I know people have had this issue before but none of the solutions worked for me. It's always flashing unless I turn off my phone. It doesn't react to me blocking it so I don't think its actually on, just the light. I don't have Always On Display on so it's not that, and I haven't downloaded anything that's asked me for my camera or phone so I don't think it's malware or whatever.
Do you have facial recognition turned on in your settings for your lock screen or biometrics?
If you turn of facial recognition do you still experience these symptoms?
I have the Galaxy s10, I updated the system yesterday and ever since there head been a green light blinking. I do not use facial recognition or the always on feature, and it is constantly blinking whether or not I'm making a phone call.
@userAV7eBaHLYW Do you experience these symptoms if you test your device in safe mode?
