Google has rolled out a new update to Drive's Android app. If your Android device still runs Ice Cream Sandwich (Android 4.0), there's some bad news: the Drive app on your device will no longer receive any updates. "This is the last supported release of Drive for Android on all Ice Cream Sandwich (Android 4.0) devices," the change-log says. "Ice Cream Sandwich (ICS) users will receive no further updates to Drive on Android." As for other changes, now you can easily upgrade your storage plan in-app, add home screen shortcuts to your favorite files, and receive comment notifications....
