Whoa, calm down. No need to yell. Most electronic devices generate heat when in use, and small handheld devices especially do when they’re charging or running a lot of operations. Unless your device is getting literally too hot to handle, I wouldn’t worry about it. Then again, we’ve all heard about the (rare) exploding laptop batteries and such, so don’t set it on a pile of toilet paper or dry twigs while it’s plugged in if you’re worried about it.
And if it does fry, I’m sure SanDisk will replace it. Keep your warranty card on file.
