SamMobile have gotten their hands on the new version of Android that shouldn’t be a surprise to anyone. 4.3 was expected to be announce at Google’s I/O this year, but they kept quiet instead. The new update build that has leaked for the Galaxy S4 Google edition is installable on a regular Galaxy S4 i9505 thanks to the port over on XDA. This does require some flashing knowledge and could be harmful for your device if you aren’t sure what you are doing.
The installable version is said to be working flawlessly with no notable bugs. Check out the link below for more information on Sam Mobile or to install it with the XDA link.
