The GGG shaders pack will bring out your world of Minecraft in a more realistic way. It might be a little bit too bright during daylight but this can be adjusted easily by using the brightness settings in Minecraft Pocket edition or on your device. However, you will see that the night is when the magic really comes out with the GGG shaders. All the lights look dramatically warm and combined with a realistic skyline, it really makes certain worlds look incredibly realistic. Cities atmosphere suit this shaders pack to perfection.

Recommended Settings for GGG Shaders
It is recommended that you set brightness to minimum in the Minecraft PE options. That should be enough. But if it is still too bright for you then consider dimming down on your device’s brightness as well.
