Sorry if this was mentioned before, but I didn't find it in the previous posts.
My reader is a Kobo Aura 1st generation which is running a patched firmware 4.15.12920. When switching the Kobo on, the backlight is always on, but the backlight icon is not shown. In order to switch the light off I need to press the button 2 times: first to show the backlight icon (and also light gets a bit more brighter) and then a second press which turns the light off. Did anybody else notice this? And is there a fix for this?
