Android 4.4.1 ? Oh, that’s so old hat. If you’ve got a Nexus device, check for updates now because the new Android 4.4.2 update is rolling out right now.
So far, all we know is that the new update includes a fix for clearing the voicemail indicator, some “security enhancements and “various software fixes”. If you see anything else do let us know, and if you’ve got the download give us a shout too :)
