How do I stop the screen dimming on Galaxy smartphone while I'm using the internet?

If your screen automatically dims or brightens, this is likely due to either Auto adjust screen tone, Power Saving mode or possibly the Adaptive Display screen mode.

 

Try adjusting each of these as per the steps below to adjust your device to suit your needs.

Power Saving modeClick to Expand

If you have your device set to Power saving mode, the device will adjust the screen for optimum power saving. 

 

The quickest way to turn off Power saving mode is to pull down the drop down menu from the top of the screen, then tap it on or off. (Note that you may need to tap the more button to see all the options)

 

On some devices (as below), you may see a Power Saving notification when you pull down the menu.

Depending on your device, the below screen will appear once Power saving mode has been selected. You will need to tap Apply to turn the power saving mode on.
