The QUERY_ALL_PACKAGES permission (what an Android app needs to see all the packages installed on your phone) is a little weird. The user doesn’t get prompted and explicitly grant permission for it like they would for something like MICROPHONE- having it in the app’s manifest alone is sufficient to query packages. However, Google Play Console does make you submit a video of how the permission is used in your app in order to publish on Google Play if they detect it in your manifest.
The acceptance criteria made sense for our app (it displays your phone’s notifications on your smart glasses HUD, and users need a way of selecting which apps can/can’t display notifications). I don’t know how HSBC justifies it though.

We're going to be putting out a Mentra Edge SDK in the next few months, but it comes with some downsides. Using your phone as a compute device is a battery hog, and you can only connect one app to the glasses at a time.

It has always been possible, we've even seen someone in our Discord host it directly on their phone using Termux:

Hey thanks for commenting. Developers host their own apps - they don't run on our servers. See:

In your opinion, what do you think should change to make this an "actual" open source OS?

Mentra Live runs AOSP similar to the other AI glasses on the market (Ray-Ban, Xiaomi AI Glasses, RayNeo V3 AI Glasses, etc). It's heavy, but allows us to ship fast. You'll find this code in `asg_client` folder.
We're also working on a pair of HUD glasses that will release in 2026 using an NRF5340 MCU. The code for this is being developed in the `mcu_client` folder.

MentraOS is a cloud OS (there doesn't exist a good way to build this on the edge, we've tried). Users don't need our cloud service, however, as it can be self-hosted:

It's all open-source:

Hey, thanks for commenting, but this isn't true. You can check out our glasses compatibility list here:

We're also looking to support the Brilliant Labs Halo glasses once they release later this year.
Regarding Ray-Bans: We'd love to support those, but the Ray-Bans are extremely locked down. Nobody has found a jailbreak yet. We're always open to support more glasses provided they're all-day wearable and have an SDK.

In terms of all day wearable HUD glasses:
Even Realities G1 are the best HUD glasses on the market right now. They’re the first pair (with prescription) that I can wear all-day without pain, and without looking like a dork.
My team used to main the Vuzix Z100 glasses, starting with the Vuzix Ultralite reference design that predated them. We won’t touch them these days (and recently stopped selling them on our store).
Others… Meizu StarV Air 2 and INMO GO2: both lack public SDK, GO2 is too heavy. Brilliant Labs Frame: cool prototyping toy, awful glasses.
For “AI glasses” that have camera, no display:
You have the RayBan and a number of companies making these. The only one I can recommend is our upcoming Mentra Live (https://mentra.glass). It has the same camera sensor as the RayBan, but runs open source software & has an SDK.
For more sci-fi glasses that run Android and have display + camera, see the INMO Air 3, TCL RayNeo X3. These are too heavy to be worn as regular glasses, but are fun prototyping tools.
All these companies will exist in 2026. As for a 5 year horizon, I’d place my bets on Even Realities, and Vuzix (as a waveguide supplier, not consumer HW). Meizu and TCL will stick around as Chinese megacorps, though I’m 50/50 they will continue developing consumer smart glasses. Brilliant Labs is cooked unless they turn things around with their next pair of glasses.
Google & Android XR: I don’t expect their glasses to be competitive for at least a few HW generations at minimum. In terms of public information, we know they’re monocular and heavy (>45g), which is an immediate killer for the majority of users.

I have a pair - they're not as integrated as you'd think. It's essentially a BLE device that projects text/data sent from your phone, so any data transmission depends on the companion app you use.
Shameless plug: We build an open source OS for glasses that works with them. AugmentOS.org

This exists, sort of. I got a demo of these at a YC event a couple months ago and was very impressed. The back is opaque, though, so it's not real AR, but it does accomplish "E-Ink displays in a glasses form factor":

You don’t have to be incorporated for Azure startup program. Sole proprietor LLC works fine. It’s kind of an insane deal… $125k credits for a $150 LLC and a YouTube demo.

The Unitree robots look great in videos, kind of suck in reality. The motors in the humanoid (G1) overheat after shaking hands a few times, and the wheeled dog (GO2W) drifts like a broken RC car and constantly topples over in motion.
They also patched the known jailbreak methods early this year, so all newer models lack sensor access unless you pay Unitree massive $$$ for SDK access.
The base Go2 is a fun toy, though. There’s a high level web SDK you can use for free.

You can absolutely find more feature-packed glasses. Epson, XReal, Viture, Vuzix Blade, TCL RayNeo X2/X3, INMO Air 1-3, etc. The issue is all these weigh north of 70g (too heavy for comfortable daily wear), and/or require a wire that connects to an external compute box (not socially acceptable for daily wear). Glasses like the Even Realities, otoh, are lightweight, look normal, and are wireless, so can be worn all-day as you would normal prescription glasses.

Mentra here.
The Nordic MCU they use isn't actually the limiting factor, rather it's the glasses' firmware. For bitmaps from third party apps (like AugmentOS), they enforce 194 byte chunk sizes and do not support RLE. Their first-party app does not have these limitations. We're stuck with this problem for the G1, but we're working with hardware partners to make sure future glasses don't have these issues.
