The OnePlus 3T is the next phone from OnePlus and a sequel to the OnePlus 3 which the firm described as a "flagship killer".
Below is round-up of the key information on the new handset. Keep your eyes peeled for updates and our review.
The OnePlus 3T builds on the specs of its predecessor. We assume that the 'T' stands for Turbo, because the new handset offers an incremental upgrade in the shape of the Qualcomm Snapdragon 821 chipset.
That's the same chipset used in Google's Pixel and Pixel XL, two phones that the OnePlus 3 beats in benchmarks today. The generous 6GB of RAM remains in place.
In addition to the 64GB model, the OnePlus 3T also offers a new 128GB storage option, as well as a new gunmetal colour.
The other big talking point is the camera hardware. On the rear you'll find a 16MP Sony IMX398 sensor that incorporates phase-detection autofocus, f/2.0 aperture and improved Electronic Image Stabilisation system. There's a 16MP camera on the front, compared with the 8MP sensor on the previous model.
You'll find an identical 5.5in Full HD AMOLED display, support for USB Type-C and OnePlus' Dash technology that the firm claims will get you a full day's charge in just 30 minutes. Speaking of which the battery's been given a boost - replacing the 3,000mAh of old to 3,400mAh.
The OnePlus 3T runs Android 6.0 rather than the newer Android 7.0 Nougat, but OnePlus' custom OxygenOS hasn't gone anywhere. However there's been some tweaks, this time around it benefits from a cleaner and more streamlined UI, resized app icons, customisable quick access icons, and password or fingerprint protection for individual apps.
Price and release date
The OnePlus 3T will be available direct for £399, making it around £70 more expensive than the OnePlus 3 before it.
O2 is also offering the OnePlus 3T on a paid monthly basis. The 64GB model is available to order for £9.99 on a £31 tariff with 500 minutes, unlimited texts and 500MB of data, which can be upped to £42 per month for a more reasonable 5GB of data.
The 128GB OnePlus 3T is available for free on a choice of £33 or £44 per month tariffs.
