Came after M54 update After M54 update, the sound became less and the screen light also became less. During the day, in the sun, nothing can be seen on the screen, while it was fine before the update. The update should improve things, but Samsung doesn't know what to do. It seems that Samsung Want to leave

Please try to check these steps :

Tap Settings
Tap Display
Disable Auto Brightness/Adaptive Brightness and use the slider to adjust the brightness to your preference
You might try resetting your phone if your screen is too dim to even modify the brightness settings:
Press and hold the Volume down button and Power button at the same time for at least 7 seconds to reset your phone.

Better than Samsung now there are other brands that are offering good charger speed Samsung still calls 25W super fast charge which is a joke with a customer. 😂😂😂😂
