One of the simplest ways to keep thieves or nosey friends from snooping in on your personal life easily is to take the time to first screen lock your phone. You don’t want to make your phone an open book to anyone who walks by it, especially if you got one of those new Nexus 7 Tablets lying around, so be sure you have a lock setup whenever you leave your device unattended.
You can lock your device according to OS by using these instructions.
Android: Go to Settings > Location & Security => Set up screen lock. The timeout delay is configured separately, under Settings => Display. It also offers a connect-the-dots swipe pattern instead of a PIN or password, but it may leave smudges on the screen which make it easy to figure out.
BlackBerry: Go to Options => Security Options => General Settings >Password
iPhone: Go to Settings => General => Passcode Lock
Windows Phone 7: Go to Settings => Lock & Wallpaper.
Self-Destruct For The Win
In situations where you can’t find your device and someone could have taken it without you looking, then remote locate, lock, and wipe is your next best friend. With remote locate, you can find your device much like GPS operates and you’ll be able to figure out if you truly lost your device or if its somewhere half across the world in a place you’ve never been. If your device was taken, you can lock it remotely and also choose to wipe the data clean if you don’t see a retrieval possible. You may have lost your phone but at least by wiping it, you can prevent your personal life from going viral across the web. Depending on which OS you have, you can download or access these features quickly and easily straight from your device.
Save The Data!
One of the most important things you can do to secure your data is to always have a back-up stored somewhere safe. By backing up or syncing your data, you can recover it whenever you lose your device or even if it breaks that time when you dropped it off your 3rd story apartment. You can’t always guarantee a recovery after your device becomes lost or stolen, but you can guarantee you’ll be able to recover your data if you back it up. Many operating systems offer cloud services to back-up and sync your data so you never even have to touch a cable since it’s all automated.
Update and Turn Off Bluetooth Discovery
Thieves and criminals are always thinking up new ways to take what’s not theirs, so to keep your device from becoming easy pickings, always update to the latest software. Doing so will help prevent security holes and any bugs from affecting your privacy. Also don’t forget to turn off Bluetooth discovery to prevent any unauthorized access to your device and so others won’t detect your device nearby.
