my s20 ultra's front camera always freezes when I try to video call someone using apps like wechat using 4G data, but only freezes sometimes when I use wifi. switching it to the back camera when it freezes usually solves the problem but when using 4G data it freezes after 30 secs ish...
not sure if it's the apps problem because i tried other apps and similar problem also occur, and i tried restoring the phone to it's factory setting the problem still exists.
hope if any knows what I can do to solve it if people run into similar problem or should I wait for the next update?
Are you experiencing these symptoms with all apps or specific apps?
Have you tried force stopping and clearing the cache and data for your apps?
Have you tried wiping the cache partition on your device?
Do you experience these symptoms with any of your stock apps?
stock app and skype seems to work fine, it's just third party apps that has the issue, not sure of it's a compatibilityissue or a hardware one, and I tried to restore the phone and erase all data, the issue remains
Were you able to complete all troubleshooting steps in the previous post?
Have you made sure all third-party apps are up to date that's experiencing this issue?
Try uninstalling and reinstalling the apps and see if that helps any.
Just to throw in that I am experiencing the same exact symptoms using WeChat 7.0.12, also on the S20 Ultra (SM-G988B QP1A.190711.020.G988BXXU1ATCH).
The front camera runs for a few seconds then freezes on a frame. Switching cameras back and forth allows it to resume, before freezing again after a few seconds.
I basically have not been able to use the front camera for video chats over a few seconds. The stock camera app has no issues.
The app has been locked in memory and battery optimisation disabled.
All apps and Android are up to date, troubleshooting steps completed, no resolution. I suspect some sort of aggressive power or data saving mode is responsible, but cannot find any further options available.
I have exactly thesame problem, my s10 Plus was fine but my s20 Ultra has this issue. Specifically my video freezes when making/receiving a video call in wechat intermittently, the other person's video runs fine. Video will run for an inconsistent period of time before it freezes someitmes immediately, sometimes after 20 seconds. switching the camera to rrar camera andback again fixes it but the problem starts again straight away.
I have deleted and reinstalled wechat, changed battery settings and tried different video settings. No improvement.
Just a quick update, I note tried on wifi and it worked perfected for an extended period. Problem came back as soon as I was on 4g. Not sure if that helps diagnose the problem or not. Problem doesn't occur on WhatsApp
