Alexa has been available on Amazon's Fire tablets for some time, but only the 10-inch version has worked like an Amazon Echo and let you say, "Alexa, tell me a joke" without having to press a button first.

And now, hands-free Alexa is coming to the Fire HD 8, which has been updated for 2018. Here's what's new:

  • Faster quad-core processor
  • Upgraded front camera (now 720p)
  • MicroSD storage up to 400GB
  • Hands-free Alexa

Amazon Fire HD 8: Price & availability

The new Fire HD 8 is available to pre-order right now from Amazon. The first orders will be delivered on 4 October.

You will also be able to buy it from Argos, Currys PC World, John Lewis, very.co.uk and littlewoods.com.

It costs £79.99 / US$79.99, the same as the current model, but if you want 32GB of internal storage rather than 16GB, you'll pay £99.99 / US$99.99.

And as ever, it's £10 more on those prices if you don't want adverts on the lock screen.

Something new is the Show Mode Charging Dock (see below for details). This has been available for a month or two in the US, but it's brand new in the UK.

You can buy the new Fire HD 8 and the Dock as a bundle for £109.99, which includes the 16GB version of the tablet.

Later this year the Dock will be available to buy separately for £39.99 and also works with the 2017 version of the HD 8. For those in the US, you can already buy it for $39.99.

Colour options are the same as before: Black, Marine Blue, Punch Red, and Canary Yellow.

Kids Edition

There's no waiting for the kids' version of the new tablet. This is also available to pre-order immediately, and will also ship on 4 October.

Pricing remains the same as last year, so it costs £129.99 / US$129.99 from Amazon.

The bundle includes the 32GB version of the new Fire HD 8 plus these extras:

  • Bumper case in blue, pink or yellow
  • Year's subscription to Fire For Kids
  • Two-year warranty which covers accidental damage

Amazon has updated the Fire For Kids interface to make it more intuitive and - soon - will add audiobooks so you no longer have to add them manually from your own Audible subscription.

Amazon Fire HD 8: Specs & Features

Amazon has taken the approach of not fixing what isn't broken, so you won't be able to spot a 2018 model from the 2017 version just by looking at it.

The changes are internal: a slightly more powerful processor allows Alexa to respond even if the screen is off (in standby mode) and unlike the 2017 model, hands-free Alexa works even if the tablet isn't connected to its charger.

The only other upgrade is a better front camera, which Amazon says is because it knows users want to use their Fire tablet for video chats and the old 640x480-pixel camera wasn't really up to scratch. The new one has a more sensible 1280x720 resolution.

Here are the main specs:

  • Fire OS
  • 8in 1280x800 HD IPS touchscreen, 189ppi
  • 1.5GHz quad-core processor
  • 1.5GB RAM
  • 16/32GB storage (microSD up to 400GB)
  • 2Mp main camera, support for 720p HD recording
  • 720p front-facing camera
  • 802.11n dual-band Wi-Fi
  • Bluetooth
  • 10 hours of mixed-use battery life
  • 314g

Show Mode Dock

If you have an Echo Show or Spot, you'll already know what Show mode is all about. It adds visuals to Alexa's responses, more often than not making them more useful.

For example, ask about today's weather and you'll see more details on screen, plus a forecast for the next few days.

It's the same on the Fire HD 8. You can enable Show Mode by saying, "Alexa, enable Show Mode". You don't actually need the Show Mode Dock: it's really for convenience.

It comes in two parts. The Dock itself has an adjustable hinge so you can get the right angle and comes with a mains power adapter.

The other piece is a cover which clips onto the Fire tablet and plugs into its USB port so it can charge via the two pogo pins on the dock. Magnets align the tablet when you put it in the dock and Show Mode is switched on automatically when you do so.

Show Mode is ideal for various things, from cooking a recipe in the kitchen to a spot of Karaoke in the living room: many of the tracks on Amazon Music have lyrics which are highlighted as the song plays.

In Show Mode you can use the 'Drop-in' feature to start a video call with a friend or family member with a compatible Amazon device, be that an Echo Show, Spot or another Fire tablet.

You can also ask Alexa to play titles from Amazon Video (you need to be a Prime subscriber to access this, though), and the Dock is a useful way to prop up the tablet for watching videos and keeping the battery topped up.

We'll bring you a full review of the HD 8 shortly.
