Maximize Available Device Storage with Cassini
Storage space isn’t quite as much of a problem nowadays compared to before. Phones and tablets are being pushed out the door with some comfortable internal memory specs such as up to 64 GB. This is even more true if you insert a sizeable MicroSD card on expandable devices. That said, not all OEMs include external storage or large caches of internal storage, so some owners who enjoy a considerable music library or movie collection continue to be bothered by the ‘low internal storage’ notification.
Although not a miraculous instant fix for those suffering such woes, XDA Senior Member divinemamgai‘s Cassini may alleviate the situation to a certain degree. A PC-based tool, Cassini minimizes the size of the apps you have installed by compressing the app’s image files. This results in less space used up by apps, and more space for your photos, music, and movies. According to divinemamgai, all system apps except for LatinIME.apk will work with Cassini, while some apps from the Play store will be compatible such as ZPlayer, Textra, and Solid Explorer.
Before installation, a brief setup process is required, including running Java 7, creating a new system variable, and editing your path—nothing complicated. With this, you’ll be able to install the tool and be on your way.
