Colour matrix showing on lock screen

[Y-Gotsan]

When I lock my screen it goes off but then shortly after it lights up with the screen displaying a rainbow of colours like when selecting a custom colour in an app... 

How can I stop this happening?

Go to Settings- Display- Screen saver, and turn it off

Hi @Y-Gotsan

Sound like you have a screen saver set on your device. 

To turn this off go to settings > display > screen saver

From here you can select photos so that the screen saver is photos rather than the colour screen you have, or you can turn it off by tapping the slider button at the top of this screen. 

Let me know how it goes
