So, I'm outside a lot on the weekends at race tracks, and my phone goes nuts ONLY when I'm out in the heat for long periods. Has anyone else experienced this? It will sort of freeze, but the screen will bounce a little. It is frozen in the sense that it will not do anything. I am stuck on whatever screen I was on while the whole screen does this bouncing thing. I sometimes can't even shut the screen off. I end up having to pull the battery.
