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).
