Hey Everyone,

The Public Test Channel (PTC) for Quest v78 started to roll out today for Meta Quest 2, Meta Quest Pro, Meta Quest 3 and Meta Quest 3S.

If you're seeing an issue or bug after updating to PTC v78:

1) For issues: Go to our Get Help board and search for any existing thread on the issue, if you don't find one, make a new thread. Please add the tag "PTC v78" to the thread and in the title. This way everyone can look for just PTC v78 issues too.

2) For bugs: If you come across a bug, please post each one you spot in its own thread, to keep track of individual issues separately. Please make sure to also send in bug reports along with posting on the forums if you notice anything going wrong.

Share your impressions in the comments below and let us know if you see any issues.

We know it's tough when you run into a problem on a PTC build and want to thank you all again for testing out PTC and sharing your feedback! This feedback is extremely helpful to our engineering teams. We appreciate your interest and persistence in testing out the core functionality of software as we develop!

    The 1028 version has restored backend control, which is great, but the issue of remote desktop unavailability in V78 has not been fixed yet

    LTCuddles119 Have you updated? Someone said that the recently released v78.1028 has already fixed this issue

    quantum0300 Please read the first 4 words of my post. Not to be rude but it is the first thing I say.

    It appears a few people have been remedied of the issue, but it's as random as the people that weren't effected at all by the bug in the first place.

    LTCuddles119 Sorry, I didn't notice. Maybe you can try shutting down and restarting? As far as I know, when Quest 3 is turned off, pressing the power button and volume button, selecting power off from the menu, and restarting can solve some problems. I hope this can help you

    quantum0300 As stated before, please read my post. Maybe in it's entirety.

     Hello, I'm providing feedback on some persistent bugs I'm experiencing on my Quest 3, currently on system version v78.
    Here is a summary of the issues:
    * IPD Display Glitch: After some time in use, the IPD (Inter-pupillary Distance) display incorrectly shows "min" as the value, even when the physical slider has not been moved from my calibrated position. This seems to be a software display bug.
    * Audio Popping/Cracking: I'm experiencing occasional, loud audio pops. This is not a hardware speaker issue, as the problem persists when using headphones. The popping is most frequent and noticeable when I use Virtual Desktop and switch from my PC desktop view back into a VR scene. This issue has been present for the last several system versions.
    * Battery Pack Charging/Compatibility Failure: I use multiple head-strap battery packs that I hot-swap during long sessions. Previously, this worked perfectly. Now, on v78, when one battery pack dies and I connect a fully charged one, the headset fails to start charging 100% of the time.
    * Evidence: I can confirm via the OVR Metrics Tool that no power is being drawn from the new battery.
    * Workaround: To fix this, I have to first connect the official wired charger for a moment, unplug it, and only then will the headset recognize and begin charging from the newly attached battery pack.
    I hope the engineering team can look into these issues, as they impact the user experience significantly. Happy to provide more data or logs if needed. Thanks!

    Still no list about what changed.
    Still no META feedback on users comments
    Still no handle on the new navigator to bring the screen closer for hand interaction
    Still not a friendly setup for hand interaction
    Is there somebody at Meta that knows anything about community engagement ?

    I've been having the same problems since upgrading to v77. When the headset is turned off, the connected BOBOVR battery stops charging. The LED still indicates charging, but the power drops to 0.5 watts (measured). What's strange is that the headset's battery level decreases instead of increasing after 1 hour. Is it possible that my headset is charging the BOBOVR battery? Very strange. I tested with two different batteries --> same behavior.

    sadly, no!

    As part of the upgrade to V78 1028 I've got the move with me window setting in the task/settings bar thingy underneath the main windows. Surprisingly for meta, it works.

    Now I've just got to find the two things they borked to compensate for this.
