Now that Google has released Android 6.0 Marshmallow, the big question is: When can Android owners download and start using it?

If you own a Nexus 5, 6, 7 (2013), 9, Player, or Android One, the answer is easy. Google is now sending out Marshmallow in stages, and depending on your carrier, you have access to it now or will shortly.

If you ordered the new Nexus 5X and 6P phones, Marshmallow will come installed on those devices.

But Nexus devices make up a tiny part of the Android market, so if you own a Samsung, LG, HTC, Sony, or Motorola, you need to wait till your handset maker and mobile carrier prepare the update for you. Let's look at handset makers first.

HTC

HTC tweeted a chart showing which of its devices will get Marshmallow, and a few will get it before the end of the year.

  • HTC One M9 (starting at the end of 2015)
  • HTC One M8 (starting at the end of 2015)
  • HTC One E9+
  • HTC One E9
  • HTC One Me
  • HTC One E8
  • HTC one M8 Eye
  • HTC Butterfly 3
  • HTC Desire 826
  • HTC Desire 820
  • HTC Desire 816

HTC noted that timing will depend on carriers and regions and said that it may add devices to the list.

LG

One of the more popular Android handset makers, LG is so far keeping quiet about its Marshmallow plans. It's possible to triangulate a bit of the company's Marshmallow roadmap by looking at T-Mobile's plans (below).

Motorola

Motorola says it is preparing Marshmallow for some of its devices, below, and will have more news on dates and more devices in the coming weeks.

  • 2015 Moto X Pure Edition (third generation)
  • 2015 Moto X Style (third generation)

Samsung

Samsung, the largest US Android handset maker, is keeping mum on its Marshmallow roadmap. Back in August, a company representative posted on the company's website, "We have no information as of now on the devices receiving the Android M. We will keep you posted for any updates." The company hasn't said much since.

Sony

Sony reports it is working quickly to push Marshmallow out to supported devices, below, but gives no definite dates. It intends to roll out Marshmallow in stages, and the arrival date will depend on region and carrier.

  • Xperia C4
  • Xperia C5 Ultra
  • Xperia M4 Aqua
  • Xperia M5
  • Xperia Z2
  • Xperia Z2 Tablet
  • Xperia Z3
  • Xperia Z3 Compact
  • Xperia Z3 Tablet Compact
  • Xperia Z3+
  • Xperia Z4 Tablet
  • Xperia Z5
  • Xperia Z5 Compact
  • Xperia Z5 Premium

Sony is running a limited beta program for Marshmallow, but right now it's for a handful of countries outside the US.

Except for T-Mobile, mobile carriers aren't saying much about Marshmallow.

T-Mobile

T-Mobile has posted a list of devices it expects to receive Marshmallow. It cautions that software updates are a "long process," as the work involves cooperating with software and hardware makers. It's no promise that other carriers will update the same phones, but if your LG or Samsung phone is on T-Mobile's list, your confidence level might rise a bit.
