Real-world test Huawei's new imaging hardware has caused as much excitement in the smartphone market as anything since Nokia's oversampling champ of 2013, the Lumia 1020. Benchmarker DxOMark puts both the Huawei P20 and P20 Pro comfortably ahead of all rivals, including the Galaxy S9 Plus, Pixel 2 and iPhone X.

Huawei will be very happy to hear comparisons to Nokia's 41MP triumph, particularly as head of imaging Eero Salmelin was Nokia's imaging chief when the Lumia 1020 was launched – we spoke to him here in a technical overview of the 1020. There are some similarities too – the new P20 also packs in an unfeasibly large oversampling (40MP) sensor, can do lossless optical zoom, and also captures audio strikingly well, another Nokia trick. But after using the new Huawei phones extensively over the long weekend, I made an interesting discovery.
