What are some steps to take into account to protect an Android phone in case of theft?

Smartphones are everywhere now, before the market was dominated by Blackberry and Windows Mobile. These days more and more companies are adopting Android, Windows Phone and iPhone instead. People carry a lot of information on their phones, often confidential data that was distributed through email.

How can one protect from leaking this business critical data in case of theft? Meaning: remote whiping or encryption of all data on the phone so that a thief cannot access this data anymore.

  • You should also have a look on the OS itself. When it constantly backups your data to wherever (e.g. Google), the files are already gone when the phone gets stolen. I recommend to have a look at the Cyanogen Mod -- a open source, Google-free Android (including full device encryption).

Apps that can whipe data or more:

Email clients that encrypt your email:

    Lookout Mobile Security also works well for providing remote lock, wipe, locations and scream functionality. That's what I personally use. Commented Sep 4, 2012 at 18:02
