I've got a HTC Desire Z phone, and when it was still running Gingerbread this game worked flawlessly (and ate up way to much of my time). Since I upgraded to ICS, the game shows a weird bug: Every time I touch the screen, the game thinks I'm also pressing down in the lower left corner of the screen. If I drag an interface element (like the portrait of an investigator when assembling the team) it immediately shoots to the bottom left corner when I release it. During play, the inventory of the investigator opens or closes every time I touch the screen.
Using Dev tools I determined the screen doesn't register any presses in that corner, it's just something the game thinks is happening.
I'd love to see this problem solved, I need my mobile Elder Sign fix!
