Sadly not anymore because I need my banking apps to work reliably. Making them work isn't the biggest problem, but I'll never know when an update blindsides me and breaks something.
On a sidenote, I'd really like to know why banks think that an ancient phone that hasn't seen a security update in years is somehow more secure than an up-to-date Lineage or GrapheneOS.
I would love to run Graphene OS, but their stance on root ("REEEEeEEeeEeEeEeEEEE iTs nOt sEcUrE aNyMoRe wHy WoULd yOu dO tHaT" Jesus fucking christ I'm aware of the risks now stop being a little bitch about it) drives me up the fucking wall.
Aside from the initial install is GrapheneOS a simple forget about it type of experience, and no fiddling around with safety net or whatever so someone with no technical experience can be given it and use it and stay updated?
I wonder if one possible alternative is getting an old iPhone and Apple Watch and using the iPhone just for setting up and updating the Apple watch. Then use Apple Watch for Apple pay. You don't seem to need any data to use it for paying https://discussions.apple.com/thread/8204935
I think if that works going full GrapheneOS for a degoogled smartphone device and a smart watch for paying might be something I could do.
Eh, banks don't want to piss off their customers over something they have less control over.
However I do know that my bank does keep Android version updates in mind. The app won't work on anything less than Android 10, which is about 4 years old. So no working on any kind of ancient phone.
