Screen went dark when testing a Unity build

Hi there,

I'm testing a build of my Unity project on the Quest 3 (installed through the MQDH), and after a few minutes, the HMD just went dark (while the headset is on my head and with me actively testing my app) with what I believe is the "sleep mode" sound effect (the "shooooo" sound like you are moving away). If I press the Meta button on my right controller, the screen lights back up, and I can resume.

I tested running the Horizon World to rule out the proximity sensor's problem, and I stayed in a world for 30 minutes without the screen going dark.

I believe it might be some specific settings in my Unity project. Is it possible to log what's making my HMD go to sleep (that's what I'm assuming when the screen goes dark) and monitor it through ADB?

    After updating to V85, I encountered the same issue. Whenever I run any non-system app, the screen suddenly goes black and the device enters hibernation mode within a minute, requiring me to press the power button to wake it up. This completely disrupts my normal usage😅

      Ok, thanks for the info. I just downloaded the Battle Talent demo from the store and played for 15 minutes without the screen going black.

      BTW my Meta XR SDK packages in Unity remained v78.0.0, but I believe my MQDH, Link and Quest OS are up to date (not sure if MQDH and Link version matter though because I'm running standalone). Just checked my Quest 3 system version is v83.1034

      I also want to add that the HMD also turns black even when I'm testing the project in Unity via the Link, but I didn't have this issue before.
