We have made the effort over an extended period of 4 Nexus to order 9 (also from other dealers, in a different color). Although we are not alarmists, all devices were affected by the problem - the lower left corner is always the biggest problem, since there often black is used.
Once you've discovered the tail light on the edge it reduces every time you start the fun of use. Also manufacturer HTC could offer me on my feedback only a new device.
Although the Nexus 9 would be the best tablet for us, I am sorry to say: hands off!
