It’s hard to tell exactly how many colours Vivo’s new V25 Pro comes in. At first glance there’s ‘surfing blue’, ‘aquamarine blue’ and ‘sunrise gold’. But expose any of them to bright UV light and their fluorite glass rear panels will subtly change shade. On the front is a 6.56in AMOLED with 120Hz refresh rate; inside is an octa-core MediaTek Dimensity 1300 processor with up to 12GB of RAM and a 4830mAh battery; the triple camera setup on the back comprises a 64MP main snapper with optical image stabilisation, an 8MP ultrawide and a 2MP macro. Oh, and it also comes in black, but that one doesn’t change colour so you’d have to be a total dullard to pick it.
