This is an issue now after bug 737199 which gives us our own InputReader. Doesn't seem to happen on nexuss-ics for some reason.
Created attachment 609530 [details] [diff] [review] Fix input handling on sgs2 Turns out this is a problem specific to the SGS2's insane multitouch driver and how our new inputreader code doesn't support it anymore.
Comment on attachment 609530 [details] [diff] [review] Fix input handling on sgs2 We need to track these patches to our import so that it's easier for us to update in the future.
