Reset option on Android phone doesn't work as advertised



In most cases, consumers whose phone develop software issues have to resort to resetting their phones, before which they’re asked to back up data. However, for someone like me, whose week-to-week task involves moving from one device to another, it’s a source of making sure all personal data and belongings are removed from the respective device.

But looks like we’ve been barking on the wrong tree, as recent findings suggest the reality of reset option is different from what we believe. According to theory established via Security Analysis of Android Factory Resets’ by Cambridge University, over 500 million Android phones are under risking of carrying data that should have been erased in first place.

The researchers forming part of the team have come to this staggering conclusion after testing out over 21 phones that run on Android versions between 2.3 (Gingerbread) to 4.3 (Jelly Bean). The resulting assessment gave them access to old SMS, email, pictures and contacts that get saved up on Facebook or WhatsApp database
