I will ommit this release and wait for 1.1.9.x with SFOS 2.0 UI but those who are interested can check it out (taken from XDA thread)

Changelog: Alpha13 - 10 September 2015

• Play classic Android OpenGL games from APK files (no apps only games)!

• Android's virtual SD Card is now mounted on bootup, so all photos, videos, music are now visible in Sailfish OS apps!

• MTP transfer mode works (not thoroughly tested), just choose "PC Connection" in Setting->System->USB

• Sailfish OS 1.1.7.28

It works pretty well. OTA also works, but as the 1.1.9 GUI doesn't start on the N5, do not upgrade!

ota works? seriously ?thats good

Didn't I tell you yesterday on IRC ?? :-p

Yes it works, but that's a bit tricky procedure within the terminal. But for the moment, Lipstick (the GUI) doesn't start, so, do not upgrade.

ah yes but i means that simple ota works, you fool me saying half truth ahahahaa,just joking..hope it will work in an easy way

its fairly simple in terminal if I remember rightly, I normal stick it on devel and then its a zypper ref and zypper dup

sorry but i am real noob in this things. until now i have lived (tecnollogically speaking) eating fast food os (just to eat)

It's a bit more complicated, but yes, that's the big picture. Thanks to alin on IRC, I've a working GUI, but almost no sensor, only the proximity and ambient light seem to work as expected. No GPS, no accelerometer, no rotation, etc.

think i buy tomorow a nexus 5 too, hope someone will port SFOS2.0 to Nexus

Jolla did ages ago. How much of their work we will ever get the benefit of is unknown
