Android 4.4 Kitkat is out on Nexus 5. As we know what’s new on Android 4.4 Kitkat, everyone is looking forward to get Android 4.4 kitkat on their smartphone. So do I. Thanks to the xda developers who has extracted Android 4.4 Kitkat launcher from the latest Nexus 5. You can now try Android 4.4 KitKat launcher in any device with Android 4.1.2 OS and above. Bear in mind, you may see compatibility issue or force close because the kitkat launcher here is not official for your devices. Great news is that some of you has been tested the launcher and confirmed to be working on specific OS and specific device. Your device warranty may void with any mod. Check your devices warranty’s term conditions before start. Nexus 4 users are in luck as Google will be officially rolling out 4.4 very soon but what about the rest of us that aren’t rocking a Nexus. It will be an easy couple of months before OEMs begin seeding this to their flagship handsets and God knows how long before it trickles even further down. Rather than ditch your ROM for custom 4.4 builds, there’s a quicker and safer option to satiate your sweet tooth
