Biometric issues

The Samsung Galaxy S8 looked space age when it was launched last year, and the Galaxy S9 apes it in many ways. It's not the top phone in Samsung's range any more, but it's jolly close and it seems that retailers are starting to discount it both SIM free and on contract, which is why it's jumped up our list.

Screen: The screen was the very, very best on the market and is still now a top performer, coming with the elongated, 18.5:9 ratio that stretches impressively up and down the phone - very similar to that on the current Galaxy S9. With powerful colour reproduction and contrast ratio that make everything look clear and crisp, it’s also got the QHD resolution that we expect from all the top phones.

Battery life: The battery life, despite being smaller than in previous devices from Samsung, is still pretty decent. It's not amazing, but it's not very far from the performance of the Galaxy S9 and will last around a day... although you might want a little top up, which can be achieved quickly through a wireless charger or the speedy adapter in the box.

Camera: The camera is still very strong, despite being usurped by the S9 - the auto mode offers clean, crisp and clear shots every time and combined with screen quality makes you want to show off your best snaps. There’s an easy-to-use pro mode as well to get the best out of your snapping.

Mini verdict: This is the phone to go for if you want a strong performer and don't mind it's a little older. As such, it's much cheaper than it was at launch and thus offers fantastic value for money.
