Hi everyone. I am the owner of a Samsung Galaxy S4 GT-I9500, with a 4.2.2 Android Operation System running on it. I've been expecting the 4.3 update to come for 4 months now, nothing. It keep on saying "Your operation system is up to date" I tried Knox but it didn't work as well, it doesn't recognize my phone. Further Information about my device: Model Number: GT-I9500 Android Version: 4.2.2 Baseband Version: I9500XXUBMG6 Kernel Version: 3.4.5-1083225, se.infra@SEP-89 #1, Thur Jul 11, 22:52:49 KST 2013 Built Number: JDQ39.I9500XXUBMG6 SELinux Status: Permissive. I tried also to contact directly with the samsung support, but my device is bought in Kosovo, Prishtina, and i have no idea where my device is made for, as long as there is no dedicated support to our country. Please help me out, this is so annoying. Thanks alot, Valmir.
