       | 
       | It would be great to know how it compares with other DIY phone
       | projects like ZeroPhone.

           | My experience with open source linux phones is that they can

           | distinct base operating systems. Some can make calls, some
           | can receive sms and some can suspend resume. None can do all
           | three. If they'd picked one standard approach they could have
           | all those things with 10% the effort I've seen go into those
           | ecosystems.
           | 
           | I don't think there's anything particularly hard about
           | producing an open source linux phone with modern hardware and
           | a supported base operating system that is competitive with a
           | typical dumb phone.
           | 
           | However, none of the companies that have tried to make an
           | open source phone are product focused enough to build such a
           | thing.

         | The word _just_ is doing a lot of work here.
         | 
         | E.g., you want graphics acceleration.
         | 
         | That means you want work done in Mesa so that the GPU in
         | question is better supported than it currently is.
         | 
         | But you _also_ want Firefox 's Webrender changed to allow using
         | the GPU in question under Linux, by default. Otherwise the
         | browsing experience is laggy as hell for everything other than
         | HN. That means lots of testing in Firefox, and somehow
         | convincing them not to blacklist your GPU under Linux. (Which
         | I'm guessing takes time since changes in Mesa don't hit every
         | major distro all at once.)
         | 
         | And you _also_ need video acceleration to work out of the box.
         | Otherwise you 're going to be trying various flag combos just
         | to get your phone from getting hot while watching a video. And
         | then your browsing experience probably gets laggy again.
         | 
         | And then you're going to need to rinse and repeat that entire
         | process to get the baseband to work with nearly any carrier, at
         | least in the U.S. They probably aren't going to support using
         | _that_ baseband on something that isn 't an android phone.
         | You'll need some reliable way around that. Is this an open
         | research question? I don't know.
         | 
         | Once you have those done, try to figure out why playing music
         | to a bluetooth speaker over this device sometimes changes the
         | pitch of the audio! Oops, another unexpected rabbit hole.
         | 
         | I declare by fiat all of the above problems have been solved.
         | 
         | Oh no, I forgot about battery life.
         | 
         | Now I've got a summer project to figure out why suspend
         | sometimes-- but not always-- freezes my phone.
         | 
         | After that I need to figure out the signal path between
         | baseband and Linux to figure out why getting a call sometimes--
         | but not always-- wakes the phone so it rings reliably.
         | 
         | These are all hard things. The idea that motivated rando open
         | source devs can roll up their sleeves and solve phone
         | _usability_ is laughable.

         | Problem with a non-android thing is that you lose the software
         | platform it gives, as well as the ecosystem of apps. To do a
         | new thing looks time consuming - the hardware and firmware has
         | to be solid, the UI can't just be a desktop Linux in fancy
         | dress, and then you need to write apps for stuff.
         | 
         | I sometimes think through doing a garmin-type thing with an
         | e-ink display and the features I want - it works out to need
         | way too much time: well-integrated hardware, decent low-power
         | firmware, then the interface and custom map software is just a
         | bit much for a spare-time thing for me (a pick one or two sort
         | of deal). Android solves at least the ui and app problem in
         | that case.
