the vast majority of commenters here either have no direct experience with a Linux phone or have seen some shallow youtube "review" of a dude swiping the same two screens left/right and extrapolate a buncha shit that has no contact with reality.
presently, and in the foreseeable future, linux phones aren't an android alternative, they are just linux on the phone, i.e. they allow you to do linux shit on a handheld device.
like, the bleeding edge version of any variant (plasma mobile, gnome, phosh) isn't even close to an Android phone from like 2015, let alone a modern one.
and that's before we touch on the pillars of mobile tech like fluidity, battery efficiency, reliability, etc., none of those things are even in a remotely passable state, not to mention - using the thing to make calls. you are better off forgetting about the camera, as well.
and the reason is simple, not only is there a gargantuan discrepancy between evil corp's resources and the predominantly unpaid enthusiasts, each dev team's reimplementing shit that's already solved on another platform. apple doesn't have to do that. google as well.
then there's the idea that the javascript-backed Gnome - that has issues running fluidly on super-capable hardware - is the basis on a low-power device on which the linux mobile phone experience is built. reinventing solved shit, but in a stupid way - THREE FINGER swipe on a phone, really?
although there's a solid app base, the apps that are supposedly mobile friendly are few and far between, most are just downright unusable on a vertical screen and dog help you if launch an electron app. firefox, even with pmOS patches (useless without) is tiresome to use. you can forget about dating, ubering, banking, or even just using a messenger everybody else does.
if you're squeamish about flashing custom recoveries and ROMs, the e.g. pmOS install process is way, way, way more involved and failure prone. if you go with ubuntu touch or mobian, even more so.
finally, if you're talking about a device that you've grown accustomed to to the extent that you're using it subconsciously, swiping and multitasking and such whilst walking and dodging other pedestrians - no such thing exists over here.
I'm just tying this up because I keep reading about "switching", people are either delusional or misinformed, there's nothing (yet) to switch to.
get a couple of $50 ex-flaghips to play with, flash lineageOS on one and pmOS on the other and that should hold you over for a coupla years.
