I am preparing to use librem 5 as daily driver, so I have some questions

I will use it as my daily driver, so I need to prepare. I have some questions.

1.How to scan QR-code?

2.How to use it like compass? (I don’t think it is important, but it would be good)

3.How to use firewall? (I use AFWall+ on my android to serve my internet, so is there some alternative for librem 5? (I prefer GUI alternative, not terminal iptables))

4.Can I use mobile internet from my SIM-card? And can I enable/disable it in the top tray (or what is it)?

5.Can I use librem 5 for VR? (cardboard vr, youtube 360 videos)

6.Can I use it like secret camera, record a video with display turned off, I use secret video recorder on android. Or I think it would be good to have an option to just turn off the screen, without turning off something else. I’ve seen here, that display just turns off when you press power button, but I think it will be fixed

7.Also will I be able to use USB with OTG-cable?

8.And the last. Will I be able to share wifi like on android?

I would say that the phone is not ready to be a daily driver.

Most of the answers to all of your questions are no or with a big chunk of tinkering.

But they are real questions and the answers need to be addressed

i believe so - the L5 has an usb type C connector - so if your OTG cable is microUSB then you’ll need an adapter or a usb C one … i’m waiting to see some good open-hardware/free-software docking stations for the glorious convergence mode …

no. VR requires higher than 1080p resolutions for each eye due to the close proximity …

My mobile internet is working but I have seen posts on here about people who haven’t been able to get it to work for them. And you can disable mobile data. Not from the top tray, but from the settings app that you can get to from the top tray.

For all camera questions, I don’t think the camera is working yet. But if you are able to get the camera working I expect there are existing QR apps that could be used.

Yes, the WIFI hotspot is working.

USB host mode cannot be used without some manual fiddling right now, so OTG does not work out of the box. In general it is possible and it is planned to be enabled AFAIK.

1.How to scan QR-code?

I don’t think the camera is working yet. I stand to be corrected, but I think the best way to scan a barcode on GNU/Linux currently is with zbarcam from the zbar-tools package. Someone will have to write a GUI though, because zbarcam just spews the text content of the QR code into the standard output on the command line, without further processing to determine what kind of data it contains.

6.Can I use it like secret camera, record a video with display turned off

I don’t think that will be very difficult to achieve, assuming it can record video at all. But you’ll probably have to write a script yourself to turn the display off and on. Ideally you’d make it a feature of a video recording program, so that it can save a bit of energy by not rendering the video to the screen when the screen is off.

8.And the last. Will I be able to share wifi like on android?

That’s a pretty well-established feature in NetworkManager.
