[SOLVED] I've been going round in circles with this. What worked for me was to visit the page for my tablet:
https://www.dell.com/support/home/us/en/19/product-support/product/dell-venue-8-pro/drivers, and use the Service Tag "Detect" method to download all outstanding drivers. I saved these to a folder, then ran them one by one, first BIOS, then Chipset, then the others (one was declined as 'older'). But this wasn't enough to get the camera working again.
So I went back to the Chipset driver (direct LINK), and chose this time to extract it to a sub-folder ("...Extract"). I found that if I asked Windows to search for a driver at that location it insisted the best driver was already installed. However, if I used the "Have disk" option, and forced it to use (in my case):
.. then it worked. To be precise: I updated the camera (under "Imaging Devices" in Device Manager) this way, then rebooted, but then updated each of the two "Camera Sensors" under "System Devices" in the same way, then rebooted, before trying the camera app. It worked, and I hope this will help others struggling with this problem!
Essentially, the trick is to overrule Windows' "discretion" and insist on the downloaded driver.
I have tried all suggestions given on this forum to no avail, the camera won't just work. Does Dell have no precise solution to this problem rather than allow buyers to suffer unnecessary to fix this issue or rather recall the product?
I downloaded and extracted the `Atom...` chipset files but Device Manager had nothing to work with to find the camera driver as `Imaging Devices` or any other possible category would not expand, as Windows10 found no new hardware.
I had downloaded the chipset before but did not install as I got the message that I had all the same, updated, files.
I adapted your advice and installed the whole chipset despite the warning that it was already installed. I rebooted; still no camera yet.
I went to troubleshoot Settings and scrolled down to Get Help (have a question) then entered my issue for which I might have typed windows cannot find my internal camera.
The Help/robochat screen came up and I skipped the choices and `entered my response,` which might have been `windows cannot find my internal camera.` At some point in the process I indicated I was using the Microsoft camera app, not third party. Three diagnostic options were presented. I made the `app` choice but this did not solve it (don`t remember the sequence of events) so the robochat suggested one of the other three choices,the `device` choice. The camera app popped up in front of the robochat screen and moved around to get my attention. I tapped it and there was a moment of that didn`t work then the camera came on. I went to the canera app from Start and it did work from there. I checked it out in the Skype AudioVisual settings and it worked but was upside down. I recall reading about this on my long journey so will seek to solve the Skype issuer now.
