Toggle between TouchWiz and vanilla Android on the international GS4
After the Indiegogo campaign to bring MoDaCo Switch to the Galaxy S4 raised more than double the intended £1000 ($1500) target amount, the first private beta build of the custom ROM is being distributed to backers via email.
Similar the HTC One version, MoDaCo Switch allows owners of the international LTE GS4 (GT-i9505) to seamlessly switch between TouchWiz and stock Android, effectively allowing users to run two ROMs on the same device. Even better, apps and app data are shared between the two ROMs. It's a pretty awesome way to try out the "pure Android" experience while keeping the ability to escape back to TouchWiz if needed.
Creator Paul O'Brien has emailed those who backed the project with download instructions for the first private beta build, and a public release should follow before too long. In the meantime, you can check out the video above for a quick demo of Switch in action on the GS4.
