hello friends! I have a Kobo Glo and I found it a wonderful device, it's really fast and have a great high resolution.
I have noticed that on the bottom of the screen, only when I turn the light on, I can see some kind of dark-yellow areas. those areas are only on the bottom. they are not super heavy but I do not like this. I wish to ask to you: is this a defect? what is his name? do the warranty covers the problem?
this is my sketch (I have not a camera), it is extremely exaggerated:
