So I just got in my Nexus and first thing I did was install my Word Search for Kids game on it. The game works perfect on my phone, HTC Thunderbolt.
Every touch is registering twice. In my game you press letters to select them, and press them again to deselect them. Each touch causes the letter to highlight, and then unhighlight. It plays the sound for each as well, it's like I am double clicking it. Happens on every touch event.
