Hi @matthieutc , thanks for another detailed bug report. I will log it for now, but honestly I don’t now if we’ll treat this as a bug for now, rather an improvement – as there will always be some outdoor brightness / sunlight which will prevent screen to be clearly visible. But I agree, this could be improved.
I know @Sandroid rejected the “wish” in favour of this “bug”, but not to overcomplicate, let’s just take it from here 
Thanks again for your support, we’ll let you know when there is a solution available.
