If your Android camera won't open, the usual cause is that another app is holding
the camera, a permission or privacy toggle is off, or the camera app's cache has
gone bad. Start by opening the camera in a second app, such as WhatsApp. If it
works there, the fault is in one app and clearing that app's cache or data
usually fixes it. If the camera fails in every app, restart the phone, then boot
into Safe Mode. A camera that still fails in Safe Mode points to the system
camera service or the hardware. Below is a two-minute diagnosis and 12 fixes,
easiest first.

This post covers the camera **failing to start**. If the camera opens and then
crashes or freezes partway through, that's a different problem, and it has its own
guide: [camera app keeps crashing on Android](/blog/camera-app-keeps-crashing-android).

## Quick diagnosis: what exactly are you seeing?

Name the symptom before you touch any settings. Each one points somewhere different.

| Symptom | Most likely cause | Start with |
|---|---|---|
| App opens, viewfinder is **black**, no error | Privacy camera toggle off, another app holding the camera, or a frozen camera service | Fixes 1, 2, 3 |
| **"Camera failed"** / **"Can't connect to camera"** | Camera service blocked or crashed, corrupted app data, sometimes hardware | Fixes 3, 5, 6, 8 |
| App **never launches** or closes instantly | Bad app update, full storage, mismatched GCam port | Fixes 5, 7, 8, 11 |
| Works in some apps, not others | Permission or data problem in that one app | Fixes 4, 5 |
| Fails everywhere, even in Safe Mode | System or hardware fault | Fixes 8, 12, then repair |

## The isolation test (do this first)

Open the camera in at least three places: the system Camera app, a messaging
app's camera (WhatsApp or Telegram), and Instagram or any third-party camera.

- **Fails in only one app:** the problem lives in that app's permissions, cache
  or data. Fixes 4 and 5 usually solve it.
- **Fails in every app:** the shared Android camera service, the firmware or the
  camera module is at fault. Work through fixes 1–3 and 6–8, then the hardware
  checks.

## Fix 1: Close anything else using the camera

Only one app can hold a camera at a time. Video-call apps (Zoom, Meet,
Teams), flashlight widgets, screen recorders, QR or document scanners and some
"magnifier" apps can keep hold of it in the background. That leaves your camera
app with a black screen or a "Can't connect to camera" error.

On Android 12 and later, look for the **green dot** in the top-right corner of
the screen. If it's there while your camera app is closed, something else is
using the camera. Pull down the notification shade and tap the indicator to see
which app it is, then force stop that app. Turning the flashlight off also helps,
because on many phones the flash LED goes through the same camera service.

## Fix 2: Turn on Camera access in Quick Settings (Android 12+)

Android 12 added a **Camera access** privacy toggle. When it's off, apps don't
get an error. They get a blank black preview, which looks exactly like a broken
camera. Swipe down twice, find the **Camera access** tile (you may need to edit
the tiles to see it) and turn it on. On some phones the same switch is under
**Settings > Security & privacy > Privacy**.

## Fix 3: Force stop the camera app and restart the phone

A frozen camera service tends to stay frozen until something restarts it.

1. Go to **Settings > Apps > Camera** and tap **Force stop**.
2. Restart the phone.
3. If that doesn't work, power the phone **fully off**, wait 30 seconds, then
   turn it back on. A full power-off resets the camera hardware more completely
   than a quick restart does.

## Fix 4: Check the app's camera permission

Go to **Settings > Apps > [the app] > Permissions > Camera** and set it to
**Allow only while using the app**. If you once tapped "Don't allow", Android may
never ask you again, and the app will simply show black or close. Check the
**Microphone** permission too, since some apps refuse to start video without it.

## Fix 5: Clear cache, then clear storage

In **Settings > Apps > Camera > Storage**:

1. Tap **Clear cache**, then open the camera again.
2. If it still fails, tap **Clear storage** (also called Clear data).

Clearing storage resets the camera's settings (resolution, grid, saved modes,
watermark options) to factory defaults. It doesn't delete your photos, which are
stored in the gallery and not in the app's data. Do the same for whichever
third-party app failed in the isolation test.

## Fix 6: Boot into Safe Mode

Safe Mode starts Android with every third-party app disabled. Samsung recommends it for "Camera failed", and it works the same way on most phones.

- Samsung and most other phones: hold the power button, then long-press
  **Power off** on the screen until **Safe mode** appears, and tap it.
- On some phones, hold **Volume down** while the phone boots.

Open the built-in camera while in Safe Mode. If it works there, a third-party
app is interfering. Likely culprits are recently installed apps, cleaners,
"battery boosters", screen dimmers and other camera apps. Restart normally and
uninstall them one at a time, testing after each. If the camera still fails in
Safe Mode, skip ahead to updates and the hardware checks.

## Fix 7: Free up storage

A phone that's nearly full can stop the camera app from starting at all, or let
it open and then fail when it tries to save. Check **Settings > Storage** and aim for at least 1–2 GB free, more if you record video. Old videos and the Downloads folder are usually the quickest wins.

## Fix 8: Update or roll back the camera app and Android

- **Settings > System > Software update** (Samsung: **Software update >
  Download and install**). Camera faults are often fixed in firmware patches.
- Update the Camera app itself from the Play Store or Galaxy Store if it's
  listed there.
- If the trouble started right after an update, open **Settings > Apps >
  Camera**, tap the three-dot menu and choose **Uninstall updates** where the
  option exists. That puts back the factory version of the app.

## Fix 9: Reset camera settings (Samsung)

When a Galaxy shows **"Warning: Camera failed"** but the app does open briefly,
open the Camera, tap the **gear icon** and scroll to **Reset settings**. If the
app won't open long enough to get there, use Fix 5 (clear storage), which does
the same job from outside the app. Then try Safe Mode (Fix 6). If "Camera failed"
still appears in Safe Mode on a Galaxy, it's usually firmware or hardware. You can run a camera test yourself in the
**Samsung Members** app under **Support > Phone diagnostics** before contacting Samsung service.

## Fix 10: Check the flashlight as a hardware clue

Turn on the flashlight from Quick Settings. If it's greyed out or says the
camera is in use while nothing else is running, the camera service or the module
may be at fault. It proves nothing by itself. Combined with the signs further down, though, it helps you decide whether to keep trying software fixes.

## Fix 11: Custom ROMs and GCam ports

Installed a GCam port or flashed a custom ROM? Then a mismatch is the first suspect. A GCam build made for another chipset or Android version may not
open at all. It can also crash on launch, or show black on one lens. On custom
ROMs, the camera can stop working completely if the vendor camera files don't
match your firmware. The fix there is to reflash the correct vendor or firmware
package for your model.

For GCam, try a build made for your exact phone model and Android version, or
remove it and use a Play Store camera app instead. We cover this in detail in
[GCam port not working? Fixes and alternatives](/blog/gcam-port-not-working-alternative)
and compare the approaches in [GCam vs an AI camera app](/blog/gcam-vs-ai-camera-app).

## Fix 12: Factory reset (last software step)

If the camera fails in every app, in Safe Mode, and after updates, a factory
reset is the last software step worth trying. It rules out corrupted system
data. **Back up first** (Google One, Samsung Cloud or a computer), because the
reset erases everything. Then go to **Settings > System > Reset options > Erase
all data**. Test the camera *before* you restore your apps. If it fails on a
clean phone, the cause is hardware.

## Signs it's hardware and needs a repair shop

No app or setting will fix these:

- The camera fails in every app, in Safe Mode and after a factory reset.
- It started after a drop, a cracked back, or water exposure.
- The camera module clicks, buzzes or rattles when you open the app (often
  a damaged stabilizer or focus motor).
- The flashlight also fails, or only one lens works while the others show
  black.
- You see visible fog, cracks or dust inside the lens.

An authorized service centre or a reputable repair shop can test the module and its ribbon cable.

## When a different camera app makes sense

If the camera works in Safe Mode or in other apps, and only your stock app
keeps failing, or you'd simply like a different camera, installing another one
from the Play Store is a reasonable workaround. **Open Camera** is free and
lightweight if you want manual sliders.

**SensePose** is our free camera app for Android 8.0+. It enhances every photo
on the phone as you take it: better colour and tone, cleaner low light, and AI
face enhance on supported phones. The first 5 enhanced photos are free; after
that, photos still save free at full resolution, and one small payment unlocks
enhanced photos forever. To be clear about the limits: SensePose uses the same Android
camera service as every other app. If that service or the camera hardware is
broken, no app (ours included) can open the camera. Fix the underlying fault first; a new app won't paper over it.

## FAQ

### Why won't my camera open on my Android?

The most common causes are another app holding the camera, a denied camera
permission, the Android 12+ Camera access toggle being off, or corrupted camera
app data. Test the camera in a second app to see whether one app or the whole
system is affected. If it fails everywhere, restart the phone and try Safe Mode.

### Why is my camera just a black screen on Android?

A black preview with no error usually means the Camera access privacy toggle in
Quick Settings is off, or another app such as a video call or flashlight is using
the camera. Turn the toggle on, close background apps, force stop the camera and
restart. If it's black in every app even in Safe Mode, the camera module may be
faulty.

### Why does my Android phone keep saying "Camera failed"?

"Camera failed" means the app couldn't connect to the camera service. That
usually comes from corrupted app data, a conflicting app, or a firmware bug. Clear the
camera app's cache and then its storage, install system updates, and test in
Safe Mode. If the error appears in Safe Mode and after a factory reset, it's a
hardware problem.

### My Samsung phone says "Camera failed". How can I fix this?

Restart the phone, then clear the Camera app's storage under Settings > Apps >
Camera > Storage. You can also use Reset settings from the camera's gear menu.
Boot into Safe Mode by long-pressing Power off. If the camera works there,
uninstall recently added apps. If it doesn't, run Phone diagnostics in Samsung
Members and contact Samsung service.

### Why is my phone not letting me access the camera?

Android blocks access when the app's camera permission is denied or the
system-wide Camera access toggle is off. Check Settings > Apps > [app] >
Permissions > Camera and set it to "Allow only while using the app". Work
profiles and parental controls can also block the camera.
