Selling Your Old Android Phone?

Whether you donate or sell your old Android phone, you should make sure that there is no personal information left on it. C/Net has a great how to: http://www.cnet.com/how-to/the-best-way-to-completely-wipe-your-android-device/

But as I got to step three: Load dummy data, I thought 'How much dummy data can my phone hold?' About 12 gb, it seems. That sounds tediuos - what are the chances that I'll actually finish copying 12 gb of dummy photos to my phone? Where am I going to get that many dummy photo's? And aren't photo's going to automatically post to Google+? Agh.

Of course, there is the advice 'take a hammer to your phone' ... So I wrote an app to do it for me

Data Hammer

And it's free on Google Play:

Get it on Google Play

Data Hammer fills up your phone's hard drive with random bytes. I've tested it on our phones -

  • Nexus 4 running 4.4, both Dalvik and ART
  • Samsung S4 running 4.3

And it is tested in the emulator to be compatible back to version 2.2 Froyo.
