Smartphone Gadgets you might not believe Existed...

Sceptical at first, but cheap, easy to set up and satisfying to use in games like PUBG.

The best screen magnifier he has used, with great packaging and little distortion when tilted.

A bit of a novelty, but handy for typing on the go and decent to type on.

A tiny, cheap projector with compromises, but one of the best cheap ways to expand a phone screen.

Sealed to ten metres and adds a Bluetooth remote shutter for underwater photos.

Not a fan of phone lenses generally, but this four-in-one is the one he would take.

A compact metal gadget that slowly pans a phone on a tripod for cinematic time-lapses.

A slick, low-profile three-spot wireless charger with two extra USB ports.

Good value way to get NFC automation, especially for people with lots of smart gadgets.

Cool to see but not something he'd recommend, and electromagnets are bad for phones.
