The Google Nexus is having its big announcement soon, which signals the first rollout of the new version of Android. At that point, the new version of Android trickles down to other newer Android phones, and then the next ones. 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 (otherwise known as Android M or Marshmallow) 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 M8 and the HTC One M9
According to Neurogadget, the HTC One M8 will receive the Android 6.0 Mashmallow update soon after Android M gets released this fall. The confirmation of this comes from Mo Versi, who has become the product spokesman for HTC when it comes to Android updates and their flagship smartphones. Since the HTC One M8 is receiving its share of Android 6.0, then it shouldn't be long before the newest phone, the HTC One M9, will receive its update as well.
As for when HTC's flagship phones will be getting an update to Lollipop 5.1.1, the answer to that is probably not. It will more than likely skip that phase and move into the newest, but it is not known when that release date will be.
The LG G4, G3, and G2
In another article from 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.
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.
