@dobey said in Comparison of all kind of Linux Mobile Systems:
Updates from 16.04 should get pulled in daily to the devel images, in general.
Oh yes?! So all security updates of Ubuntu LTS are already been directly implemented into devel - and later into release.... Cool, didn't know that!
I don't know whow big the security advantage than is - compared with an open source (ONLY) mobile system, which probably never will have so many updates.
@3arn0wl Ok, didn't know. I use all of them - but only mobile.
A: Systems based on a PC-distribution
Plasma Mobile: plasma-mobile.org (based on Ubuntu 16.04 LTS, etc)
PureOS (only for future Librem 5?): puri.sm (based on Debian-testing)
Ubuntu touch: ubuntu-touch.io (based on Ubuntu 16.04 LTS)
B. Systems without corresponding PC-distribution (mobile-centric OS)
LuneOS: webos-ports.org (based on Open webOS (LG))
Nemo Mobile: wiki.merproject.org/wiki/Nemo (based on Mer/MeeGo Linux)
SailfishOS: sailfishos.org/ (based on Mer/MeeGo Linux (Jolla))
/e/ (Eelo): https://e.foundation (based on LineageOS 14)
[Android]
[IOS]
[ ] = Out of focus
@dobey Is there already an useful app which can be used on both (phone and PC)?
So for security issues it has advantages!? If somewhen the updates of Ubuntu LTS will be added to the mobile system as well!?
We could now have a long discussions if the future of an OS is an identical system which runs on all kinds of devices, which it is not from my point of view - but thats not the reason for this topic. I wanted to point out advantages and disadvantages or problems (like this one with android 9, which could in the future also be one for ut) of that what the market is offering.
But why ut is less mobile-centric? I don't find a lot about the core of Sailfish. Its based on Mer -> MeeGo -> Moblin, its middleware and should easily be adaptable to all kinds of devices: https://en.wikipedia.org/wiki/MeeGo
My first days now with the newest version of SailfishOS on the Sony XA2 are really impressive! In several stores with different quality levels there are masses of apps; the integration of android works really great, so even the android store is available and fast! (even if I not urgently need it). The system looks great and innovative, everything works also on a second view. So Jolla really does a very good job! Its the most developed system - besides the big two - as I see the things.
But:
With no other OS I had so many problems with the installation. Without Windows it was not possible - and an USB problem made it neccessary to use also a second PC. One phone got bricked because Sailfish is (until now) not installable on devices flashed with Android 9. Jolla stopped carrying out the system for a while and tries to find with Sony a way to reanimate such phones.
If I compare the funcionality of the browser and other standard applications like navigation, mailing, messengers or just weather information, I miss a bit the pure functionality of ubuntu touch. And especially the way to switch from one app to another, the solution on ut is for me much more handy. And at the end I would prefer some selected apps instead of masses.
By the way: On Sailfish there is an app called 'Crest'. Here you can see how many processes are actually running on the phone. Compare if the android support is On and Off. You see maybe 2 processes if its Off. You see more than 20 processes if its On - even if you haven't opened any app ever in your live. Normally the android support automatically starts and can be started only through apps, if you have stopped it.
PureOS can only be tested on a PC or you have to order future Librem 5. I haven't found a development for another phone which can be tested?!
LuneOS with a version from the end of last year can be tested on a Nexus 4+5: http://build.webos-ports.org/releases/doppio/images/
I will also try it 
Plasma Mobile: https://www.plasma-mobile.org/
Nemo Mobile: https://wiki.merproject.org/wiki/Nemo
SailfishOS: https://sailfishos.org/
/e/ (Eelo): https://e.foundation
PureOS (only for future Librem 5?): https://puri.sm/
LuneOS: https://pivotce.com/2018/11/28/luneos-november-stable-release-doppio/
I have installed nemo mobile on the Nexus 5+. And its running perfect. I haven't found problems (as a normal user). But it is nothing else than an old SailfishOS-version on basis of more open source components. So I cannot see more differents.
The newest version of SailfishOS is actually running e.g. on a Sony XA2 - for a Nexus 5+ it is not developed. And the XA2 is until now not part of nemo mobile.
/e/ is still beta (newest version: e-0.5-n-201905099519). As I know they actually work on their specific store and some major applications. They plan to buy phones and sell them incl. their system directly to customers during this year (this could be quite interesting because they also work inside a foundation):
https://e.foundation/e-pre-installed-smartphones/
/e/ is working fine e.g. on a Nexus 5 (and 4), you can test it here:
https://gitlab.e.foundation/e/wiki/en/wikis/device/hammerhead/info
or follow this: https://hackernoon.com/leaving-apple-google-e-first-beta-is-here-89e39f492c6f
I will come back to /e/ when the first official version is ready.
