You're asking all the right questions, and I can see you're trying to balance clarity with control. Here's a breakdown of what’s possible and what’s not:
Why Open Camera Can't Match UHD30 (3840x2160)
Open Camera relies on Android’s Camera2 API and the device’s hardware capabilities. Even if your Samsung phone supports UHD30 (3840x2160 at 30fps), Open Camera may not expose that resolution due to:
- API limitations: It may default to resolutions that are officially supported via Camera2.
- Device-specific constraints: Some Samsung models restrict third-party apps from accessing full camera capabilities.
What you can try:
- Go to Open Camera > Settings > Video Settings > Video Resolution and look for any 4K options like 3840x2160 or UHD.
- Enable Camera2 API:
Settings > Advanced > Use Camera2 API (experimental)
Then restart the app and check if UHD30 appears under video resolutions.
If UHD30 still isn’t available, Open Camera simply doesn’t have access to it on your device.
Lock Screen While Recording in Samsung Camera App?
Unfortunately, the Samsung default Camera app doesn’t offer a built-in “lock screen while recording” feature like Open Camera does. There’s no official way to prevent accidental touches or stop recording unless you:
- Use Pro Video mode and avoid touching the screen.
- Record with the phone placed securely and avoid interaction.
Workaround apps:
- Tasker: You might be able to create a custom automation that disables touch input or overlays a lock during recording, but it’s complex and not guaranteed to work with Samsung’s Camera app.
- Third-party camera apps: Some apps like Filmic Pro offer advanced controls and might include screen lock or gesture-based stop recording, but they may not match Samsung’s image processing quality.
Final Thoughts
If clarity is your top priority, stick with the Samsung Camera app at UHD30. If control and accidental touch prevention matter more, Open Camera with screen lock is a solid choice—though you’ll sacrifice some resolution.
Would you like help exploring Filmic Pro or Tasker setups to mimic screen lock behavior? Or maybe we could sketch out a hybrid workflow that balances both clarity and control.

I have used Open Camera for endless times though, there might be some sort of kill switch to prevent accidental swiping, depending on how much you use display settings, frankly I use the timer of fifteen seconds.
