It lights the room courtesy of the f/1.78 aperture but the colours are artificial (the Windows screen is more blue – see below), and detail is lost. Still a good social media shot.

Pass – the camera is strong shows a balanced sensor/lens setup. The Selfie at 32MP has all the usual beauty features.

GadgetGuy’s take – the vivo S1 is a strong mass-market device with an excellent BBK pedigree.

There is a lot to like and little to complain about this phone. Solid, well-made and offering features (particularly the battery and selfie camera) that make it excellent value.

Funtouch 9 is a little different at first and reflects its home market.

In the beginning, I said it was a crowded category. Would I spend $50 more and get the OPPO Reno Z, Moto One Vision or Samsung Galaxy A50?

The answer is in two parts – if $449 is your budget you are buying the best value phone. It scores 5-out-of-5 for that price.

 If you have $50 more, the OPPO Reno Z is very enticing with NFC and a 48MP rear camera. Then it scores 4.7-out-of-5.
