[Feature request] From messaging to calling in just a movement

[rajatkhanduja]

This is a feature request based on SIII advertisement. SIII, apparently, has the feature that allows you to switch from messaging to calling by just swinging the phone to your ear.

As far as I understand, it gets the mobile number on screen (if only one) and calls it. In case of more than one number, we could have an option of which one to call.

Might be difficult to make a generic solution for this. It is possible that we could take some open source dialer/messaging app and modify it for this purpose but otherwise, we'd need to create an entire app for messaging... And we can't modify the default ones because they wouldn't be compatible with other phones.
Any other suggestions?
