“Low on space: Phone storage space is getting low.” Uh-oh. This issue is easy to fix if you’ve rooted your phone, but what if you haven’t? Let’s take a look at the possibilities…
What’s the Big Deal?
Does it really matter if you run out of internal phone storage? After all, you’ve got an SD card that can fit gigabytes of data and applications.
Actually, yes; being low on internal storage causes problems. If you’ve got less than 25MB free, you won’t be able to install over-the-air updates to your system (including new versions of Android). Less than about 15MB, and you can’t sync emails, Facebook statuses, calendar appointments, and so on. Also, some applications can only be installed to the internal storage: Flash Player 10.1 and the AIR for Android runtime are two big examples of this, each weighing in at a hefty 10MB.
Rooting your phone allows you to move these applications — as well as various system files — to the SD card, freeing up plenty of space. In this article, we’ll look at what you can do if you don’t want to root it.
