OnePlus 6 Midnight Black

Mentioned only as last year's OnePlus phone that the 7 Pro greatly improves on.

If you can get it for less, it may be a better buy than the 6T, with the same chip and performance in a slimmer, lighter body.

Part of the generation where night photography improved markedly, with the fingerprint scanner moved to the back.

Mentioned as an example of a phone using basic 2D face unlock, which is the least secure biometric.

Compared with the LG G7; OnePlus succeeded through how it pitched the phone, not through better hardware.

Used as a reference point: the 6T keeps its dual camera set-up, and has a smaller battery and faster fingerprint scanner.

Mentioned in a question as already one of the fastest phones on the planet, with no review of his own.

Mentioned as a phone that would be well ahead of the A9 for gaming.

Good battery life, finishing third and lasting half an hour longer than the iPhone X.

Best stabilisation, 4K 60fps and the most detailed selfies, but its overly bright images hurt low-light photos and cost more.

Mentioned as a performance comparison, with the Poco F1 offering even more bang for the buck.

Included as a battery comparison, with no verdict available.

Mentioned as the baseline for the 6T: it has a glass back, introduced OIS and has a faster in-display scanner than the Vivo Nex.

Fantastic value for money if you don't need to wait for the 6T's expected camera improvements.

His number one for value: $500 couldn't be better spent, with fast chip and clean software, only the camera is a minor compromise.

Excellent HDR and dynamic range with the sharpest low-light video, though a blue tint crept into low-light video after an update.

Used as a benchmark: its dual camera and snappiness are only just ahead of the Mi A2.

A bold, vibrant red version of the OnePlus 6 that keeps the same price and is still good value, though colour choice is down to taste.

Second fastest and quicker than the S9+, but there is a delay between scanning and the display turning on.

A cheaper phone with a better camera and a faster fingerprint scanner than the NEX, and one of the best displays at its price.

Falls behind the S9 Plus in night photos and brightens the image to compensate, though its video is respectable.

Fastest Android phone of the moment with a good camera and display at a low price, with only small sacrifices such as no wireless charging or IP rating.

Wins on dynamic range, noise, detail and portrait mode, and costs half the price of the iPhone X, though its video colours are overdone and it lacks optical zoom.

Slicker, slimmer and faster-feeling than the S9 Plus and much cheaper, though it lacks IP certification and has less storage.

Expected to be a big new flagship with top specs that undercuts rivals by about $200, though likely pricier than before.
