Sorry for bad news, but today I installed the september version on my Tolino FW10 ICS, and noticed first, that now I am able to control the frontlight intensity, after having disabled the use system settings checkbox (which was not working here with august version for some reason, only on Tolino FW12 Kitkat).
But then it occcured ... I wanted to see what the button Toggle in Frontlight menu does, clicked it and then the display was immediately black and the device remained completely hanging, I had to issue a system reset with the reset micro button. After restart device was Ok, but each Koreader start caused the same hangup and I had to reset the device.
Just to isolate, I did the following:
1. Uninstalled Koreader and installed again, but again the same picture - full hangup after first Koreader start
2. So it became clear, that there must be something wrong in the sdcard/koreader data, so I renamed this folder, reinstalled koreader again and it was working afterwards ...
Then I saved working sdcard/koreader also in another folder, just to see what is changed there on clicking of the Frontlight Toggle, and took also logcat from the koreader startup and clicking Toggle - see attached:
apparently last related activity was this:
D/FrontLight( 2137): Light====>SYS. brightness orig 0 conv 0
and then I saw on my PC screen capturing logcat, on each Tolino screen click, a couple of lines like event dropped :
Dropped event because input dispatch is disabled.
Then I reseted the device, copied both sdcard/koreader folders to PC, and compared - there are some differences in the settings.reader.lua,
both are attached.
At the end, I only copied settings.reader.lua from the saved sdcard/koreader folder to the current one, and next start of koreader worked like a charm
Attached is the logcat with the click of Frontlight Toggle button, with a
good and bad reader settings lua files
