Camera works fine, except it won't transmit video in Teams
This problem is baffling me completely, and I've worked in IT Application support for almost 40 years. I hope someone can help me resolve it. A family member has a very important family court hearing to attend via Teams in a few weeks so I'd like to help her out.
This is a Lenovo laptop (Ideapad 330S-14IKB) with a built in SunplusIT webcam. The camera works perfectly in Google Meet and Zoom, but not in Teams. I can see my own video feed on my screen but the other Teams meeting users cannot see my image. The camera is enabled in Teams.
Some things I have already tried:
- Updated webcam driver from Windows
- Updated webcam driver directly from Lenovo site
- Ensured Windows 11 is up to date
- Checked privacy settings to ensure Teams app is permitted to use camera
- Uninstalled any other apps (e.g. Zoom, Skype) that may be using the camera
- Cleared Teams cache folders and restarted
- Uninstalled and reinstalled Teams
- Performed a partial Windows reset, retaining user data
- Performed a full Windows reset, erasing the hard drive
Some other symptoms and things I've noted
- Camera works fine on my own Teams window and I can see my own image
- Camera transmits video correctly when the other party is on Android
- Camera stops transmitting video when other party is using Windows
- The same problem occurs using Teams in a browser web app, with either Edge or Chrome
- Screen sharing works fine
- Camera works fine in Google Meet (web) and Zoom (app)
- The problem persists if I log into the laptop with another user account
- The laptop has a fresh install of Office 365
What on earth is happening and what else can I try?
I'm very technical but this has beaten me!

Trouble Shoot and Remedy to Laptop Webcam Undetected Error (No Webcam)
Remedy/Solution:
(1.1) Mentioned by other contributors online and Microsoft Community.
My Personal Experience:I encountered this issue with Laptop Camera (Lenovo S340, AMD Ryzen 5 3500U, 14") for several years, until I saw a post on Microsoft Community, with a solution to root cause on why laptop webcam was not detected.
Just by using 2 fingers (thumb, and 1st finger), by "pinching" or "pressing" area beside laptop camera, on external side and internal side of screen frame, the problem can be temporary solved (minutes, hours, days, weeks).
It could be a hardware issue of Laptop camera wiring or electrical contact issue (eg. loose contact). Very often, a laptop user may open the screen on either left side or right side, of screen, this may cause the screen frame to "Warp" (physical bending or twisting of an object). If user were to open laptop screen carefully, by opening laptop screen in the middle of screen, such issue could occur less. Screen frame "Warp" may cause laptop camera to encounter electrical contact issue, resulting in Webcam Not Detected, or Black Screen, etc.
Troubleshooting Windows software in this case may not solve Webcam Not Detected, Black Screen.
I had sent my laptop to Lenovo's service centre for 1 or 2 times for above problem, but still not solved even after reinstalling Windows 10 and other software. I heard similar issue for Asus laptop, and had informed a staff at their motherboard service centre on above remedy, during last visit.
(1.2) Buy a USB Webcam, and install on laptop's USB port, preferably from reputable brand, with driver software that can be recognized by Device Manager (eg. hardware name + brand + model).(1.3) Compatibility issue, with both hardware and software. It could happened to product of same model, but different unit/piece, eg. hardware of same model but different individual piece may have compatibility issue with motherboard.
potatan I seem to have the same problem, but I'm using an external camera. Camera works fine in other meeting apps, and I can see myself in Teams meetings, but other participants see a white screen.
Windows 10 Home 22H2 Build 19045.4046
AMD Ryzen 9 5950X 16-Core Processor
NVidia GeForce RTX 4070 Ti
Intel(R) RealSense(TM) Depth Camera 455 RGB
Any solutions out there?
