SCRCPY with usb-c adapters over ethernet was not stable in my tests – PETER GAMMA (Director & Physiologist), MEDITATION RESEARCH INSTITUTE SWITZERLAND (MRIS)

I tried with three identical adapters and three Goole Pixel 6 Pro phones.
scrcpy over usb-c without adapter works also for me.
But with usb-c adapters it was generally horrible, as in the following example:

Genymobile/scrcpy: Display and control your Android device over ethernet cable works now

It rarely works, but it is not stable.
It requires first with Ubuntu to to connect your Android phone over usb-c to your Ubuntu PC
And then type:

• adb tcpip 5555

And then to use the ethernet cable. This requires two different wired connections one after the other.
This is also the information which can be found in the documentation.
This is a complicated procedure which only rarely worked in my case

I tested also an adapter which I bought for the Pinephone.
The first I tested was a cheap one for 10 USD.
The second I bought for my Pinephone is high quality and was around 30 USD.
The QGeeM USB C Hub for Macbook Pro Air HDMI VGA Micro SD Card Readers RJ45 Aux PD OTG Multi USB Hub Type C 3.0 Adapter for Notebook can be found on Aliexpress for 30 USD with different models.
The one I used was the one with an ethernet cable adapter.
It worked in one tests one using the usb-c plug on the adapter, which was great. But I could not repeat it and reproduce it. This usb-c connection over the adapter seems not to be stable.

android debugging bridge connected over the usb-c with scrcpy workedin one trial when using the usb-c plug on the adapter. But it worked only once and then failed.
This procedure over this adapter seems not to be well developed.
I previously did tests with SCRCPY, and the only method which worked to get it going after it failed was to completely reset the Android on the phone to factury settings

So I finally gave up SCRCPY over ethernet cable. It worked several times. But it is not stable. Maybe with a newer phone and fresh installed devices it could work, but not in my case with older devices.

An alternative is ADB over WIFI. I am against Wifi. But if it only used for SCRCPY it is not a big risk from a privacy point of view, since scrpy is only a copy of the screen

Over WIFI it is a similar procedure for ADB as over usb cable. But in my case the usb connection over the usb adapter with an ethernet connector was not possible in a stable way.
