If you are the owner of a Samsung, Sony or LG phone, among others, you may just have got your new update to Android 4.4.3 KitKat, but it seems like the Google operating system is in for another revamp already, with Nexus devices already having received an even newer version.
The Nexus handsets, which are Google's own smartphones, have been on 4.4.3 for some weeks, but most of the large manufacturers have only started to roll out their own version of the latest Android operating system in the last few weeks, and now they'll need to set to work putting their own spins on the new variant.
XDA forum members noticed the new software over the weekend, and it is thought that Nexus 5 owners are now starting to see it being rolled out, with the majority likely to have been fully updated within the next few days.
At the moment, it is thought that it will only be the Nexus 5 that gets the update, with TechRadar reporting that its own Nexus 7 device has yet to receive any upgrade to the new OS. This suggests that Google could still be beta testing the new version.
However, the full range of devices – the Nexus 4, 7 and 10 should all start to catch up with the Nexus 5 in the next few weeks, with owners of other manufacturers' devices likely to see the new operating system changes in the month ahead.
As for what we can expect from Google's latest update, the company has yet to reveal all of the changes, but an employee has confirmed that there are no fundamental factors that are likely to wow the average user.
They have apparently said that the main changes implemented include upgraded security patches.
KitKat has overall been branded a success so far, with its release having brought about faster multitasking, improved reactions to touch screens and a more immersive display.
