Finally, I updated my Samsung Galaxy S4 GT-I9500 to XXUBMEA firmware. Based on SamMobile, there is lot of interesting new features in this update (for both I9505 & I9500). Too bad that I cannot receive OTA update or using Samsung Kies to upgrade because I am using custom kernel. Therefore, I need to install XXUBMEA firmware with Odin manually. Wow… Can’t wait to test out all the new features. Did you update?
