Google Android Device Manager was updated on Thursday with some bug fixes, performance improvements and one important update – the ability to set a call back button on the lock screen of lost or stolen phones.
The updated Device Manager still retains its old functionality whereby you can set a lock screen password and a custom message for your lost or stolen phones, but on top of that you can now add an alternative phone number that will appear as a bright green call button on the lock screen.
The important thing here is that you can set up this option before the device is lost or stolen and you can even set it up after the smartphone is lost or stolen by using the web interface of Android Device Manager or using the guest mode feature on your friend’s Android phone.
According to Android Police, the ones behind the call back button revelation, they have found evidence that in future the call back feature could be integrated with Hangouts.
The site explains that this feature could be useful in case the owner of the device doesn’t have access to another line or an alternative number on which the person who found the device can converse.
