My Samsung M30S recently had the Android 10 Software update. Soon after that, I've been having this display problem where the screen automatically dims after around 5 seconds, and gets back to normal with a tap. This particularly happens in YouTube, Instagram, and while viewing document files everytime. It is very annoying, especially while watching videos. Addaptive Brightness is off. How to fix this?
This is Probably the Screen Time out. And you must have the Battery Saver On i.e "Power Mode" disable it. Or try to Set the Screen Time out to 30s or 1m. Hopefully this will help.
Please perform the below mentioned step to resolve the issue:
Check device in safe mode to perform that power off the device for that press and hold the Power key for one or two seconds to turn on the device, when the Samsung logo appears, press and hold the Volume down key. Kindly exit the safe mode by restarting the device.
