I believe the stock email app (not the gmail app) that comes with the Vibrant has somehow been corrupted on my phone. I noticed that the email app was acting strange, then a few days later, I would find my phone very hot and nearly drained of all battery (this happened about 3 times). I turned off push for my three accounts (set them to "Never"), and I haven't had the overheating problem since. That being said, nearly every time I use the email app, I have to force quit it. Is there any other explanation for this, and if it is corrupt, how can I fix it?
