In Android, apps can either run in tablet or phone mode. In tablet mode, you often get a split-column view, whereas in phone mode, everything runs in one column. What if you could pick which mode your apps run in, to maximize their usability and functionality? If you have a big-screened phone with an HD display, you have plenty of room fully take advantage of your screen space. With ParanoidAndroid, available for many devices, you can have this amazing flexibility. And because it's CyanogenMod-based, it's fast and flexible.
This is reccomended for the Galaxy Note, Galaxy Nexus, Galaxy S III, HTC One X, or any other smartphone with a 4.5" or larger display.
