Camera could be taking pictures of QR codes to make it easier to set up a VPN.
Bluetooth could be integration with things like Yubikeys for authentication.
Dunno if that's what they're actually for, though.
Privacy has become a very important issue in modern society, with companies and governments constantly abusing their power, more and more people are waking up to the importance of digital privacy.
In this community everyone is welcome to post links and discuss topics related to privacy.
much thanks to @gary_host_laptop for the logo design :)

Best practices would not require camera permissions to scan qr codes.
Scan barcodes
Android includes support for the Google Code Scanner API, powered by Google Play services, which allows you to decode barcodes without declaring any camera permissions. This API helps preserve user privacy and makes it less likely that you need to create a custom UI for your barcode-scanning use case.
The API scans the barcode and only returns the scan results to your app. Images are processed on-device, and Google doesn't store any data or scan results.

I'm going to assume they didn't implement this because money. Their app runs on everything, from iOS to Android to Windows. Cost savings they likely just flipped camera permissions and didn't care about small edge cases like these.
With that said, Mullvad is a million times better, cheaper and doesn't require even an email or account creation to use. They created a system that effectively anonymizes the user before they even subscribe.
To be fair, they didn't offer that level of granular control for a while.
If you're a company with development prioritization that makes it difficult to say "we need to take a few weeks of not working of things that make money to reimplement something we already have that works, because of best practices that don't make us any money" then it can be really difficult to make changes like that.
You don't want to scan secure QR codes through Google APIs. You can be at risk of Google stealing the contents.
That must be a pretty new API, right?
Since 2015 it was possible with Mobile Visions API.
Now it's included in ML Kit
Wow, that's wild that I've managed to miss that.
Was it possible to run it sans-camera permission back then as well?
Thanks for letting me know about it, anyhow.
Ah okay that might justify the camera permission, although personally wouldn't see the need to have that.
Would definitely prefer to see it be an "as needed" basis, like ask every time
That is probably possible, since Android usually asks about that nowadays.
You can often just deny permissions and it will work fine, just nag you sometimes
I don't get why the entire world isn't on Mullvad.
I don't trust these guys at all. I trialed them and despite their full money back guarantee, they locked me into a support loop, always switching support staff with boiler plate responses and links that dealt with account issues or whatever. It wasn't until I left a stern reply demanding the refund or I would escalate the matter with the proper regulatory bodies.
It took 4 support tickets. To me, they came across hella shady.
they closed off Port Forwarding
I used to host my Minecraft server safely 😭 don't know any trusted VPN that has Port Forwarding
ProtonVPN still offers it I believe
AirVPN
You can set up a VPS and tunnel that to your minecraft server using wireguard some iptables magic if you're into Linux.
Dilly dilly, Mullvad is great. I prefer it over ProtonVPN just for how lightweight and simple it is
I know this isn't popular but I really like Nord. I've been with them for years before the ad campaigns that turned people off. Mullvad can use wireguard so I may look at them again at some point, but the Linux cli client for Nord is really solid and picks the fastest server in whatever region you like.
Wireguard is insanely fast. Like insanely fast compared to traditional VPN connections. For me that is an absolute dealbreaker they don't have it.
Once you start using Wireguard you can't go back.
What kind of VPN would need those permissions?
The one that Edward Snowden (yes, that one) publicly and explicitly called out that people shouldn't use. I won't rehash it here, but it's worth reading about.
Wait, are you the same guy I asked for access to your draft when you're done?
How is the paper going? Will you also be covering self-hosted VPNs in your thesis? Also, SSL-VPNs seem to be coming up nicely, so if you're interested in obfuscation, that might be interesting to you! Can't wait to read what you're cooking!
Hahah thats me! :P (lemmy is a small world) My main focus is most likely going to be free vpn's and the risk of using them. I have to limit the scope quite a bit and want to cover areas that are not that well properly documented... yet..
But thanks for the tips! I will defo read up on it and see wheter or not I can have a "alternatives" section towards the end.
Edit -> This research paper might feed your temporary needs :P https://www.usenix.org/system/files/usenixsecurity23-ramesh-vpn.pdf
Thanks, downloaded! Keep up the excellent work!
I use Express VPN and the camera permission is relatively new as I don't have it enabled and it's never asked me prior to enable it. I dug through the app and found it within their new password manager when you add a new credentials it offers you to help setup 2FA with the major providers and you can optionally scan a QR code with it so it's a benign convenience feature.
Bluetooth on the other hand I cannot explain unless it's to proxy any connections Bluetooth devices might make.
Not an endorsement of ExpressVPN, I've learned to avoid companies that sponsor on youtube. However, I believe you don't need the proprietary app to use the service, you could use a free software OpenVPN client such as this one.
They do offer support for OpenVPN although, unsurprisingly, they heavily push their proprietary client as the preferred way to use the service. This alone would be enough to discourage me from using it or recommending it.
There are Bluetooth FIDO security keys out there for 2FA, like: https://thetis.io/products/fido2-ble-security-key. Some implementations can also use a phone, running an app via BLE. Not sure if they use it, but that could be one reason it's asking for that permission.
Camera permission may be needed for scanning QRCodes to set up 2FA.
Dunno about Bluetooth, but isn't Expressvpn pushing their new password manager? I imagine it's a separate app, but if not, then it would make sense to have camera to read 2FA QR-codes.
Edit: from their site:
Keys comes included in any ExpressVPN subscription and is built right in to our apps for iOS and Android.
Yup, that's got to be the camera. Still not sure about the Bluetooth though.
You can have internet over bluetooth, both as a hotspot and as a tether, maybe that's the thing?
I prefer mullvad. Not only is their pricing and account system much more privacy focused, they are a European (Swedish) company and are bound by the laws of my country by default. Another European one is surfshark (Dutch) which I used before. I trust mullvad more though. They also have open source clients and had no user data stored when they were raided once before.
Edit: clarifying the reason I used surfshark. I used it back when I was in high school a few years ago, so their 3 year plan seemed like a very good price. They also supported this very obscure VPN protocol whose name I can't remember, and my school just so happened to have forgotten to block it on their network. But I couldn't use that protocol on Linux due to incomplete connection steps provided by surfshark, and I switched to using linux full time in the second half of my first year, so that was a waste and I just used my mobile data.
They also push the envelope on privacy, and frequently publish security reports.
probably qr scanning
bt for FIDO
FIDO can be done locally. Why external key?
In the mobile space, there are Chinese calculators apps on Androids by manufacturers that require internet access...
To be fair, the calculator on my phone has a built in currency converter and would need network access to get the exchange rates

Don't use ExpressVPN, they and others make money off of your data.
Yeah I dont, as I wrote in the description, im just researching different providers.

“Read the fucking post” lawl, the post says “I don’t use ExpressVPN,” and the person I replied to was like “Don’t use ExpressVPN!”
The intention wasn't to be a direct response to the OP, but to be a general statement of advice.
