Got an iPhone some months ago because it was cheaper than getting a Pixel or S24 and I hate it.
The apps suck, sideloading sucks ass because of both apple restrictions and the lack of modded apps, browsing sucks because the adblockers suck because the extensions suck, FOSS is pretty much dead of iOS, call spam detection sucks, keyboard sucks.
I never saw an ad on android for the past three years because of how good my setup was with modded apps and Firefox+uBlock but iOS is pure Advertisement Hell.
The OS visuals and responsiveness are better than most android skins but 60Hz is trash as well and 4GB ram means that I can not even open like 3 tabs at once without the others shutting down.
The photo management sucks the most. Any photo I save goes straight to my Camera Roll and has ZERO organization which memes no more epic funny memes are getting saved on my phone anymore.
The integration with Google Photos is also non-existent and images get saved only when I manually sync them and I will never buy iCloud because I hate the locked down apple ecosystem.
Modded apps also suck and nothing is as good as revanced plus the 7 day refresh limit sucks because of course apple wants 99$ per year to have the godlike ability to install your own apps.
Airdrop is maybe the only positive I remember about this. And maybe the battery life which is better than my previous phone's battery.
tbh since mobile linux (postmarketos and similar) is so niche and underdeveloped, and ARM (especially smartphone-oriented platforms) is an unstandardized mess of blobs, OP6 is the best device - it has the best support that is currently available for a powerful device. Good support also exists for pinephone and other linux-first devices, but they are much less powerful, while any other device with a similar processor (even the same processor) would have less support.
In particular, OP5T has less stuff working than OP6 and only three people listed as its users. So... proceed only if you really, really want to.
The proprietary hellscape that is phones.
