An estimated 32 million Android devices could very soon no longer work with the Google Chrome mobile browser. According to XDA, a recent commit revealed that the minimum API level for the Chrome mobile browser app will be raised from 4.1 to 4.4. That means that those still running an Android handset powered by Jelly Bean will no longer be able to use the most popular mobile browser on earth with over 1 billion installs on Android alone.
Android 4.1 Jelly Bean was released to the public on July 10th 2012. The first stable version of the mobile Chrome browser for Android came on June 27th, 2012.
