Dell XPS 13 9333 Screen Brightness Issue

Hello,

Another issue with my new Dell XPS 13 (9333 Model) - for some reason, while charging or not, the screen brightness changes without me telling it to do so (it just did it right now while writing this sentance!!).

Any ideas on why this is happening? It's kind of like an auto brightness thing on a smartphone but much more random! It's really starting to really wreck my head.

Any help appreciated no matter how silly it sounds!

Cheers,

Richard
