The image on the left is a message I received from Airtel on the 29th of December, 2012, suggesting that I should upgrade to Android 4.0.4 on my Samsung Android device and it says I should visit the Samsung India website to get the process going. This is interesting for a few reasons:
1. The device has not run stock Samsung firmware after 2010 and for a while in 2011. For the past year and a half it has only run various custom ROMs, mostly various builds based on CyanogenMOD.
2. As far as I know, Samsung India does not have my phone number registered with this device. In fact, I am fairly sure that I have not registered for anything with Samsung India regarding the phone. The phone has never seen a Samsung service center.
3. The obvious suspect is Airtel. The device resides on their network and I have the ‘My Airtel‘ app installed on the device, which has permissions to read phone state, identity, network and location details. It is fairly trivial for the app to gather the required details and suggest an upgrade.
4. The lesser suspect is Google. The phone has always been wired to a Google Account and from that point it can access the firmware number, mobile number, location, carrier details etc. But the message originated from the same source that Airtel uses to send other alerts. Unless there is a formal tie-up between Airtel and Google, this will not be possible.
If it can be confirmed that the Airtel app was used to trigger the SMS, it should give us a hint that Airtel is fairly serious about the app. The app is shown to be in the 500,000 installs range by Google Play and it has a decent number of 5-star reviews. If it now triggers firmware upgrade text messages based on the model/manufacturer, it will be another significant move by Airtel to move out of the ‘dumb-pipe’ trap that telcos are desperate to get themselves out of.
