Interesting. Thanks for your answer.
Does app removal help you? There is a lot of hype near 'Digital detox'. Did you try it?
Facebook is an app that I never installed, but I can not keep from going on it through my browser, even though I gain nothing from it. I would love to find a way not to browse it anymore. I have not tried any digital detox on smartphone. I can not really judge it.
I have decided that I will buy a bass guitar this week-end so that I spend less time on screen. Low-tech solution.
