The Samsung Galaxy S10 arrived in March 2019 as the phone that set the template for every Samsung flagship since: a hole-punch Dynamic AMOLED screen, an ultrawide camera alongside the main and telephoto lenses, and an ultrasonic fingerprint reader under the glass. Seven years on it is very much a used and refurbished buy, and it holds up better than most phones of its age. The 6.1-inch panel is still one of the nicest small-flagship displays you can get, the aluminium and glass build feels expensive, and the triple camera covers 0.5x to 2x without you having to think about it. The compromises are the ones you would expect from a 2019 phone. The 3,400mAh battery was never generous and will be weaker still on a used handset, the Exynos 9820 runs warm, and Samsung's software support ended with Android 12 and One UI 4.1, so there are no further security patches. What you do still get is a headphone jack, microSD expansion, IP68 protection and Wireless PowerShare, features Samsung has since dropped or scaled back. It suits someone who wants flagship hardware and a compact-ish body without paying flagship money.
