Re: It’s for the Rolex wearers.
I'm tempted by an iPhone 8, but may wait until models with rear-facing 3D sensors appear to take advantage of the SoC's features, rumoured to on the next gen of iPhones. Qualcomm are pushing active IR 3D scanning for the Android set too, so if an OEM puts in a phone with a very good camera I'll get it.
Til then, very tempted by OnePlus 5T, shame the camera is only average and there's no waterproofing - but these concessions take a couple of hundred quid off the sticker!
