A tiny screen that finally fixes rear-camera vlogging — as long as you never press its shutter button

I record most of my videos on the back camera, because it's the good one. The problem is obvious the second you try it: you can't see yourself. You line the phone up, walk into frame, guess, and hope. I've cut my own head off doing this.

So I bought a mini vlog screen — a little white square that snaps onto the back of the phone and shows you what the rear camera is seeing. It's about the size of a matchbox. On the iPhone, it works exactly as advertised, and there's one thing on it that flatly doesn't work at all.

It snaps on and stays on

First surprise: the finish. This is a polished, smooth shell, not the slightly rough plastic these no-name gadgets usually come in. It's very light, and it holds nicely in the hand.

On the back it's MagSafe, so on an iPhone it just snaps into place and sits flat. My Galaxy S26 doesn't have MagSafe built in, so there you either use a MagSafe case — which is what I did — or stick the metal ring from the box onto the phone.

On the side of the unit you get an ON/OFF slider with an indicator light, a brightness button, and a shutter button. Remember that shutter button.

What's actually in the box

A short USB-C to USB-C cable, a USB-C to Lightning adapter for older iPhones, the stick-on metal ring, the Bluetooth remote with a coin cell inside, and a manual.

The cable is the one thing worth flagging: it's very short. That's fine if the screen is on the back of the phone, but if you want to hang the screen somewhere else, you can just use your own longer USB-C cable instead. Nothing is proprietary.

I couldn't test the Lightning adapter — my iPhone is USB-C — but it's there in the box if you're on an older one.

The app is an Android thing — iPhone doesn't need it

The leaflet points you at a QR code, so I scanned it. The page took a while to load, and then it showed me Google Play, Huawei, Honor, Xiaomi, Vivo, and a direct download.

No App Store. I spent a moment confused, and then realised that's the point: on iPhone you don't install anything. The companion app is only for Android.

On iPhone, you just plug it in

That turned out to be true. I connected the cable to the iPhone and the screen was already showing my camera — no permission prompt, no pairing, no app.

It's not a touchscreen, and there's no auto-rotation, so you align the picture yourself. But the payoff is immediate: I could see myself, see where the frame ended, and fix my position before recording instead of after. That's the whole reason to buy this thing, and it does it.

Brightness surprised me too. At full brightness I could read it clearly under studio lights, which is where most small screens like this fall apart. It also has no battery — it only powers on when it's plugged into the phone — so there's nothing to charge and nothing to run flat.

The shutter button doesn't take pictures

Here's the part I didn't expect. I pressed the shutter button on the unit, and nothing happened. No photo.

I unplugged and replugged in case iOS wanted to ask me for a permission. It didn't ask for anything, and it still didn't take a picture. Then I paired the Bluetooth remote — it shows up as a "BShutter" device in iOS Bluetooth, default pairing password 1234 — and tried the remote instead. Also nothing for photos. I tried it with video too. Then I read the printed documentation properly, and I still couldn't make it fire.

On Android you're running an app

I moved over to the Galaxy S26, unpaired the remote from the iPhone, and installed HCLink. That link is slow, so it's worth knowing the app name before you start.

Once it's installed, mirroring works. But every time you plug the screen in, Android asks what you want to share — just the camera app, or the entire screen. Whole-screen mirroring is genuinely useful for some things, but it does mean this isn't plug-and-play the way it is on iPhone: you're picking the mode each session.

And the camera button still didn't work here either, which is the part that annoys me most — on Android the app is talking to the device directly, so that's exactly where you'd expect it to work.

What I didn't test

I used this for one session. I haven't lived with it, so I can't tell you how the shell or the magnets hold up over months. I couldn't test the Lightning adapter, I didn't test a wireless variant of this product (this is the wired one, deliberately — fewer things to go wrong), and I didn't measure the screen's resolution or colour accuracy in any real way.

Verdict

The screen itself is good, and the screen itself is the product. On an iPhone it is genuinely plug-and-play: snap, plug, see yourself. The build is nicer than the no-name branding suggests, it's light, it needs no charging, and the brightness holds up under real lights. It comes in other colours too, orange included.

The shutter is a miss. Neither the button on the unit nor the bundled remote took a photo for me, on either phone, after re-plugging, re-pairing and reading the manual. If that's why you're buying it, don't.

I still like it, and I'll keep using it — because I do film on the back camera, and I have genuinely ruined shots by misjudging where I was standing. This fixes that. I just start the recording the normal way.
