12 Smartphone Gadgets for 2019.

An unusual tiny printer you swipe across paper, though tall images were hard to get right.

A case that turns your screen into a glasses-free 3D display, unlike any accessory he has tested.

Unlike most cheap knockoff lenses, this 120x lens with built-in LEDs surprised him.

A comfortable phone VR headset with built-in buttons and a surprisingly good range of content.

Accurate AR tracking and some interesting surprises, but no blockbuster games.

Not exciting, but practical for keeping wound cables tidy.

Clip-together cable modules that stop cables tangling, and one he likes.

Warm, decent-looking gloves that double as a fingerprint-polishing cloth, which surprised him.

A customisable phone grip that does the job but is not the best he has used.

A unique way to revive an old watch with wireless payments, though not a design winner.

A textured mouse mat with a built-in Qi charger that needs no precise placement.

Earthquake putty that holds a phone up well and is what he uses for hidden-phone shots.

Waterproof payment ring he prefers to the watch strap, though he is not a ring person.
