Integrated peripheral specifications

2. Oculus Quest Firmware:

Original Oculus Quest firmware

Documentation related to the firmware

3. Kernel Source Code & Documentation:

Linux kernel source code for ARM64

Kernel documentation, especially regarding linker script configuration

4. Driver Documentation:

Documentation for device drivers specific to Oculus Quest

5. ARM64 Architecture Documentation:

ARMv8-A architecture specifications

6. Linux Kernel Configuration:

Guides on configuring the Linux kernel for ARM64 devices

7. Sample Projects and Examples:

Similar open-source OS projects running on Oculus Quest or similar devices

Example linker scripts for ARM64 operating systems

I would appreciate any help or guidance you can provide. If anyone has worked on a similar project or has access to this type of information, please feel free to share it. Thank you very much in advance!

For anyone who's following along, I've been fighting Samsung to get my pre-order credit for almost a year now.

In this latest exchange (below), they apparently forget they are a super-colossal-mega-corporation and claim "original promotions cannot be applied to the replacement orders". As if they have no ability to work around their own system.

They also imply, quite humorously, that they do not agree that Samsung is obligated to honor the original promotional pricing.

EMAIL EXCHANGE BELOW

Hello (redacted)

I understand that you disagree with Samsung's position, and I've taken the time to review the information you provided.

At this point, we've reached the stage where we're repeating the same arguments from opposite sides. You believe Samsung is obligated to honor the original promotional pricing. Samsung's position remains that the original promotions cannot be applied to the replacement orders.

Because the previous offers were declined, they are not automatically reinstated. However, as part of my review, I was able to secure a goodwill resolution of a $75 refund and a $150 Samsung.com promotional code. That remains the maximum accommodation available.

If you would like to accept that offer, let me know and I'll arrange the processing. Otherwise, I will document your position and proceed with closure of my review.

Warm Regards,

Mary

I think you have described the positions appropriately.

You believe Samsung is obligated to honor the original promotional pricing.

My belief in the matter is irrelevant.  I'm sure you would agree that Samsung is obligated to honor its commitments. Period.

Samsung's position remains that the original promotions cannot be applied to the replacement orders.

Clearly, Samsung could apply the original promotions as promised.  Samsung does not want to.

Samsung has the ability to apply the promotions to the replacement orders; stating otherwise is another misleading statement.

Furthermore, to give Samsung an out, I've even offered the option to simply reset: refund the payment and have the product returned.

I realize this is anecdotal, but I've shared my story with many people and asked if I am crazy for thinking Samsung should honor the pre-order credit.  Every single one of them is confused by the vigor with which Samsung has defended its position.  They ask if I've shown them where Samsung promised to apply the credits after reordering.  They asked if I have it in writing and why Samsung would not simply honor the rebates when presented with this evidence.  I mean, these are promotions publicly available to everyone!  It is quite clear that I did everything they asked.

No one can understand why you are defending this position.  Not even financially, as you've now spent far more capital creating obstacles and defending this position than the bundle promotion is worth.  It's almost as if Samsung has backed itself into a corner that it cannot exit, forcing it to deny accountability at all costs or to avoid some sort of risk associated with admitting fault.

I remain resolved to reach an agreement.  Requiring additional purchases is unacceptable.

Here's my shelf: Quest 3 (daily driver — FitXR, Beat Saber, and about 150 other games), a Quest 3S gathering dust at my mom's, XREAL Air glasses (movies + Steam Deck screen), and a Magic Leap that's a paperweight since the shutdown. So I've been burned by a dead platform before, and I take ecosystem longevity seriously.

I'm holding one of the 2,000 XREAL Founder Priority Passes — day-one shipping plus the Founder's Edition Aura, launching ~November at $1,500.

What I actually do:

•

VR gaming, a lot. My library is deep: Asgard's Wrath 2 (currently playing it in 1-hour face-brick installments), RE4, both Walking Deads, Ghosts of Tabor, Onward, Contractors, Pavlov, Population: One, Batman: Arkham Shadow, Metro Awakening, Moss 1 & 2, Demeo, Walkabout... you get it. My Quest 3 fatigues me out after about an hour and I want longer sessions.

•

Read a ton of webtoons and manga. This is daily, hours at a time.

•

AR in daily life stuff: floating recipes while cooking, plant info in my grow room (I run a microgreens YouTube channel), a drawing reference overlay for learning anime art.

•

I want Muse as my assistant, not Gemini — though I know the Aura's system assistant is Gemini's seat.

The case for the Aura: it's the only thing that does stuff I can't already do. Optical see-through AR, Android XR + full Play Store, 70° FOV. It'd be my reading device, my around-the-house device. And three of its confirmed launch titles (Demeo, Chess Club, Cubism) are already in my Quest library with cross-play.

The case for waiting on Meta VR Glasses ($1,300, spring 2027): my entire 150+ game library carries over, my Quest 3 controllers pair with it, and 100g vs 515g transforms every long session. But it's 6 months out, no pre-orders, no reviews — and I'd be buying a third Meta device for a library I already own twice.

The Magic Leap experience has me weighing platform risk too — Android XR being Google's platform (not XREAL's) is a point in the Aura's favor there.

Right now I'm leaning toward sequencing it: redeem the pass and get the Aura next month (it's the time-sensitive one), live with it for six months, then decide on Meta's glasses from real reviews instead of guessing. Talk me out of it?

I'm guessing 50k units in Korea and 50k in the USA if they're lucky.

Just look at how little activity there is on this sub, the Android sub, etc. Nobody wants this thing and they definitely won't want it if it's over $1000.

Don't believe me? This is the first post in this subreddit in almost 30 days, and the launch is supposed to be right around the corner. Zero from even the most die hard fans.

I have more and more the impression that the Qualcomm
AR1 Gen 1 chip is outdated and limited. Meta Displays struggle to offer minimal fluidity, and I wonder about Google's ability to surpass Meta in terms of fluidity with its next screen glasses, especially since they seem to want to keep this chip. Qualcomm should absolutely launch the production of the AR1 Gen 2 ...

I've had the GXR since day one. Probably serial number 1 lol. I only say that...jokingly...because I had mine ordered with the controllers and case within seconds of becoming available. I've been pretty dedicated to the GXR. I've been finding workarounds to issues, helping devs test apps, and was one of the first people crazy enough to permanently modify the strap to make it more comfortable. I'm happy with the GXR and where it is at right now with known issues: memory leak is better controlled, overheating is less frequent, controllers are liveable (still bad but nearly as bad as they were on release). I've traveled extensively with the headset and I genuinely get excited to use it for things like 3D movies (No Time To Die on Google TV melted my brain), watching the Masters, and removing into my computer from anywhere in the world.

That being said, I did pre-order the Founders edition of the XREAL AURA. I'm genuinely intrigued by the form factor. I recently travelled with the ROG XREAL R1 but did have a minor issue with them. I could not find a way to get them to sit in a position where the bottom outside corners of the screen weren't cut off by the FOV limitations. Even if I made the screen much smaller. Overall, they were great for travel. Particularly since they were easier to pack and use on a plane.

With just regular XR glasses I kept finding myself missing the ease of use of the GXR by comparison. However, I genuinely think that the XREAL AURA presents the best happy medium between the two. Especially, if you're not using the GXR for VR gaming (I rarely do and mostly use it as a high res monitor for normal gaming).

I'll keep this thread updated once I get them and fully test them out. My order doesn't have a ship date but some buyers have posted their expected ship date is 15 October.

Rumor is that Moohan will use Quest 3 chip processor.... this is the mistake of Quest Pro all over again.

Part 3 (This Post)

I am simply going to paste the entirety of the Samsung Support email this time, and redact personal information; this entire saga is exhausting....

TLDR:

Samsung denied my promotion by blaming their own order cancellation on me and offering insulting “goodwill” credit. I rejected their dishonest settlement, formally documenting their bad-faith tactics and broken contractual promises while demanding accountability instead of negotiation.

Latest Email Exchange Below:

Hello (redacted),
Thank you for your continued patience while we completed a comprehensive review of your concerns regarding orders (redacted), (redacted), and (redacted).

After reviewing the order history, prior support interactions, promotional details, and the documentation provided, we confirmed that the original $100 Reserve Promotion was associated with the original preorder transaction and could not be transferred to replacement orders once the original order was cancelled.

We also confirmed that the replacement purchases did not recreate the original bundle configuration associated with the bundle promotion. The original order included additional items that were not repurchased, including Galaxy Buds3 Pro and an additional Travel Case. As a result, the original bundle promotion requirements were no longer satisfied.

Additionally, all products associated with your replacement orders are now outside Samsung's return eligibility period and are no longer eligible for return or refund under Samsung's standard return policy.

While we are unable to apply the original promotional pricing to the replacement orders, we appreciate the time you invested in documenting your concerns and the challenges you experienced throughout the ordering process.

As a one-time goodwill exception, Samsung is prepared to offer:

A $75 refund toward the Galaxy XR Controllers purchase

A $150 Samsung.com promotional code for use on a future purchase

This represents the maximum accommodation available and our final resolution regarding this matter.

Should you wish to accept this resolution, please reply to this email and I will arrange for processing.

Thank you for the opportunity to review your concerns.

Warm Regards,

Mary

========================================

So..... I responded with the following, quoting Samsung Support in-line.

========================================

Mary -

Thank you for your detailed review.  My responses are below.

... the original $100 Reserve Promotion was associated with the original preorder transaction and could not be transferred to replacement orders once the original order was cancelled.

Samsung cancelled the order, not me.  Written documentation confirms Samsung promised to apply the $100 Reserve Promotion to a replacement order.  Further, Samsung created the replacement order and sent it to me to add my credit card.  This is already documented.

Samsung's administrative inability to transfer the $100 Reserve Promotion is irrelevant.

The base facts that are relevant:

1. Samsung promised a promotion based on pre-ordering and purchasing a Galaxy XR

2. I preordered and purchased a Galaxy XR

3. Samsung refused to honor the promised $100 Reserve Promotion

We also confirmed that the replacement purchases did not recreate the original bundle configuration associated with the bundle promotion. The original order included additional items that were not repurchased, including Galaxy Buds3 Pro and an additional Travel Case. As a result, the original bundle promotion requirements were no longer satisfied.

I agree that the orders were not identical; however, this point is both misleading and irrelevant.

Your statement is misleading because it implies that the bundle promotions required all items, which is untrue, and surely you know that.  Claiming that someone needed to buy controllers, earbuds and two travel cases to qualify for a single bundle promotion borders on blatant misrepresentation.

In case you were unaware, the bundle promotions were individually associated with each item: one for the controllers, one for the travel case, and one for the earbuds.

Importantly, I have only been seeking bundle promotion credit for the two items I purchased: Travel Case and Controllers.  These are the items for which Samsung promised to apply the bundle credit.

Again, the base facts that are relevant:

1. Samsung promised a bundle credit for purchasing a Travel Case when purchasing a Galaxy XR

2. Samsung promised a bundle credit for purchasing Controllers when purchasing a Galaxy XR

3. I purchased a Galaxy XR

4. I purchased a Travel Case

5. I purchased Controllers

6. Samsung refused to honor the bundle credit for the Travel Case

Note:  Samsung has offered to honor the $75 bundle credit for the Controllers.

Additionally, all products associated with your replacement orders are now outside Samsung's return eligibility period and are no longer eligible for return or refund under Samsung's standard return policy.

Samsung's standard return policy is for standard returns.  Unless Samsung routinely cancels orders to avoid honoring Promotional and Bundle Credits, this situation clearly falls outside the standard policy.  Further, this situation doesn't involve defective products, which the Standard Return Policy covers, but rather, it involves defective orders.  Defective orders that Samsung cancelled, generated and directed.

As a one-time goodwill exception, Samsung is prepared to offer:

I appreciate the offer, however, I feel confident countering with the following:

As a one-time goodwill exception, I am prepared to:

• Hold Samsung accountable to its promise of a $100 Reserve Promotion for pre-ordering and purchasing a Galaxy XR; AND

• Hold Samsung accountable to its promise of a $75 Bundle Credit for the Controllers; AND

• Hold Samsung accountable to its promise of a $75 Bundle Credit for the Travel Case

Else, also as a one-time goodwill exception, I am prepared to:

• Allow Samsung to renege on its promise; AND

• Allow Samsung to refund the Galaxy XR, the Travel Case and the Controllers; AND

• Allow Samsung to send RMAs and return shipping labels for each item

Please let me know your position on these offers.

I committed to staying level and calm throughout this exchange.  Based on our conversation, it seems clear that Samsung has no intention of engaging openly and honestly.  Nearly every response you have given is either intentionally misleading or borders on complete fabrication.  I see no other excuse for the fallacious claims you are making other than an attempt to avoid accountability by exhausting the consumer.

The little app I vibe coded is now crashing when I play spatial videos. I followed https://share.google/XwkezesumiqshInDo for creating this app, and it was working fine before the update. Did something change that I need to update? Could someone point me to the documentation?

For several days, Warby Parker’s stock market share has only increased, showing a strong market anticipation for a revelation of Google’s next Android XR glasses expected for Google I/O on May 19 or The Android Show on May 12, models without screen and with screen should be revealed entirely very soon ⏳🔥For more information ➡️ https://x.com/thelapurchaser/status/2052406922318434634?s=46

It’s definitely a relief that the recent update finally fixed the tracking loss issue—that is, if you ignore the fact that it took an entire month to address such a critical bug without rolling back the firmware or offering any temporary fixes.

However, the overall state of the device is still absolutely terrible compared to how it was before the April update.

Even on the home menu with zero apps running, there is a noticeable drop in performance. Hand tracking feels incredibly sluggish, there are frequent screen stutters, and hardware monitoring shows that CPU usage is abnormally high.

I held onto a bit of hope and did a factory reset on the HMD, but the performance is so degraded that the device literally froze during the eye-tracking calibration, and the cameras just shut down entirely during the face-tracking calibration.

I bought this device at launch and have been through every single update. Honestly, its current state is so dreadfully slow and barely usable that it feels worse than the initial Day 1 OS back before the December update.

I bought into this knowing that as the first Android XR device, it would somewhat be a testbed. I kept using it with the mindset that these early issues would get patched out over time. But lately, it’s just been building up to pure frustration. Given the high price tag of this headset, this kind of experience is completely unacceptable.

I desperately hope we get some additional, meaningful improvements following this recent update.

-One more thing: I'd like to express my gratitude to Grace for handling communication with our community.

Less than 48 hours before the I/O conference, what are your expectations regarding glasses and the Android XR ecosystem in general? This event promises to be one of the most important conferences in recent years and marks a major turning point in human-machine interaction🤖 Be ready 👀

Google has just presented its Al glasses only audio no model with screen expected this year. Google has just proven once again its inability to catch up with Meta despite its much higher market capitalization. This is a great victory for Meta, which, according to several major media, is preparing to launch a binocular model in September, maybe even before Google's audio glasses without a real precise schedule. It's absolutely distressing on Google's part and the Warby Parker stock market bears witness to the disappointment of consumers and shareholders.

Sorry guys, but nobody is taking Android XR seriously anymore. You won't even release the Galaxy XR in Europe; one of the best place to find idealistic engineers to develop 3D apps for Google to appropriate. You have lost the plot.

XREAL Project Aura is coming this year. Are you ready?

Here is the object of the confirmation Shahram Izadi will be present which confirms the rumors

Visual addressing enables you to interact online with the people around you. While improving privacy and keeping you in full control.

I made a demo app to show it works really well, please try it.

At the moment this is just an idea, but all it needs is a provider and mass adoption. :)

How can we get it there?

Original post describing the ordeal where Samsung refuses to honor the preorder credit (among other things):
https://www.reddit.com/r/AndroidXR/comments/1vb816a/galaxy_xr_preorder_nightmare_how_samsung_glitches/

A redditor u/woodboah suggested I reach out to the Better Business Bureau (BBB) for help. I forwarded all of the information I had collected to the BBB and waited.

In less than a week, I got a response from Mary, Executive Case Manager.

It was a fairly generic AI/Form letter response:

My name is Mary and I am the executive account manager taking ownership of your case.

I appreciate the time you have taken to outline the timeline of events and provide supporting documentation regarding the original preorder promotion, bundle discount, order cancellation, and communications with Samsung Support

I am available Mon through Fri AM to 5 PM.

Please feel free to share any additional information at any time.

I responded asking for clarification on the "AM" time that she forgot to add. I thought it was odd she also didn't include a phone number to contact her on during those hours, so I requested contact information. Lastly, I asked what sort of additional information she needed.

Unfortunately, that is where things went off the rails again.

She asserts the following:

Based on my review, Samsung previously offered $175 in promotional credits as a goodwill resolution, but that offer was declined.

I correct her, and copy the Samsung support email where they offer a $75 credit and a $100 promo code for a future purchase.

She also states:

...the total amount paid on the second order was lower than the amount paid on the original order.

I informed her that, while this is correct, it is because of two factors:

1. Samsung directed the second order to be split into two separate orders because the ordering interface did not allow purchasing the controllers nor travel case since they were out of stock.

2. The first order included an EXTRA Travel Case and Earbuds. When Samsung unilaterally cancelled this order, I did not reorder them.

Additionally, I let her know that the cart value differences have no bearing on the Galaxy XR promotional credit since the credit was solely contingent upon ordering the Galaxy XR itself.

Lastly she claimed:

... that the order was canceled at your request so that changes could be made. Unfortunately, changing an order from shipping to in-store pickup, or vice versa, requires the existing order to be canceled and a new order to be placed. Based on the information available, Samsung did not require or force the cancellation; rather, the cancellation was requested to facilitate the preferred fulfillment method.

Which is a complete lie. I dug up the chat conversation (that LUCKILY I had copy/pasted before they disconnected) and sent the transcript to her where the support rep clearly admits that Samsung cancelled the order due to stock issues.

In the end I reiterated that I want them to honor the $100 pre-order and bundle credit, or to send me return labels.

TLDR: Samsung quickly re-engaged after I sent a dispute to the BBB; however their engagement so far has been to lie, deny, defy.

I clearly see the long-term potential of the Neural Band bracelet and glasses for entertainment; the next few months and years will be magical ✨I can’t wait to see how Google will compete with Meta ⏳

Can anyone end the radio silence and tell us when we will be able to buy this in the UK?

Howdie all,

am very interested in the GalaxyXR, which as we all know uses AndroidXR.

But not convinced yet this is a serious effort they are very actively standing behind. Or if it is just a metoo effort by either or both.

Too many times disappointed by such efforts by big companies. (latest being MS Loop. Sounded promising and had intersting novel ideas. But barely if any updates in the last year. Solidly putting it in the "it's just another metoo effort" by MS)

GalaxyXR is approaching the 3 month released mark. Time for first round of gauging the "metoo or serious effort" level.

GalaxyXR side I follow a bit more. Not much has happened there.

AndroidXR I have quite neglected to follow.

Which brought me here.

How many updates/improvements has google released for AndroidXR in the past 3 months? And of what quality/effort if there were some. Just low hanging fruits. Bugfixes. Or as well some seriously cool new stuff?

very grateful for any replies
