(Pocket-lint) - Google's Pixel 3 and Pixel 3 XL smartphones are the latest premium smartphones to join the flagship Android party. The two devices are the poster boys for Android's software, offering pure, vanilla Android Pie and all the best features Google has to offer.

The Samsung Galaxy S9 and S9+ are six months older than the Pixel devices but they are excellent handsets, offering Android with Samsung's UX Experience over the top, packaged in a beautiful design. Here is how Google's Pixel 3 and 3 XL compare to Samsung's Galaxy S9 and S9+.

Google Pixel vs Samsung Galaxy design

  • Galaxy S9: 147.7 x 68.7 x 8.5mm, 163g
  • Galaxy S9+: 158.1 x 73.8 x 8.5mm, 189g
  • Pixel 3: 145.6 x 68.2 x 7.9mm, 148g
  • Pixel 3 XL: 158 x 76.7 x 7.9mm, 184g

The Samsung Galaxy S9 and S9+ feature beautiful, premium designs. They have a solid metal frame sandwiched between two glass panels, both of which curve at the edges. On the front of both handsets is Samsung's Infinity Display with a small bezel at the top and the bottom, while on the rear you'll find a fingerprint sensor and Samsung branding. 

The S9+ has a dual camera system on the back, while the standard S9 has a single lens system. Both have USB Type-C at the bottom with stereo speakers either side and neither have a 3.5mm headphone jack. The S9 and S9+ are both IP68 water and dust resistant and they come in three colour options, comprising Lilac Purple, Midnight Black and Coral Blue.

The Google Pixel 3 and 3 XL go down the premium design route too, both offering metal frames with a glass back that is divided into two different textures. The top quarter of the rear on both handsets is glossy, featuring the single camera lens, while the bottom three quarters is matte with the subtle "G" branding at the bottom and a circular fingerprint sensor in the middle.

Unlike the Samsung devices that look the same from the front and different from the rear, the Pixel 3 and Pixel 3 XL look different from the front and the same from the rear. The Pixel 3 has larger bezels at the top and bottom of its display with built-in front-facing speakers, while the Pixel 3 XL opts for a notched display at the top, featuring a speaker in the bezel beneath the display. Both have squeezable sides for launching Google Assistant. 

The Pixel devices are waterproof like the Samsung devices and they also have USB Type-C and no 3.5mm headphone jack. Three colours are available including Not Pink, Clearly White and Just Black.

Google Pixel vs Samsung Galaxy price

The Samsung Galaxy S9 is currently available from £679 on Samsung's website, while the Samsung Galaxy S9+ is available from £799 on Samsung's website.

The Google Pixel 3 will start at £739, with pre-orders open now on Google's device store. The Pixel 3 XL will start from £869 and it too is available to pre-order from Google's device store.

Google Pixel vs Samsung Galaxy conclusion

The Google Pixel 3 and 3 XL and the Samsung Galaxy S9 and S9+ are pretty much like-for-like in terms of specs. The Infinity Display on the Samsung devices is arguably more enticing than certainly the smaller Pixel 3 and possibly the Pixel 3 XL too, depending on how you feel about notched displays.

You get a bit of extra RAM on the S9+ too, as well as a dual rear camera and you also get microSD on the Samsung devices. You get a pure Android software experience on the Pixel devices though, along with everything Google Assistant has to offer and a dual front camera.

Ultimately the decision on which to buy between the Google Pixels and the Samsung Galaxy S devices comes down to your preference for design, software experience and price. The S9 is £60 cheaper than the Pixel 3 currently, while the S9+ is £70 cheaper than the Pixel 3 XL so that's worth bearing in mind but we will update this feature when we have reviewed the Pixels in full.
