Review OnePlus has settled into the groove of releasing two flagships a year, and this Christmas-time 5T reiteration may well piss off the fans who bought the OnePlus 5 released in the summer. It's better all round, sports the 6-inch 18:9 OLED that's a genuine flagship display... and it's the same price as before. So £499 buys you some absurd specs: 8GB of RAM and 128GB of storage, and £449 6GB/64GB.

We found that the release software of the OnePlus 5 let it down, with cellular network radio performance and imaging a bit wobbly on my review unit, but I found the 5T a more mature package all round. For technically confident buyers the hardware on offer can’t really be beat at this price, if you're comparing RAM and storage.
