Check Android front camera field of view
Check how much of a scene your Android selfie camera shows, compare its framing at a fixed distance, and learn why other apps may crop the view.
Your selfie camera may show less of the room in a video call than it does in the camera app. Or you may want to know whether the front camera can fit two people in the frame before a meeting or recording.
Use the Camera Test to view the Android front camera in your browser. You can compare what fits in the picture, but a browser preview cannot provide a calibrated lens measurement, and other apps may crop or zoom the image differently.
Check the front camera view
- Open the Camera Test on your Android phone. When the browser asks to use the camera, allow access.
- Set the phone on a steady surface or hold it at the distance where you normally take a selfie. Keep the camera lens at the same height and angle you plan to use.
- Look at the preview and note which objects appear at the left and right edges. Use fixed objects, such as a doorway or the edges of a bookshelf, so you can compare the framing later.
- Move the phone farther away or closer, keeping it pointed in the same direction. Notice how the visible area changes. A wider view includes more of the scene at the same distance.
- Compare the browser preview with your camera app or video-call app from the same position. Keep the phone distance and angle consistent, and check whether the app has zoom, portrait effects, or framing options enabled.
The Camera Test shows a live preview and reports camera resolution and frame rate. It does not have a calibrated field-of-view measurement, so use the preview to compare framing rather than treating it as a precise angle reading.
What the result means
The preview includes more of the room than the other app
The camera itself may be fine. The other app could be cropping the image to fit its video shape, applying digital zoom, or using a different camera mode. Look for a zoom or framing control in that app, and compare again with effects turned off.
The preview looks tight at arm’s length
A close phone position naturally makes your face take up more of the frame and leaves less room for the background. Move the phone farther away, if practical, or use a wider front-camera setting if your phone and app offer one. Some phones have more than one front-camera view, but the browser may not expose every camera mode.
The image looks mirrored
Mirroring changes left and right, not how much of the scene the lens sees. Some selfie previews reverse the picture like a mirror, while saved photos or meeting apps may display it differently. Judge the edges and amount of visible scene, not the direction of text or objects.
The preview is black or the browser cannot open the camera
The browser may not have permission, another app may be using the camera, or the phone may not be offering a front-camera stream to that browser. Check the permission and app fixes below before assuming the camera is broken.
How to fix a view that seems wrong
- Allow camera access for the site. In Chrome on Android, tap the site controls beside the address bar and allow camera access for TooLab, then reload the page. You can also check Chrome › Settings › Site settings › Camera. The exact labels can differ between Android versions and browsers.
- Check Android camera permission. Open Settings › Apps › Chrome › Permissions › Camera and allow camera use while the app is in use. If you use another browser, open that browser's app settings instead. Also check the phone's privacy controls to make sure camera access is not disabled for all apps.
- Close other camera apps. Exit video calls, camera apps, and apps that add face effects, then reload the test. Android may prevent the browser from opening the camera while another app is using it.
- Check distance and phone position. Put the phone at eye level and hold it still. Compare views from the same spot, since even a small change in distance can noticeably change how much of the scene fits.
- Turn off app effects and zoom. In the video-call or camera app, disable digital zoom, portrait framing, and automatic follow features for a comparison. These controls change the delivered picture even though the lens has not changed.
- Restart the browser and phone. If the preview stays black after permissions are allowed and other camera apps are closed, restart the browser. Restart the phone if the camera remains unavailable across apps.
If you compare the browser test on a computer as well, Windows 11 camera access is under Settings › Privacy & security › Camera. On a Mac, check System Settings › Privacy & Security › Camera and allow the browser. These settings affect whether the browser can open a camera, not its field of view.
Why the same camera can look different in each app
Field of view means how much of the scene the camera captures from a particular position. A browser preview is displayed inside a page, and the page may fit the video into a shape that does not match the camera image exactly. Video apps can also crop the image to fill a widescreen or portrait frame, or apply digital zoom and face tracking.
For a rough comparison, place two markers a known distance apart across the scene at the phone's position, then check whether both appear near the preview edges. This only estimates framing in that setup. It does not reveal the camera's exact lens angle, and moving the phone or changing the video shape changes the result.
The Camera Test asks for camera permission before showing the preview. Close the page when you are done, especially on a shared phone.
