SFR says in a blog post that the upcoming update was confirmed by LG. We heard that the South Korean company was testing KitKat on the Optimus G since January, but it looks like it will still take a while until the update reaches end users.
Currently running Android 4.1 Jelly Bean, the Optimus G is just a mid-end smartphone by 2014 standards. However, it’s still a nice device, and we shouldn’t be surprised to see it getting KitKat. After all, the Google Nexus 4 (which already runs Android 4.4.2 KitKat thanks to an update rolled out last year) is based on the Optimus G, having similar internals.
The newer Optimus G Pro will also receive KitKat, but we don’t know if that’s going to happen before the summer. We’ll let you know when we hear more on this anyway.
