Upthread I mentioned LineageOS which I have phased out now except one device used to load public transportation NFC cards.
I had a Pinephone(allwinner CPU) when the SIM reader on my N900 died.
Since this year I have upgraded to a Pinephone pro(Rockchip CPU).
The experience on the allwineer CPU pinephone was a hot phone, slow browsing, and short battery life. The Rockchip CPU Pinephone pro is hot and short battery life but works quickly.
The heat and short life can be solved in software once hardware acceleration is implemented at OS level and CPU scaling is properly employed.
There are still things the N900 did better, mostly music playback and audiobooks which I could listen to all day, the Pinephone will get there.
At least we have all FOSS drivers so we can keep moving software and kernels into the future unlike the N900 which still has a few driver issues. The Pinephone FOSS drivers are also not tied to android and libhybris.
The modularized modem(not tied into the system and memory) and paranoia hardware switches(modem, wifi/bt, 2x cameras) are also a cherry on top of a project designed 100% for the user and not a phone company or a nation state.

Looks neat. I still cannot figure out, where are the files for making this qwerty keyboard slider case? I know it's Bluetooth, I would prefer to try USB, but first things first: where are the source files for this?..

Thank you. Best wishes.

Unfortunately, the Pinephones are gradually losing out to ex-Android phones (such as Oneplus 6/6T). Less and less hackers work on it. As a result, Mobian nearly dropped all support for it. Even postmarketOS has recently demoted it from the prestigious 'main' category it has been in for years. It is very likely that the next 'main' devices will be the Oneplus 6 or something else with that SoC (sdm845)

A large part of the PP drivers have been FOSS, yes, but in a manner that is not aligned with Linus' tree. i.e. a lot of those drivers simply could not be accepted into Linus' tree. The situation is a little better now, but there is still a long way to go, and with developers slowly turning away from the device, it will have to be seen how the long-term fate of the PP works out.

I am not sure why you would imply that the N900 kernel has not made it to the future ... Considering that you can just clone Linus' tree, and build that kernel with zero patches, and have it boot and work perfectly fine (which you cannot do with either PP model).

I maintain the N900 packaging in postmarketOS, and we really have only one patch for the N900 (to avoid a modem-related kernel oops ... i should actually spend more time on it so we just upstream it). The only non-working drivers/hardware is the Bluetooth (and FM receiver, since that's tied to BT). Everything else is working quite well and is very reliable too.

Of course the PowerVR GPU drivers are not FOSS, but they do work on latest mainline kernels. Instead of the state of drivers/kernel, N900 is simply limited by the aged hardware more than anything else, i.e. you cannot, for example, use it for browsing in any reasonable manner anymore.

For funsies, here's me running Linux 6.14-rc2 on the N900 (on postmarketOS with i3wm and tint2 for a bar)

You mean the 3d files that i used to 3d print the slider?

Yes, the wierd hardware with good FOSS datasheets but expectations for the community to do all f the dev is a problem. That and expecting the community to do all of the dev work on the CPU scaling leads to not much work on that and unusable as smartphone unplugged. Truth is the N900 getting all of the drivers now(good work!) is a result of reverse engineering old hardware. The Pine stuff is supposed to be open out o fthe box and is supposed to be chosen as such.
Is there full driver coverage for those ex-Android devices or is it libhybris?
I still have problem with using ex-ANdroid as the modem(which is owned by the provider once a SIM is inserted) has direct memory access.

In Europe many places there is not 3G anymore, but there is 2.5G (edge), but you have to pay for 4G connection to get it.

Did you use Pinephone (allwinner) with Maemo Leste? Because it is much faster than PostmarketOS. My phone does not get hot, but I have dip switced off wifi/bluetooth and front camera, and sometimes only use two cores. I have Pinephone Keyboard and that extend batterylife enough. Keyboard actually needed to get best points of Maemo. And Maemo is the best OS for Pinephone Keyboard.

Yep. 3D files for the slider, including the arrow keys. Bill of materials, and the like.

Which software do you use for CAD modelling? Because I often regard CAD software as either "useful, but a pain to use" or "pretty but seemingly useless". It's probably a question of steep learning curves and strange use cases. As in, I can open 3D file for mobile phone case in FreeCAD, but then I struggle to import Nokia N900 stylus onto the same stage/into the same file, or rather, struggle to scale it (by factor of 10, was it?)? Because it would be neat to have phone case that can store stylus inside. But then, I would need to figure out a nice, thin-end stylus for capacitive touchscreen, first...

And it's also a question of "Don't forget to take stylus out of phone case every time before you take case off the phone".

Thank you. Best wishes.

Hi,
Gosh, I kinda knew/suspected those kind of things but it's scary.
Do you mean: the RAM part of the memory or all the memory?
Who can access that, the phone operator?
What are some good places to learn more on thit subject?
Thanks

N900 between 2011(?) and 2022.
Since 2022, SFOS on Xperia XA2.
