TL;DR
- Efforts like Graphene OS face increasing pressure from apps that refuse to run on non-standard Android.
- The custom ROM project characterizes Google’s approach to device attestation as incomplete and flawed.
- Graphene OS is prepared to take legal action if Google won’t let it pass Play Integrity checks.


I just want to buy a Linux laptop with VoLTE and be done with the product line “smart phone”. Unfortunately there is no such device (to my knowledge) and the only device that comes close is PinePhone Pro with docking station.
You can put a SIM card in some older thinkpad laptops with that upgrade option. There are services like JMP that give you a number and let you use your computer as a VOIP phone. I haven’t tried JMP but it always seemed cool and I respect that the software is open source.
Skype also has a similar VOIP phone line service. Its not open source like JMP and is part of Microsoft. But in this context thats also a good thing, skype is mature software with enough financial backing to have real tech support and a dev team to patch bugs, in theory. So probably less headaches getting it running right which is important if you want to seriously treat as a phone line.
There are community made projects for the framework laptop that add LTE using an expansion card
Agreed. I always loved the idea of the HTC Mini +.
Put the sim in your laptop, that’s the connectivity hub. The mini phone piggybacks the LTE connection so you don’t have to pull out your laptop for simple calls, texts, navigation or music actions.
