EDITORIAL: Oppo's OnePlus skipped 14 to bring us an iterative upgrade of excellent OnePlus 13. The 15 is a very competent and affordable flagship with excellent build and performance, amazing endurance and fast charging, good screen and reliable camera setup. It adds AF selfie and replaces the excellent 3-step alert slider with an AI button. Also gone is the Hasselblad collaboration and branding, in fact: all cameras have been downgraded. Is it possible that Oppo reserves top performance for it's Find series? Find 9 Pro and OnePlus 15 share very similar design...
