Using ADB with Fairphone 3

[agrapheuse]

Hello everyone,

Context: (feel free to skip)

I am a very new user of Ubuntu Touch and I just installed the FP3 version by following those instructions.

Thank you for your work, it works pretty well

I tried using an usb hub and I could successfully connect both a keyboard and a mouse to the phone.

My usb hub also has a HDMI port which I tried to connect to my monitor, unfortunately without success. (If you know of a way to workaround this issue that would be amazing)

Therefore, I wanted to give a try to use mirscreencast and I followed those instructions.

I would like to stream the screen to my computer using adb.

Help needed :
I am unable to see my device using "adb devices". I tried following those instructions. That is, I found both the vendorId and productId using lsusb -v and added them to ~/.android/adb_usb.ini. I also enable the About>Developer Mode>Developer Mode setting.

Any further steps I could take to try to have adb working with my device?

My adb version is

adb version
Android Debug Bridge version 1.0.39
Version 1:8.1.0+r23-5ubuntu2
Installed as /usr/lib/android-sdk/platform-tools/adb

Thank you!

I actually didn't check the device page for more info.

It seems adb not working is a known issue.

Are there any known "workaround" or is there an issue to track this where I can cc myself?

So I successfully managed to display my phone's screen through SSH using mirscreencast. However, with usb connection or through WiFi I experience a 5-7 seconds latency, which means I can't really use this to have a desktop experience. I wonder if using adb would help with the latency.

So far, the more "desktop-like" experience I get is to put my phone in landscape mode and connect through usb my keyboard and mouse. Side-note: I noticed that sometimes the mouse does not get recognized anymore and I need to restart the phone.

It would be really awesome if there was a way to connect a monitor, let me know if you know of a way to do so

Nit: another small observation: my usb hub normally accept a usb-C charger to charge the phone. However, if I connect a usb-C charger to the usb hub, then the keyboard that is also connected to the usb hub stops working (charging works though). So I have to choose between charging or connecting a mouse and keyboard.

I just tried out Anbox and it seems to be quite unstable for me. As using apps like Whatsapp is really needed for me I unfortunately will have to revert to Android so I will mark this question as fixed.

However, I am quite impressed with Ubuntu Touch in general, keep up the good work! Once Anbox works reliably I might get back to it.

Couple of observations:

• In order to install UB I had first to revert to the original FP3 OS link as I had installed LineageOS before
• As specified on the phone page, adb and camera did not work
• SMS and mobile data worked with custom APN for internet
• USB connection through USB hub to phone and keyboard works
• HDMI connection to a monitor did not work for me
• mirscreencast through ssh works but with big latency
• Anbox was quite unstable, Whatsapp booted on a black screen and Signal booted but I could not set it up
