You tap the camera button, the preview stays black, or people in the room ask why you’ve gone quiet. On an iPhone, this is almost never broken hardware. It’s a permission, and iOS hides it in two separate places. This guide is phone-first. If you’re on a laptop or desktop, our guides to a microphone not working in your browser and a webcam showing a black screen cover that ground already.
Why the camera won’t work on iPhone: two locks, not one
On a computer, the browser alone decides who gets the webcam. On an iPhone, there are two locks. The first sits in the iOS Settings app and controls what Safari may do in general. The second sits inside Safari and controls whether one particular website may use your camera and mic.
Both have to be open. If the general setting says Deny, the website never even gets to ask, so tapping the camera button does nothing at all. And if you once tapped Don’t Allow on a pop-up in a hurry, Safari remembers that answer for that site. Either way it looks like a fault, when it’s really just a saved choice.
How to allow camera and microphone in Safari on iPhone: 4 screens
It takes about two minutes. Go through all four, even the ones you think are fine. The one you skip is usually the culprit.
Screen 1: Settings, Safari, Camera
Open Settings. On a recent iOS, Safari lives under Settings → Apps → Safari. On older versions, it’s straight under Settings → Safari. Scroll down to the section called Settings for Websites and tap Camera. Pick Ask or Allow. Avoid Deny: that’s the one that blocks everything without a word.
Screen 2: same place, Microphone
Go back one level and tap Microphone, right below. Same options, same advice: Ask or Allow. Lots of people fix the camera and forget the mic, then wonder why the room can see them but can’t hear them.
Screen 3: the website’s own request
Head back to the site and switch on your camera or mic. Safari shows a pop-up along the lines of “[site name] would like to access the camera”. Tap Allow. Read it before you tap, because a refusal here sticks for that site.
Screen 4: per-site settings behind the “AA” button
Said no by accident? Don’t go digging through iOS Settings: the fix is inside Safari. Tap the “AA” icon on the left of the address bar (on some versions it’s a small page menu button in the same spot), then Website Settings. You’ll find Camera and Microphone for this site only. Switch them to Allow or Ask, then reload the page.
Allow saves you from answering on every visit. Keep it for sites you know and trust, and leave Ask for everything else.
Special case: Private Browsing asks every single time
In a Private Browsing tab, Safari forgets your choices once the tab is closed. Come back to the site and the question pops up again. That’s not a bug. Forgetting everything is the whole point of private mode.
If the repeated prompt drives you mad, open the site in a normal tab and set Camera and Microphone to Allow through “AA”. If you’d rather stay private, just get used to tapping Allow at the start of each session. And check screens 1 and 2 first: if those say Deny, even a private tab can’t ask.
Screen goes dark, Low Power Mode: the camera cuts out
iOS shuts off Safari’s camera and mic as soon as the page leaves the foreground. Lock the screen, swipe home, or hop into another app to read a text, and your video stops. That’s a privacy safeguard, not a glitch. When you come back, you’ll often need to restart the camera from inside the chat.
The sneaky one is Low Power Mode. When it’s on, the battery icon turns yellow and Auto-Lock drops to 30 seconds. You’re listening to a conversation without touching the screen, it goes dark, and your camera goes with it. A few ways round it:
- plug the phone in and turn off Low Power Mode in Settings → Battery;
- with it off, lengthen the delay in Settings → Display & Brightness → Auto-Lock;
- failing that, give the screen a tap now and then to keep it awake.
Incoming calls and other tabs: who stole your mic?
An iPhone hands the microphone to one thing at a time. A phone call, a FaceTime, a WhatsApp voice note or a Voice Memos recording all jump the queue ahead of Safari. During the call, your mic in the chat goes silent. After you hang up, it doesn’t always come back by itself, so toggle the mic off and on in the room, or reload the page.
Tabs compete too. If another Safari tab is already using the camera or mic, say a video meeting or another site, whichever starts last takes over and the other goes quiet. Close tabs you don’t need. There’s a handy clue at the top of the screen: a green dot means the camera is live, an orange dot means the mic alone.
The quietest thief of all is Bluetooth. Connected AirPods become the default mic. If you’re talking into the phone while your earbuds sit in your pocket or in an open case, nobody hears a thing. Disconnect them, or put them in.
Safari vs Chrome on iPhone: same engine underneath
On an iPhone, Chrome, Firefox and Edge all run on the same engine as Safari, because Apple requires it. The paintwork differs; the engine doesn’t. So switching browsers rarely fixes a camera problem. If a page won’t use your camera in Safari, it probably won’t in Chrome either.
The two-lock logic stays the same; only the address of the first lock moves. For Chrome, the switch is in Settings → Apps → Chrome (or Settings → Chrome on older versions), with separate lines for Camera and Microphone. After that, the website asks for itself inside Chrome, just like in Safari. If you said no the very first time iOS asked on Chrome’s behalf, that Settings page is where you go to undo it.
On iPad: same settings, a few extra traps
An iPad follows the exact same four screens. A few situations are iPad-only, or at least more common there:
- Multitasking. In Split View, Slide Over or with several windows open, the camera may pause while Safari shares the screen. Make Safari full screen.
- Where the camera is. On recent iPads, the front camera sits on the long edge. Held upright, you’ll look off to one side, so turn the tablet landscape and make sure your hand or the case isn’t covering the lens.
- The family iPad. A Screen Time restriction can turn the camera off for every app. Look in Settings → Screen Time → Content & Privacy Restrictions → Allowed Apps, on the Camera line.
That last restriction exists on iPhone as well. If the Camera app has vanished from the Home Screen, it’s nearly always the reason.
When nothing works: restart Safari, then the phone
Checked all four screens and still staring at black? Work through this list from lightest to heaviest:
- Close the tab, don’t just go back. Going back keeps the page in memory, stale state and all. Tap the tabs button, close the site’s tab with its cross, then open it again.
- Quit Safari. Swipe up from the bottom of the screen, pause, then flick the Safari card upwards.
- Try the Camera app. If the camera doesn’t work there either, the problem isn’t Safari or the website.
- Restart the iPhone. It frees a mic or camera that another app is still holding on to.
- Update iOS if a new version is waiting in Settings → General → Software Update.
Once it works: camera and mic in the chat
LibertiChat runs straight in Safari: free, no sign-up, nothing to download, just pick a nickname. In a voice room, you ask for the floor, then talk once it’s your turn. For your webcam, you choose who can watch from six visibility settings, from everyone down to restricted, where you approve each request one by one. The chat help page walks you through those buttons step by step.

Frequently asked questions
Why does Safari keep asking for my microphone on every visit?
Either the site is set to Ask, or you’re in Private Browsing. In a normal tab, tap “AA”, then Website Settings, and set Microphone to Allow for that site.
Safari isn’t listed under Privacy & Security → Camera. Is that normal?
Yes. Safari is Apple’s own app, so its camera and mic access live under Settings → Apps → Safari, in Settings for Websites. Third-party browsers such as Chrome do show up in the Privacy list.
People can see me but can’t hear me. What now?
Check that Microphone is allowed on both screens, not just Camera. Disconnect any forgotten Bluetooth earbuds, and in a voice room, remember to ask for the floor before you speak.
