I am trying the General Test menu code on my S3 and it Doesn't work. Any code I try doesn't work.. It used to work when I first got the phone. Could the software update have something to do with it? I have 4.4.2... Thanks

It's working on 4.3. On 4.4.2 we didn't quite tested it. The firmware is also a deciding factor. :-|

Try this code *#0*# and test whether it's vibrating. If it's not take a backup and hard reset your device.
