XPS 13 Plus 9320, again with BIOS 2.16.1: capacitive panel backlight too bright

Same, my 9320 Plus now at maximum brightness for function row key, when on outside daylight, it dimmed, so it work backwards, when ambience light normal, FN Keys at maximum brightness, on outside daylight, dimmed ..

Pls Fixed this issue ASAP, i cannot downgrade to 2.14.0 which working well, Thank You

And it is not possible to downgrade? I tried to downgrade to 2.14 but the downgrade is blocked for "security reasons". However, I really can't work with the keyboard like that, I'd rather be hacked than having to suffer through this considering that it is both my working and personal notebook.  Plus, it's a pain in the eyes in the evening and I can't watch movies because I'm constantly distracted by the capacitive panel that turned into a flashlight. How could dell mess up so bad? I mean, don't they test their softwares before releasing them?

@ale_hellstroem​ I covered the capacitive panel with thin paper reducing emission of light. So I can still use the laptop in a comfortable way. But this patch makes the laptop look not very professional.

@laptopper49201b​ thank you for the advice, I'm doing the same for now so at least I can use the notebook, but that's unbelievable. It's really unacceptable that we have to stick a piece of paper on our 2000+ € notebook because Dell released a broken upgrade with no possibility of downgrade. And they are not even providing a fix for this!

Thankfully just saw this before upgrading. @DELL-Nat M in the existing thread (as mentioned above) for this you advised that Dell Engineering is already on the case and working on a fix. How is the release of 2.16.1 having the same issue explained?

Thanks 

FYI - Dell Engineering is already working on a solution, and we’ll share updates as soon as we have more information.

@DELL-Nat M​ Fortunately, I also found an article where someone is facing the same issue as me. I'm using the XPS 9320 and encountering this problem as well. I feel a bit 'frustrated' because of these issues after the BIOS upgrade. Moreover, after the update, the keyboard backlight only has a 50% brightness setting instead of the previous 50% and 100% options. Dell needs to release an update soon to resolve these issues.

I wish I wasn't too responsible in updating my precious and very expensive laptop ¯\(°_o)/¯ Now that the panel is too bright it looks like it was bought from a chinese dealer who sells fake laptops. Or worse, it looks like it IS a cheap laptop. Which definitely is not. DELL HEAR US.

Not sure what is more concerning, the time that goes while this is still not fixed or the fact that this specific issue happening in the first place means that there is either no regression testing happening whatsoever or it is just there to list the issues and then go ahead with the BIOS release? 

I was planning to get another XPS laptop soon but after this I'm reconsidering.

@dmscg​ now I get why people like macbooks so much. You never have to deal with these <Profanity is never needed nor allowed on our Forum. DELL-Admin>. I thought that I would be safe at least with Dell's flagships, but apparently we were all wrong! Never gonna make this mistake ever again

If you have upgraded to the latest BIOS and experiencing the issue, contact Technical Support by clicking the blue "Get Help Now". They will first verify the ownership and warranty status. Then they will provide the next revision of the BIOS based on “Dell Pre-Release terms”. Note: Once you agree to the Dell Pre-Release terms, they may take up to 48 hours to share the file with you.

Has anyone here had any luck with the "solution" proposed by @Dell-Chris M? Technical support keeps ignoring me, and I'm wondering if the new BIOS really solves this problem and it's worth keep bothering trying to get it or if I should just give up

@ale_hellstroem​ The pre-release BIOS solved the issue for me. As the terms don't allow to distribute it, one must keep trying with the technical support. Eventually it helps to mention that it is internally provided by the L3 support.
