I am not sure if this is wort a Bug-report.
Today, I connected my Xperia 10 III to the USB-C-Cable I regularly use to connect a notebook to my EIZO EV3895 display (Connected to its USB-C-Port). This cable works perfectly fine to charge the notebook and display its output on my monitor.
However, my Xperia crashed immediately, and then rebooted into a boot-loop.
After I unplugged the cable, It would boot up again. I first suspected the cable could be the problem, and replaced it with a simple “charging”-Cable (USB-C on both ends, but only the data-lines for traditional USB 2 are connected). The outcome was the same, the phone crashed. I then tried the regular USB-A downstream ports, using an USB-A to USB-C-Cable, this doesn’t crash the phone, and it gets charged.
For comparison, I connected a Samsung SM-A520F to the same Monitor, It did not crash, it started to charge, and even acted as a USB host (I noticed because the xperia on the downstream port switched from charging to developer mode).
So, is this a bug of the phone, or is the monitor to blame?
