[Akanero]

Can someone post a link to the small button version? I'd like to try it out.

Looking into log while in landscape I see that the Amazon cocde does not work as it should:

winmgr[1166]: W ligl:fbioctl::Something wrong happened when trying to update
mxc_epdc_fb mxc_epdc_fb: Update region is outside bounds of framebuffer.Aborting update.

I don't know exactly how they implemented no-refresh page draw but my thought is that they are using a buffer that is bigger than screen and just "move a viewpoint". And after 6 pages it has to be redrawn completely. Amazon code detects this situation correctly while in portrait, but fail while in landscape.

I'll use for a day or two to make sure it works and then create a script.

As most of you should know already: Won't work if you install the 5.0.3 update.

The launcher itself, yes. But the screen orientation isn't changing when e.g. one of the two landscape modes is selected.

Any fix for the 5.03 upgrade?

Does it change from the command line?
What happens if you log as root via ssh and type:

lipc-set-prop com.lab126.winmgr orientationLock L

(repeat with U instead of L to go back to portrait)

great work!

but there is a problem:
Display a upper half page of pdf file in landscape mode, then zoom out, you'll get the zoomed lower half of the same page, and cannot switch back to upper half untill zoom the page back.
i.e. you could never zoom out the upper half page of pdf file in landscape mode.

No, the display doesn't change it's orientation when I execute this command (from a root shell access).

Damn it, i knew that they were fixing it but didn't thought that fast..
will not have a pc till tomorrow (gmt+1), anyone can get the 5.0.3 update file? so we can work out what they have done to what files?

[yifanlu]

I've already gone though all the patched files, patched java classes, and patched kernel. There isn't much. https://www.mobileread.com/forums/sho...37&postcount=8

Get the update from amazon's site.

They did not remove screen rotation code. It should be easy to fix.

Any clue on why it stopped working so?
