When it comes to updates of the Android operating system, they have been a little slow to rollouts. This was especially true of Android 5.0 (otherwise known as Android L or Lollipop) and there have been a lot of devices that still don't have the latest, Android 5.1.1. Now that the Google I/O Developers meeting brought Android 6.0 into the world, users of phones like the HTC One M9 and M8, as well as the LG G4, G3, and G2 are wondering about their Android Lollipop 5.1.1 and Marshmallow 6.0 updates.
The HTC One M9 and M8
One thing that is for sure, it is expected that Android 6.0 will be coming to the HTC One M8 and the HTC One M9, according the ultimate developer preview regarding Android M that was released by Google. The issue is no one is certain when, as the Sense 7 User Interface was supposed to hit the M8 by now, and never did.
Like many Android phones, the M8 will probably skip the Android 5.1.1 Lollipop. In fact, this device doesn't even have Android 5.1 yet, so HTC One M8 users can probably count on a decent wait time before Marshmallow comes to the M8.
As for the HTC One M9, only those that possess the Developer Edition have Android 5.1. The news about releasing the latest Android 5.1.1 version on every edition of the HTC One M9 has also not been made public. It is possible that it will just skip the Android 5.1.1 for 6.0 Marshmallow.
The LG G4, G3, and G2
According to Neurogadget, LG hasn't revealed when its newest flagship device, the LG G4, will receive the update to Lollipop 5.1.1, and the same applies to the LG G3 and G2. It looks like that LG is probably going to pass up the 5.1.1 and go straight to 6.0.
This rumor has also been reported on a separate article from Neurogadget, as there are a lot of cues that reveal that LG might be passing up the Android 5.1.1 Lollipop update for the LG G series of smartphones and just "wait it out" until Android M gets released. This actually makes a lot of sense from a business standpoint, but from the point-of-view of a typical user of the LG G4, G3, or G2, it means a lot more wait before they receive the latest version of the Android operating system on their device.
LG has skipped other Android updates in the past such as Android 4.4.4 KitKat and Android 4.4.4 KitKat. This is different than what Samsung does, which is consistently update its devices with the latest of Android versions, even though the rollout might be slow.
As far as the older models of LG phones are concerned, it would appear that the LG G4, the most recent version of the G series of smartphone was lucky enough to come with Android 5.1 out of the box. However, even this phone, which was just released this year with that recent version, probably won't get Android 5.1.1 but wait for the Android M. There is news that there is a way to extend the battery life on the G4, according to Android Central.
G4 and G3 owners will get their latest update to Android M even with the wait. However, those that are using the LG G2 might not even get Android M, but it is possible that you could receive Android 5.1.1. In fact, there is a report from GSM Arena saying that the LG G2 could be on its way out.
