C67ML Carta touch/screen issues?

[fonix232]

Hey guys!

Yesterday I had my Bookeen Odyssey Frontlight 2 replaced, and grabbed a C67ML Carta as a replacement unit, with the leather cover.

However I have two big problems:

- The display seems to be of lesser quality than the Bookeen - even though theoretically they use the exact same display module, the C67ML seems more washed out, more pixelated, at the visually same setting.

- The touch screen is pretty much off at the edges. I've enabled touch visualization, and it's very precise in the center, but the closer you get to the edges, it simply touches more inwards, at the end up to two fingers difference...

Has anyone else noticed these issues? If yes, have you found any solution to it?

Firmware is the latest Onyx stock one, 1.7.5_r1, from May 31.
