It's been about 15 months, and I haven't really had to compromise or sacrifice anything: I haven't uninstalled any social media apps, my banking apps are all still there, I have contactless payments on hand, etc.. However, I can say with absolute certainty that my habits have changed _drastically_. Interestingly, I'm not even hesitant to use the phone when I need to, I use it all the time - but when I use it I now use it intentionally, and very briefly; gone are the days of catching myself somehow scrolling through instagram just because 5 minutes ago I opened a whatsapp notification from my mum. It's like night and day, and what's more I feel like I barely had to try.
This is obviously sample of one anecdata, but I'm genuinely surprised at how successful it's been. A real 'life hack'.
(And no I don't have any samsung coupon codes nor do I particularly care for them as a company. Worth mentioning though - the hinge on the zf5 is still really solid 15 months in)
