You know Samsung has taken utmost care to raise the security features in its latest super phone, the Galaxy SII (see update below). Nothing comes ahead than the ability to track your device and have the ability to delete all your data when your phone is unfortunately lost.
Galaxy SII has built in Remote Controls (or Remote Functions in some phones) that you can use to:
Lock your mobile
Ring your mobile (irrespective of the mobile settings)
Retrieve Call logs
Wipe out all the data
Track your phone on the map (GPS will be turned ON automatically)
These 5 essential features are apart from the Sim restricting features such as alerting a pre-given mobile number (by you) when the Sim is changed or restrict outgoing calls.
While Galaxy S2 has maximum security features listed above, other Samsung phones, such as Galaxy S or Wave and tablets such as the Tab 10.1 and 8.9 too have some of the security features.
Of course, to use any of these features, you should (have) first setup your device. To do just that, you should create a Samsung account (go to Settings ->Accounts & Sync ->Add account ->Samsung account).
Once you have created your Samsung account, it will be linked to your device to manage remote actions.
Before you can remotely manage, you will also have to activate remote functions on your phone. Go to Settings ->Location and security and check ‘Remote Controls’ (or Remote functions). In some countries, this feature may be completely absent.
Once you’ve checked Remote Controls, your phone/tab is now ready to handle that mischievous thief.
Just login with the same Samsung account at Samsung dive and you can see all the things that you can do, and yeah, you can test all the things (be careful with wipe-out) before you enter the battle field.
Update: One can now register any Samsung Galaxy S series phones based on Android and use all of the above mentioned features.
