Been trying to cut my phone usage even more lately. One thing that definately really helps, is setting everything to greyscale.
Phone's boring as hell now, and I only really use it now to look something up if I desperately need to.
It has also opened my eyes even more to the #accesibility of colour choice in web design. When everything you look at is in black and white, you can immediatly tell when a site designer never even thought about making the colours accessible to people with visual disabilities. Colour contrast really matters!
