Android M, or Android 6.0 Marshmallow, has been pushed to Nexus devices and introduced by HTC in its latest One A9 device. And soon the system software update will begin the rollout process for many more Android flagship devices, including the LG G3 in mid-December, according to a new report.

The latest news about the impending OTA rollout of Android M to LG G3 devices in Europe comes from a report out of Poland, picked up and translated by GSMArena. The report from Polish tech site Tablety states that the LG G3, last year's LG flagship, would begin receiving the Android 6.0 Marshmallow update in a rollout scheduled to begin in the region somewhere between Dec. 16 and Dec. 18.

The latest Google mobile OS update has already been released in a public OTA rollout to LG G4 handsets in the company's native South Korea, as LatinPost previously reported. Now it appears that LG is winning the Android 6.0 Marshmallow rollout race in general, as soak tests for the LG G3 were reportedly already underway, according to the Polish report.

There is good reason to not only believe the Android M update timeline for the LG G3 reported by Tablety, but to believe that LG devices in the U.S. won't be too far behind -- despite the fact that wireless carriers will have to first modify and test Android 6.0 Marshmallow before an OTA rollout can be expected.

That's because in an update to the original report, LG Poland executive Jaroslaw Bukowski officially confirmed that the update is pretty much ready to go -- at least for Poland, which will be the first country to get Marshmallow on the LG G3. South Korea will probably be next in line, along with an expanded rollout throughout Europe.

Then, if LG follows the usual path for these OTA updates, it's just a matter of time, come mid-December, before LG flagships in the U.S. will follow suit.
