While we are fond of sharing our location via Facebook, Google Apps, Foursquare and Twitter, but they are trusted so far as we blindly believe on the brand name. But what if I say your Android Phone is sharing your location? It’s a very scary issue when your phone is sharing your location without your knowledge. But yes it had happened, The Electronic Frontier Foundation has discovered an alarming issue with Android phones.
When your Android device running Android 3.1 (Honeycomb) or later is in Preferred Network Offload (PNO) mode, it automatically broadcasts the previous Wi-Fi networks it was every connected to. Anyone within your Wi-Fi range could furtively investigate the recent broadcasts and know exactly where you were based on the maps with your Exact real time movement, reports EFF!
PNO which helps extend battery life by giving Wi-Fi priority over cellular data could become that much deadly was never ever believed. Now let me explain you in simple language, how it shows your location. For example, if you were at Hardees or any other restaurant (company) which uses its company name (i.e Hardees 1) as its Wi-Fi name will happily help someone knows where you’ve been. By tracking the last few locations you’ve visited, they can actually track your travels and even your daily routine. This is something which would drive you crazy!
Google has been successfully emailed about this issue, the reply by Google to EFF is quoted below:
We take the security of our users’ location data very seriously and we’re always happy to be made aware of potential issues ahead of time. Since changes to this behavior would potentially affect user connectivity to hidden access points, we are still investigating what changes are appropriate for a future release.
