Banners over whatever is on the screen

The phone interrupts itself constantly and you have arranged your life around it doing that. The interruptions are drawn on top of everything, including whatever you were reading and whatever you were capturing.

The habit

You leave notifications on because a phone with them switched off stops being a phone.

Why it is automatic

This one was not learned from any single app. It was the deal from the beginning: carry the device and it will tell you things. People arrange their attention around that promise and stop checking manually. Switching it off feels like breaking the device rather than configuring it.

The design reinforces it in small ways. A banner is transient, so ignoring it costs nothing. It is drawn over the app rather than replacing it, so nothing is interrupted for real. It is readable in the corner of an eye.

There is also a social component. People expect replies at a speed that only works if the phone is announcing things, so turning that off has a cost measured in other people being annoyed.

What it actually does here

A banner is drawn by the system, over the top of the frontmost app. The app underneath is not told and cannot prevent it. Whatever page is open at that moment is the background of somebody else's message for a few seconds.

Captures include it. A screenshot records the composited screen, so if a banner is visible when you press the buttons, the banner is in the file with the sender name and the first line of the message. Screen recordings are worse, because they run for long enough that arrival is likely rather than unlucky. That file then follows every rule described on taking a screenshot to remember it.

Lock screen previews are readable without unlocking, on the settings most phones ship with. Anyone who picks the phone up off a table, or sits opposite it while it lies face up, reads the first line. That is not surveillance. It is the phone doing what it was set to do, in a room that happens to contain other people, which is the whole subject of the room the screen is in.

The timing belongs to the sender. You cannot pick the moment a message about something unrelated appears over a page you would rather not have on screen with a name attached to it. The one thing you can pick is whether the phone is in a state where anything is allowed to appear at all.

What a banner does to a recording

People record their screens to show somebody a problem or to keep a copy of something that only exists on screen. A recording is a much longer exposure than a capture. It runs for as long as the demonstration takes, during which the phone carries on being a phone.

Anything arriving in that window is in the file. Not only banners: a call, a battery warning naming the device, the top of a message thread if you pull the tray down without thinking. Sharing a recording is a larger act than sharing a capture, and it is worth watching one back first.

The lock screen as a surface other people read

A phone on a table is a small always on display. It lights up by itself, shows the first line of things, and does it at eye height for anybody sitting across from it. Most owners have never seen their own lock screen from that angle, because they are always the person holding it.

Two settings usually cover this. One hides message contents until the phone is unlocked. One stops the screen waking when something arrives. Neither costs you the notification, only the preview.

What to do instead

The goal is to control the moment rather than to give up notifications, because giving up notifications is not a thing most people can actually sustain.

1. Before you start reading anything you would rather not have a banner over, put the phone into the mode that silences interruptions, and turn it off again when you finish.
2. Set lock screen previews to hide contents until unlocked, which keeps the alert and removes the readable line.
3. Turn previews off for the specific apps whose messages you would not want read aloud by whoever picks the phone up.
4. Take any capture with interruptions already suppressed, so the file cannot contain a banner in the first place.
5. Watch a screen recording back before it goes anywhere, at full length, rather than trusting your memory of what was on screen.

How to notice you did it anyway

This one leaves evidence in your own files, which makes it one of the easier habits on this site to audit after the fact.

• Look through your recent captures for a strip of banner across the top. It is usually the first thing you stop seeing.
• Put the phone face up on a table and send yourself something, then read the lock screen from where another person would sit.
• Open the notification settings and read which apps are allowed to show previews rather than assuming you remember.
• If your phone keeps a notification history, open it and see how much of the last hour would have been readable.
• Check whether anything you shared recently included a banner, and whether the person you sent it to is somebody who should have seen that name.
