I would like to uninstall the default camera app and instead use the FOSS Open Camera. And I would also like to access the camera from the lockscreen.

How can I do this in Android 6?

  • Thank you but I don't have my phone rooted. If I need to keep the standard camera that's fine too as long as I can change the default camera app.

  • Default camera is a system app, which requires root to uninstall default camera app. You can use Titanium Backup like app to remove system app (N.B: Removing system app will be harmful to your device).

  • Settings->Security, under device security, tap on settings icon near screen lock. Select Lock screen shortcuts. Tap on any left or right default icons, prompts to choose action: tap on select application. Tap on Apps on top, and select your required camera app(These setting is on Lineage 14.1 android nougat)


While uninstalling the pre-installed camera app can be difficult as others have mentioned, it should be relatively easy to change your default camera app to Open Camera (or whatever camera app you prefer). I prefer Open Camera as well, so I also wanted the same thing.

To make Open Camera the default (or any camera app other than the pre-installed version), follow these steps:

  1. Download camera app of choice (in your case, Open Camera)
  2. Wait until it installs.
  3. Turn off screen with power button (don't turn off phone, just screen), turn screen back on but stay on lockscreen (don't unlock phone).
  4. Select camera from lock screen (Image 1 below).
  5. Unlock phone if it requests for you to do so.
  6. A pop-up should appear. Choose your desired camera app in the list.
    • IF you have the ability in this menu, select "Always." (Image 2)
    • IF you do not have the ability to select "Always" for the preferred camera app, still select desired app, let app open, go back to lockscreen. Repeat process, the second time you can choose "Always" for your preferred camera app. (Images 3 and 4)
  7. Your phone should launch your preferred app now by default.

Caveats: sometimes when either camera app updates, you have to do the process again. Usually it doesn't happen too often, only when big changes occur to the apps. Hope that helps!

    For those who already set the stock camera as the lock screen camera default, how do you clear the lock screen camera default so that you can set the default again? (no way to disable system camera app on asus zenfone 4 max zc554kl)

Android keeps changing how you can remove an app that's been set as the default for an action. Currently my phone is using Android 11; here, you need to go to:

  1. Preferences
  2. Apps and notifications
  3. See all apps
  4. Camera
  5. Advanced
  6. Open by default
  7. Clear defaults

There are also some apps that will show you the default app for all the various categories and skip you to this spot in preferences directly, which I find more convenient so I don't have to remember this long navigation tree.

Once you've done this, you can open the camera app via your normal shortcut (eg pressing power button twice on my phone) and you'll get the dialog that asks which app you'd like to use for that action in the future.
