I bought 2 Kobo Mini’s off eBay recently, installed the Kobo Glo’s firmware (4.31.19086) on them so that they still can sync with overdrive loans etc following Kobo’s decision to removal support for them as senior citizens etc.

One thing I didn’t realise was that Kobo must of changed supply of the screen during the later manufactures, because there is a noticeable difference in screen contrast (blacker rather than dark grey e-ink) between these 2 units.

The older Kobo Mini unit N705292007390 has the less contrasting, almost fuzzier screen.
The newer Kobo Mini unit N705313010992 has the better contrast, much sharper screen.
You can see the difference in the photos.

Has anyone else with a Kobo Mini (still) noticed this?
