Using your phone in the cinema without annoying anyone

18 October 2026

Good phone etiquette in the cinema comes down to one rule: use your phone outside the screen, and put it away once the film starts. If you have to look at it inside, keep it brief, silent and as dim as it will go. A lit screen in a dark room pulls every eye in the row behind you.

When it’s fine to use your phone

Outside the auditorium, nobody minds. The foyer, the queue for snacks and the corridor are all fair game. That is the place for messages, tickets and checking the time of the last train.

Inside the screen, the rules tighten as the lights go down. Plenty of people glance at their phone while the adverts play, but some cinemas ask for more than that. Picturehouse’s terms, for example, say your phone must be switched off or on silent before you enter the auditorium, and that you must not use it during the screening. Other chains word it differently, so if you aren’t sure, assume the stricter version.

When it isn’t

Once the film starts, the phone goes away. That means no scrolling, no texting under your coat, and no quick check of the score. People notice all of it.

Filming is a separate matter, and it goes beyond manners. Picturehouse’s terms say it may ask you to leave, with no refund, if you bring a camera or recording equipment, and it asks people not to wear any technology that can record images in the auditorium.

If you really must answer something, a call from a babysitter or a message from work, take it outside. Stand up, go to the corridor and deal with it there. Our guide to whether you can leave the cinema and come back in covers how to do that without fuss.

Why a lit screen bothers the row behind

In a dark auditorium, the film is meant to be the only bright thing in view. A phone screen at normal brightness sits right in the eyeline of the people behind you, and a new light in a dark room is hard to ignore. One person checking a message can pull a whole row’s attention away from the film.

It costs you, too. In Scientific American, an investigator at the US National Eye Institute explains that the eyes take 20 to 30 minutes to adapt fully to the dark, and that the time depends on how bright your surroundings were before. A bright screen in your hand is bright surroundings, as far as your eyes are concerned.

Brightness and sound

If you need to look at your phone in the dark, set it up before the film starts.

Turn the brightness right down. On an iPhone, Apple says you can open Control Center and drag the brightness down. Our guide to dimming your phone screen below its normal minimum goes further, with step-by-step settings for iPhone and Android.
Use a dark theme. Apple’s own support page describes Dark Mode as suited to low-light places. White pages are the worst offenders in a dark room.
Silence everything. Switch the phone to silent and turn off vibration. A buzz on a hard armrest carries further than you think. Check that no alarm is due to go off during the film.
Hold it low. If you must look, keep the phone below the seat back in front of you, and tilt the screen towards you.

Reading on the walk back

There is one time when reading your phone at the cinema makes sense: in the corridor, on the way back from a break. You have been out for a few minutes, the film has moved on, and you want to know what you missed before you sit down.

Do your reading before you go back through the door. Finish the page, lock the phone and put it in your pocket, then go in. If you need a little light to find your row, point the screen at the floor.

An app that asks for nothing in your seat

We built The Bit You Missed around these rules. It asks for nothing while you are in your seat: no camera, no microphone, and no lit screen. You don’t start anything before the film, and your phone stays in your pocket until you step out.

On the way back, you open the web app, pick your film, drag a dial to roughly how far in you are, and let go. You get short lines, one per scene, such as “A sick Triceratops stops the tour and Ellie stays with it.” The screen is dark with dim amber text, and there is no light mode to switch into. Read it in the corridor, put the phone away, and go back in. Our guide to catching up on a part of a film you missed covers the other options.
