate the previous sound settings, press
and hold the # key again until “Exit Silent Mode” appears.
The Vibration icon no longer displays."

You can also download the pdf file for the phone's manual online by simply googling "Samsung x427m pdf manual."

Hope this helps!

i figured out how. on the volume buttons (on the side) you just keep pressing the down button even after it says vibrate., if you press it enough (consecutively) it will say silent all
hope that helped

By default, the silent profile has the vibration off. Go to settings-->Porfiles-->Choose Silent-->options-->Personalise-->set the vibrate alert On.If my solution solved your issue ,vote for me.

go to profile activate silent mode in the settings alarm mode vibrating

Go into the main menu
Sound settings or Alert Settings
There will be an option for alerts (text messages) you can then change it.

Keep holding down for 3 seconds the (#) Buttom. And it's fix.

After you read a message, always hit the return/back key to get you back to the main list of messages. This phone automatically returns you to wherever you left off last, so if you don't hit the return key, your last message read will be what is displayed when you hit your message key.

No, your phone is not defective, you need to change your settings.

In your menu, go to SETTINGS, then PROFILES. Scroll to the profile you are using then select EDIT. Under each profile you have the option to select how your phone handles any alert you receive (i.e. for calls, messages, texts, etc.) You have several options some of which are silent, silent and vibrate, vibrate only.

Personally I want my phone to vibrate when it's on silent so that I know I'm receiving a call or text. You can choose another option though.
