My phone will get warm randomly and I can't figure out why. When I say warm I mean above 90 degrees F...is this normal? It never usually goes above 100 but it's just odd how one moment it's 80 F while not in use and next thing I know it's warm and I haven't used it much it all. I am on Liberty 1.5 and use jrummy's overclock app, not overclocked at all and with low voltages. I'm getting great battery life I'm just concerned about the heat.
