Before anything else, there is a test that costs two seconds and settles most of this question. It comes from one sentence in Apple’s own documentation.
One line from Apple’s documentation, and it is the whole diagnosis. Put a finger on the dot
and drag. If it moves, it is a control that iOS is drawing — a setting, switched on, doing
exactly what it is designed to do. If it stays exactly where it is while everything else moves
under it, it is not this. That single test takes two seconds and separates a settings question
from a hardware one.“To move the AssistiveTouch menu button, drag it to a new location on the
screen.”
Assuming it moved, there are two things Apple documents that put dots on an iPhone screen. They look different from each other, and telling them apart takes no tools.
Apple: “Turn on AssistiveTouch. The AssistiveTouch menu button appears on the
screen.” Tapping it opens a menu of up to eight icons. It can look faint rather than solid, because Apple provides Idle Opacity — a setting
to “adjust the visibility of the menu button when not in use”. Apple: “animated dots on the edges of the screen that represent how the vehicle is
moving”. And the detail that identifies it: on Automatic, the dots “appear on the screen when
iPhone detects that you’re riding in a car… the dots are hidden when the motion
stops”.AssistiveTouch
one dot · draggable · opens a menu
Vehicle Motion Cues
several dots · at the edges · only in a car
The distinction is easy once it is named. One dot that you can drag and tap is a control. Several dots at the edges that drift while the car moves are a display. The first opens a menu; the second does not respond to touch at all, because it is not there to be touched.
The AssistiveTouch one is worth understanding rather than just switching off, because it explains why it appeared. Apple describes what the button is for: reaching Control Center, notifications, the Lock Screen or the App Switcher, performing gestures, and — the important part — being used “when you need to press iPhone buttons”. It is a substitute for hardware buttons, built for people who cannot use them comfortably.
Which raises the obvious question of how it got switched on. Apple answers that too, in a tip.
This is how a dot arrives without anyone deciding to add one. A triple-click of the side
button is not a deliberate gesture — it is something a hand does in a pocket, or a child
does, or you do while trying to do something else. The shortcut exists so that people who need
AssistiveTouch can reach it instantly; the same speed is what puts it on the screen of somebody
who has never heard of it. Nothing is broken and nothing was installed.“To quickly turn AssistiveTouch on or off, you can set up the Accessibility Shortcut,
then triple-click the side or Home button.”
Siri is the other route Apple names — “Ask Siri something like, ‘Turn on AssistiveTouch’” — which is worth knowing for the same reason: a phrase said near a phone can produce a dot that nobody chose from a menu.
Two different places in Accessibility, and neither is where people look first.Turning each one off
The Vehicle Motion Cues case has a cleaner tell than any setting screen, and it is worth using before opening anything. If the dots only exist while the car is moving and vanish when it stops, that is the Automatic setting doing precisely what Apple describes. Nothing needs diagnosing; the feature is reporting motion, which is its whole purpose — Apple says the dots “may help reduce motion sickness” for a passenger.
Apple attaches a safety note to that one, and it belongs here rather than in a footnote: Vehicle Motion Cues “should not be used while operating a moving vehicle and in other situations requiring attention to safety”, and they “work best when you’re seated facing forward in the vehicle”.
Who answers this question. Of the results a search engine returned for it on the day this floor was written, six of the first seven were published by companies that sell iPhone repair or “system fix” software. That is a count of who publishes, not a judgement of what they wrote — this floor has not audited those pages. It is worth knowing only because of what sits at the other end of the question: the two explanations documented by Apple are both settings, and both are switched off in the same app, for nothing. A page whose business is selling repair software is answering the question from a different direction than a page that is not.
What this page cannot tell you is what a dot that does not move and does not match either description is. Apple’s accessibility documentation covers the two features above; it does not describe screen faults, and neither will this floor. If the test at the top failed — the dot stayed put under your finger — then the question has left the settings app, and the honest next step is Apple Support rather than a page written by somebody who cannot see your screen.
The floors below take it three ways: the test and what it separates, the settings themselves, and the neighbouring things that appear on an iPhone screen without being asked for.
Three ways in, and the first is the two-second test.
Drag it. A control moves because iOS is drawing it; anything that stays put under your finger is a different kind of question, and not one a page can answer.
AssistiveTouch and Vehicle Motion Cues, both in Accessibility, both free, and both switchable in a few taps. One arrives by triple-click; the other by getting into a car.
Indicators, dots and letters that appear without being asked for. Each is reporting something, and each has its own documentation.
It will not suggest repair software. The two explanations Apple documents are both settings, switched off in the Settings app, at no cost.
It will not diagnose a dot that does not move. Apple’s accessibility documentation describes two features, not screen faults, and this page has no way to see your screen.
And it will not treat AssistiveTouch as a nuisance. It is a substitute for hardware buttons built for people who need one, and it is on your screen because a shortcut is easy to trigger. What holds instead is simple: the instruction that the AssistiveTouch menu button is moved by dragging it, the description of what AssistiveTouch does and the note that the menu button appears when it is turned on, the Idle Opacity setting, the Accessibility Shortcut triple-click tip and the Siri phrase, the location of both settings in Accessibility, and the description of Vehicle Motion Cues as animated dots on the edges of the screen with the Automatic behaviour, the Control Center route and the safety notes are quoted from Apple’s iPhone User Guide, listed below.
