Hello,
I have the same problems as Peter. These camera resolution problems are present
online and on "cheese". Here are the test results:

You can find an attachment of Webcamtests.
Do you have any solutions?
Thanks!

Title:
Terrible resolution on integrated webcam on Dell XPS 13 Developer
Edition 9310
Status in linux-signed-oem-5.10 package in Ubuntu:
New
Bug description:
This seems to be a known issue, but I couldn't find any launchpad bug
corresponding to it. Apologies if I missed it, or if there is a better
place for reporting a bug like this.
When I try to use the webcam on my newly purchased Dell XPS-13-9310
Developer Edition, using Cheese (or any other app) on Ubuntu 20.04.2
LTS (fossa-bulbasaur X55), as it came out of the box, I only get a
very pixelated low quality 640x480 resolution instead of the
hardware's 1280×720 capability as advertised here:
https://www.dell.com/en-us/work/shop/dell-laptops-and-
notebooks/xps-13-developer-edition/spd/xps-13-9310-laptop
From what I gather, no linux driver exist that can use the full
resolution of this webcam.
I hope that it is somehow possible to get a proper driver from Dell /
Realtek. If not, I hope that Realtek can provide documentation for the
interface so that a proper driver can be written. I'm tempted to try
to make that my first contribution of a driver, but in all likelihood
I won't have the time or motivation to learn all that's needed and
actually write it.
Until a driver is available, I would appreciate if Dell would clarify
on their website that their 9310 Developer Edition can only use the
full advertised resolution in Windows. (I would not have bought this
laptop if I had known about this limitation, as I frequently use
Google Meet / Zoom and the current quality is not acceptable to me).
