As we've said above, Nougat is only on certain Nexus devices and the LG V20 right now. Nexus phones and tablets are always the first to get new operating system updates, but even Google won't support them forever. Security updates are provided for three years following the device's release, or 18 months after it is removed from the Google Play Store (whichever is longer).
So, for example, the Nexus 5X and Nexus 6P will be supported by Google until September 2017, which means they will get both Android Nougat and next year's Android O. The Nexus 9 and Nexus 6 will both be supported until October 2016, which should mean they get an update to Android Nougat but not Android O. Older Nexus devices will not be upgraded.
Those with supported Nexus devices should find the update rolls out to their device following the launch of the new Nexus phones for 2016, or at least within a few weeks of launch. Also see: How to direct reply in Android Nougat.
If you have a recent flagship phone or tablet from a well-known maker such as Sony, Samsung, HTC, LG or Motorola, it's likely you'll see the update rolled out within the first few months of 2017. However, before you can get the update both the hardware manufacturer and mobile operator must be ready to roll it out, which can slow down things.
Sony has already confirmed that its most recent Xperia devices will get Nougat, including the Z3+, Z4 Tablet, Z5 series and X series. However, the Z2 and Z3 series will not receive Android Nougat.
HTC has also confirmed which devices will get Nougat, quoting the HTC One A9, HTC One M9 and HTC 10. It has a 90-day guarantee, which means those devices should get Android N in Q4.
Motorola says its Moto Z and Moto G4 families will get Nougat in Q4 2016.
It's telling that even a year and a half after its release, Android Lollipop has only recently become the most popular Android operating system. Often only the most recent flagships get an update to new Android operating systems (also see: How to update Android), and even then nothing is guaranteed. With thousands of people still using Android phones that are entry-level models, from less well-known manufacturers or simply old, there are still people out there running Froyo and Gingerbread - and they will never get an update to Android Nougat.
For performance Google is focusing on graphics and runtime in Android Nougat. It has introduced the new Vulkan 3D graphics API, which has a much lower CPU overhead than OpenGL and allows developers to squeeze much more graphical detail into frames. It's also introducing the JTI Compiler, which speeds up app installs by 75 percent and reduces the compiled code size by 50 percent.There are also new platform features aimed at optimising battery and memory consumption, such as Doze and the new background optimizations.For security Android Nougat introduces file-based encryption, media framework hardening and seamless updates. The latter means new updates to the operating system will be downloaded silently in the background, ready to use on the next restart. Unfortunately, seamless updates are likely to be available only on phones sold running Android Nougat out of the box - it works by each phone having two system images, and one is updated in the background while you use the other. Today's phones, of course, have only one system image.
Spending a bit more, around £500 and above, will potentially get you a nice laptop but it's likely to have an entry-level set of specs. We're talking a relatively basic processor, minimal SSD storage and a low resolution screen. It might also be a bit heavy and bulky.
Ramp up the amount you're happy to splash out - £800 and up - and you'll be looking at the best of the best with a blazing fast processor, plenty of RAM, hordes of storage and a gorgeous display. You should also expect excellent build quality and premium materials.
That's why it's crucial to read laptop reviews before you buy.

Best laptops 2016: What screen size do I need?
The size of your screen is an important decision when buying a laptop. After all they typically range from 11- all the way up to 17in.
A smaller screen might be harder to work on but it means that the laptop will be far more portable, handy if you need to take it around with you wherever you go. Bear in mind that a smaller device means less space for features like ports.
At 17in, you're buying a desktop replacement laptop which isn't deigned to be moved around often. You'll likely get a full-size keyboard, lots of connectivity and possibly even an optical drive, too.
Generally, unless you're looking at either end of the spectrum, a 13in laptop is the sweet spot for us combining portability with usability.
While many laptops have a resolution of 1366x768, you should look for something more if you want the best. Full HD (1920x1080) and higher should be a tick box and you can even get 4K laptops now, although arguably it's not necessary.
If you want a touchscreen, this normally adds to the cost. Most laptops come with a glossy screen but most people prefer a less reflective matt finish so that's something to look out for, too.
Best laptops 2016: How much storage do I need?
As usual, storage depends on what you want to use a laptop for. As a general rule of thumb get as much as possible without wasting money on the upgrade (manufactures can charge a premium on this area).
An SSD will mean your laptop runs faster but doesn't provide as much space as a traditional hard drive. Remember that there are also plenty of cloud storage options but this isn't so helpful when you don't have an internet connection.
If you're going to need to storing a large amount of data (perhaps you make home videos or you simply want all your TV box sets ready to go) then look for 1- or 2TB of space. Don't forget you can buy a portable USB drive to supplement a laptop which has only a small-capacity SSD.
Memory (RAM) is where programs and files are stored only while you're using them, and more is always better. Consider 4GB an absolute minimum, unless it's a Chromebook, with 8- to 16GB the ideal figure if you can afford the upgrade. You can't have too much.
Best laptops 2016: Which laptop processor is best?
Unless you're going to run complex and demanding software or gaming, you don't need the latest top-spec processor. It doesn't hurt, of course, but it's best to find a nice balance as there's nothing worse than waiting for a app to load etc.
If you're happy to splash out then you're probably looking at the latest generation (6th) Intel Core i7 chip. Entry-level spec models are likely to offer a Core i3 or even a Core M processor instead. A Core i5 sits nicely in-between so check how much extra it is to upgrade before making a final decision.
If you're not sure which generation the Intel processor is, look at the model number as the first digit represents this. For example, a Core i5-6500 is a sixth-generation CPU.
While most come with Intel processors, you can still find AMD powered devices around. See AMD vs Intel for more information.
Best laptops 2016: Ultrabooks and ultraportable laptops
Buying an ultraportable laptop is really no different than any laptop, except that your priorities are likely to be different. You might want an ultraportable laptop that's light and will last a long time away from the mains.
However, other people want an ultrabook that's powerful and can handle demanding applications without breaking your back when you carry it around. Both types are available.
Some compromises are inevitable if you want a thin and light laptop, though. There's less space for a battery, so it's typical to find shorter runtimes. But some companies have overcome this with clever packaging, such as the MacBook Air.
Another factor is efficient hardware, so a newer processor is likely to sip rather than guzzle power. The same goes for other components. But you should always read our reviews to find out how long a particular laptop lasted in our tests as you can't rely on specifications and it's unwise to go only by manufacturers' claims.
