A recent commit for Google Chrome suggests at least 32 million Android devices won’t be able to use the mobile browser soon. The API level for the Chrome mobile browser will be raised from 4.1 to 4.4, so this means those devices that still run on Android Jelly Bean will not be able to use Chrome. Based on the latest figures, Jelly Bean is still used on 3.2% of Android devices and if there are roughly one billion phones and tablets using Google’s open source mobile OS, this means it can possibly affect 32 million devices. But then again, it might be time for an upgrade. Android 4.1 Jelly Bean first came out on July 10, 2012, while the first stable version of Chrome on mobile came out on June 27, 2012.
