- Recording starts but stops after a second

Likely causes

- CommonSoftware glitch or app conflictA temporary bug can block the video recording function specifically.
- CommonOverheating limiting video recordingVideo recording generates more heat than photos and can be restricted when the phone is warm.
- PossiblePermission or settings restriction (e.g., microphone access denied)Some phones require both camera and microphone permission for video to start.
What to do
- Free up storage space by deleting unused files.
- Check that both camera and microphone permissions are granted to the camera app.
- Let the phone cool down if it's been in heavy use or direct sun.
- Restart the phone and try again.
- Try recording at a lower resolution or frame rate.
- Update the operating system and camera app.
