@nemo@mas.to @ferricoxide@blahaj.zone To reply to both.
Yes, hardware compatibility is a huge issue. Not to mention prices.
Ill just mention my personal setup instead.
A non used 2018 oneplus phone, around 200 euros.
Has direct LineageOS support, and unlocking the bootloader is as simple as clicking 1 button in the settings.
Flashing LOS was also fairly easy with fastboot, then, magisk setup, aaand all the apps one might use on the daily. Fully de googled.
Solid hardware specs, has all the little features i enjoy, up to 1 terabyte external SD card support, NFC, standard earphone jack, etc.
As for apps, anything FOSS. From calendar, to clock to file manager...
If youd like me to list google alternatives for stuff like email and such, feel free to ask :3
idk what else to say
