About Google Pixel 4 - Review, Specs + more After numerous leaks and even a rumoured review embargo, Google's new Pixel 4 smartphones are now here: specifically there are two, the Pixel 4 and Pixel 4 XL. Both smartphones have been unveiled by Google recently in New York and pre-orders are now possible in the UK. So, what has changed from the previous generation - the Pixel 3A? Well, quite a lot. For the first time, Google has installed not just one, but two camera sensors on the back. how this changes the setup, and what other new features the Pixel phones bring, we describe in our early preview here - we will update this review after we get to test out the Pixel 4 ourselves in our hands-on. Summary of contents Pixel 4 - Design A selection of new features Now with radar?! Pixel 4 in the UK - Pricing, Contract cost Pixel 4 - Design The Pixel phones are pretty much known for their classic design ethos witnessed most clearly on the back, consisting of part glossy and part frosted glass, but that's been replaced with the Pixel 4. Google has adopted with these models a uniform glass back, which is available in either black, white or more recently orange, which Google calls "Oh So Orange". It doesn't actually appear to be that "Oh So", though - a website here has tested the orange colour against other famous orange items, and it looks rather dull in comparison. That said, we love the new orange colours available on handsets coming out right now and it certainly makes a change from millennial pink / rose gold. The aluminum frame is black on all models. The back feels very high quality in the hand, as per our testing at the Google event. While the black version shines, the other two variants are dull due to a special processing - similar to Apple's new iPhone 11 series. Speaking of Apple, not only the matte glass back, the camera arrangement is reminiscent of the design of the new iOS phones from Apple too. There appears to be a lot of copying between brands lately. A selection of new features As we said in the intro, for the first time, Google has installed not one, but two camera sensors in the upper left corner and arranged them in a slightly protruding, rounded square. The similarity is not to be overlooked, even if the iPhone 11 Pro Max counts one extra sensor. A fingerprint sensor that used to be found on the back of the Pixel phones is now missing - Google waives the fingerprint unlock function now, and like Apple since the iPhone X - it's now relying on facial recognition. As Google fans will remember, the Pixel 3 XL had to put up with a lot of criticism with its rather large Notch, so this time around, Google decided to abolish it altogether. The upper edge of the screen is noticeably wider than the lower one, because in addition to the 8-megapixel front camera, a new mini-radar system that uses infrared sensors is located here. The 3D face recognition should be particularly fast and secure but so far there are few tests available. Now with radar?! So how does this work? In the first demo we saw, the Pixel 4 unlocks very quickly - even if you pick it up from the table, it unlocks. Very cool. Basically, the radar recognises the movement of the hand and prepares the sensors for unlocking. We're not quite sure why other phones haven't added this function before as it sounds so simple. In addition, this new fandangled radar allows gesture control from the air, which is especially useful if you can not touch the smartphone i.e. if you have wet or dirty hands. The controller works reliably and should work better than smartphones that do this with a camera-based technology (for example the LG G8s ThinQ). According to Google, this technique called "Motion Sense" is still in its infancy, but we expect loads of apps to utilise this feature over the coming months and years. Pixel 4 in the UK - Pricing, Contract cost The Pixel 4 launch price in the UK is expected to be about £750, but this may change. You can already pre-order the Pixel 4 or the Pixel 4 XL (for slightly more money) on a monthly contract, and your shiny new Pixel phone will arrive on launch day. What's more, for a limited time only, you can also get a Chromebook FREE when you pre-order from Carphone Warehouse, Mobiles.co.uk, EE, Vodafone, ID Mobile on a monthly contract, or if you prefer to buy outright then we are told this deal will also apply there.
