Google's latest iteration of its near-universal Android operating system will launch later today. Considering the long list of updates and new features that Android Marshmallow will bring with it, it’s fair to assume that hundreds of thousands of users will try to update their devices as soon as the official release takes place.
Just to let you know if your device will qualify for an upgrade, let's look at how manufacturers are reacting to the new launch.
When Android Marshmallow was first announced in August, Samsung reportedly earmarked the list of devices that will receive the Marshmallow update post launch. These are the Galaxy S6, S6 Edge, S6 Duos, Note 4, Note 4 Duos, Note Edge, Galaxy Alpha, Galaxy Tab A and the recently launched Galaxy S6 Edge+ and Galaxy Note 5.
However, a surprise deletion from the list was the Galaxy S5, Samsung's flagship phone before the S6 phones arrived. It was the last flagship phone that contained a microSD slot and a removable battery, and is still popular amongst Samsung's loyalists. Samsung has recently confirmed that more devices will receive the Marshmallow update in due course, so the Galaxy S5 is still in with a chance along with the Galaxy A series phones.
LG has also confirmed that its G2, G3 and G4 smartphones will receive Marshmallow, but made no mention of the G Flex 2 which was launched at Mobile World Congress in March this year.
Even though HTC hasn't made an announcement yet, several new devices like the One M8, One M8s, One M9 and the One M9+ will receive the Marshmallow update, thus bypassing the Android 5.1 update which was rolled out last month. As per a fresh leak, the list of HTC devices that will get the upgrade include Desire Eye, 816, 820, 826, One M9, One M9+, One ME, One E9 and one E9+.
Apart from these, Huawei's Nexus 6P and LG's Nexus 5X will have Android M pre-installed when they'll be launched later today.
As far as older Nexus devices are concerned, Android Police has confirmed that Marshmallow will start rolling out on October 5 to the existing Nexus 5, Nexus 6, Nexus 7 (2013), Nexus 9 devices. However, Nexus 4 (2012) and Nexus 10 have not been included in the list.
If you do not own a Nexus device, you will probably have to wait for an over-the-air upgrade to be made available before you can upgrade. This could take several weeks or even months. If you don't wish to wait for so long, you can update your phone manually by accessing files uploaded by Google directly on the Android developer website.
