Even though some devices may have similar resolution screens, they don’t always display the same information from the same applications. One notable example is the Google Calendar on the Nexus 7, which displays information in text view. The Samsung Galaxy Nexus, which has a similar screen resolution, displays information in small lines. To many, this is not the best way to view your Calendar info. Now, there is a way to make the Galaxy Nexus show up as it does on the Nexus 7.
The mod comes in the form of a custom recovery-flashable zip. There are some peculiarities though. For instance, if you’ve updated your Calendar recently via the Google Play Store, you have to uninstall the updates, or the mod won’t work. As XDA Senior Member shaftenberg explains:
If you have updated the calendar via market before, you have to uninstall this update before flashing, otherwise you will see nothing. Android prefers the .apk in RAM (/data/app) over any .apk in ROM (/system/app) – that is a pretty normal behaviour.
In addition, there is a second Market version that syncs your calendar up to a year. You’ll have to clear app data in both the Calendar and Calendar Provider to make it work right, but that’s no big deal.
For additional details, go to the original thread. While the mod was originally meant for the Galaxy Nexus, it’s highly likely that this will work on all devices with 720p screens running AOSP-derived Jelly Bean ROMs.
