Hi, try to reset the device press and hold Power and Volume Down for 30 seconds to reset the phone. Also, charge the device using only using the genuine Samsung charger and USB Cable that came in the box.

I believe that he said he has already reset his phone, if he actually meant that he performed a Factory Reset? 

I know that some "night mode" apps can have a conflict with Samsung's Dark Mode setting, a Factory Reset should have resolved this.

Probably if the issue isn't resolved, he should visit a Samsung Service center if possible.

Well news for you did not come with charger

[RedDogRabbit]

Yeah, Samsung is cheaping out, & trying pathetically to claim it's for "environmental reasons" lol 😂 

Samsung says that people can use their existing charger, BUT Samsung doesn't get that many people might be first time Samsung owners, or have an older charger that doesn't have the proper charging speed.

Sounds like Samsung BSoD. This used to be easily corrected with removable batteries (which of course is no longer possible). There are some tricks for it, but not a guarantee it'll fix it.
