LPT: If you’re not a fan of where Android or iOS is going but have to use one, buy a used phone to avoid giving money directly to ill-intentioned manufacturers. Then use some of the savings to support Linux Mobile Distro development!
We need to show a market demand for repairable phones and unlocked bootloaders.
A good way to check out mobile Linux is through postmarketOS. They have a list of older android phones that the OS can be flashed on to and have a near mainline Linux kernel. I would just give the caveat that since it does not run android then you cannot use android apps unless you use something like Waydroid to emulate.
