"SystemUX keeps stopping" when trying to open Camera app.

Honored Guest

Hey there. My girlfriend and I just bought fresh Quest 2s and she's suddenly run into an issue with casting to devices. 


Whenever we try to cast using her phone, it says it's connected, then gets stuck in a loading loop where the only option is to hit "stop casting." During this time, the quest itself has the red casting light in the top right, and seems to still be casting even after we close the connection on the phone.

We tried to cast from within the quest itself by going to the camera app, but every time we do, the app closes instantly. Occasionally, we'll open it up and the app will open correctly, but only for a split second. Then it throws a "SystemUX Keeps Stopping" error. From here I can either close the app or go to app info. Both options end up closing the app and only about 5% of the time does "app info" actually bring me to the app info. We've tried force stopping the app and it did nothing.

This issue seemed to start after we got her air link working, so I tried to reopen air link. Doing that is what finally got the app info to work a few times. 


We've tried disconnecting both the phone and the quest from the internet, connecting both to a different network, turning wifi off on both, soft and hard restarting both, and even restarting the router. Nothing has worked.

The phone app is having a hard time connecting to the quest 2 as well. It says the quest 2 isn't connected to wifi, but it definitely is. We can use the store and stream videos and all that.

We've done everything short of a factory reset. Any additional recommendations before we do that would be helpful. Thanks!

Hey there, @DaffyDesert. Thank you for reaching out and bringing your casting issues to our attention. We know that any sort of issue that has to do with app connections and casting can be inconvenient at best, and we would like to lend a hand to help out.


Are all 3 devices on the exact same network? (Ex., if the router has a 5GHZ and 2GHZ channel, all the devices must be on the same channel.)


There are a few things you can try to improve the quality of the casting:

  • Lower the graphics settings in the app, if possible.
  • Try to limit any interference between your Casting device, your router, and the Quest Headset.
  • If your router supports it, try connecting to the internet via 5Ghz connection rather than 2.4Ghz.

If you're still having issues with this and haven't done a factory default, here are the steps to do so: First, please do a cloud backup to save your data.


To perform a factory reset using your phone:


Open the Meta Quest app on your phone.

Tap Devices in the bottom menu.

Tap the headset connected to your phone.

Tap Advanced Settings.

Tap Factory Reset and then Reset.


To perform a factory reset using the headset:


Turn off your headset.

Hold the power and volume (-) button on your headset down simultaneously until the boot screen loads on your headset.

Use the volume buttons on your headset to highlight Factory Reset and press the power button.

Use the volume buttons on your headset to highlight Yes and press the power button.


Please let us know how this goes. We are looking forward to your reply.
