Dunno about the GS II which I haven't. No significant difference with my 7" Tab (old) even if of course keys are smaller. And I'm using Hacker's keyboard with 5 rows!

But there's something I don't understand and don't appreciate. Display is randomly oscillating between a greenish and a reddish tone. Not a bad contact, shaking the device doesn't change. But it is changing from "warm" to "cold" tones back and forth. What might be the clue?
