"If you’re hunting for the best Android camera phone at this price, and one that doesn’t skimp on specs the OnePlus 9 is worth considering. Courtesy of a partnership with Hasselblad, the cameras offer better color correction, and both regular and ultra-wide photos look great. The OnePlus 9’s battery fully charges in under 30 minutes over a cable, and in 45 minutes using wireless charging. If you hate waiting for hours to charge your phone, you'll love the OnePlus 9."

"Despite not boasting the same camera credentials as its pricier sibling, the Samsung Galaxy S23 Plus will remain a top-tier handset for several years thanks to its industry-leading processor and magnificent display. It may prove an attractive proposition for Galaxy newcomers in the market for a big-screen all-rounder."
