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
