If you're in the UK or Europe the OnePlus Nord 2T is the best mid-range phone you can buy for under £400/€400. Great battery life, super fast charging, a 90Hz OLED screen, and quick performance make it superb value for money - but only two Android software updates isn't good enough.
Excellent performance; Great main 50Mp camera; Super-fast 80W charging;
Only two Android version updates; Pointless mono camera; Other phones have 120Hz at this price;
