Hi

I was wondering if someone can assist me with probably a simple issue.

During the night my phone is alway on charge and during the night I may receive a text message, whats app message or even emails and notice that my display stays lit until I manually press the power button.

Is there anyway in the settings I can set it that when its on charge it will dim the screen or switch it off.

When Its not on charge it performs fine.

Could it be I need to use an app to resolve this problem?

Any help would be greatly appreciated.

Thanks
