Honestly, if we could upgrade the RAM in phones, I’d probably be fine with this one for a decade. (Or until they start making phones with qwerty keypads again.)
There’s a lot of fake SD cards on the market, worth checking it before putting anything important on it. I find that if you can put more than eight gig of data on it without it getting corrupted then it’s probably real

Congrats! And holy shit, having a way of upgrading RAM in a phone is something that never crossed my mind! This would extend life of phones by so much.
There’s no reason why at least the motherboard couldn’t be a replaceable module if one is happy with cameras and display, or the other way around. Not saying it has to be super simple like plugging in a Lego module, but it’s definitely doable. Most peripherals are borderline off the shelf anyway and their functionality and support is mostly in software.
