It is criminal that supercomputers in our pockets have expiration dates.
Even cheapest phone these days is hundreds times more powerful than PS2, has better camera on par or better with most feature phones back in the days and cellular/wifi. They can be used for detection, automation or just plain fun/gaming.
But no, you can't install Linux to overcome bloated, insecure abandonware (old Androids, iOS). Built-in, hot pillow of a battery that is pain in the ass to remove and even then it can't work without it.
In a broader context, it’s actually a bit of an oddity that computers had this brief moment of hackability. You can probably turn an old washing machine into a lathe, but it would be crazy for its manufacturer to even acknowledge this idea.
I understand. I got a Linux phone & its remarkably decent - its called Jolla
People are nuts, that's all there is to it. They're worried about thinness, but meanwhile buy phones that are so tall and wide they cannot actually fit in a pocket. There's no benefit whatsoever to the thinness, except that someone else's phone is thicker. And no, water damage is not a concern. You can absolutely build phones with a battery compartment that can safely be fully submerged in water.
