First thing is nuke tap to pay. That is surveillance capitalism dependence masquerading as convenience.
Step one, and I am serious, is just use cash. Every time you pay with cash at a drug store, a liquer store, a casino, donation boxes, clothes, that is a tiny bit less information corpos and politicians can buy about how healthy you are, what causes you support, and how to manipulate you.
Just use cash, falling back to cash-purchased prepaid gift cards for edge cases like parking. You will pay more attention to how much you spend, you are helping ensure the unbanked can still participate in society, you are opting out of funding surveillance capitalism with your data, and at a busy restaurant you can just leave cash on the table and leave whenever you want.
From there when you are making a quick trip to the grocery store or something, just leave your phone at home.
Meanwhile, keep your phone in airplane mode full time. Use wifi when you must but do not use cell and see if you can go a month or two without actually having to be reachable every second of every day, but only when you choose to be on wifi.
Whenever you are connected to a cell tower your location is being actively documented and sold at all times, and even worse, you are mentally always ready to be contacted, for a new dopamine hit of information or a new decision to make. When it is off, and you know it is off, you can just focus on driving, on thinking, on processing the shit in the back of your head that wont go away on its own.
Anyway, once you are wifi only, and no longer dependent on your phone for commerce, its just a boring wifi tablet. Now, delete your least productive of your top ten ten most used apps every month until your phone is so boring you find you only use it a couple times a day.
At that point, tackle those final things like GPS and flashlight which could be handled by your own brain plus printed maps, paper maps, and an actual flashlight, a mechanical watch... and then you are free to move about the world comfortably without any electronics at all whenever you want.
People will ridicule you constantly for not having a phone, but those are just addicts feeling threatened.
