Unofficial Android updates, custom ROMs and misc. hackery

  • Moto X: A test build of Android 4.3 for the Moto X on T-Mobile has worked its way into the wild, which is said to improve camera performance. Overall system speed is degraded, however, and the software is described as far from complete. [IntoMobile]

  • Samsung Galaxy S 4: A new utility known as Safestrap is available for the GS4 on AT&T and Verizon, along with the Galaxy S4 Active (AT&T), which allows users to run custom Android builds within a virtualized environment -- thus leaving the stock system intact. Safestrap is still in early development, however, and use of the software comes with more than the normal list of precautions. [Android Central]
