LP_ASUS100% normal, nothing gets warmer than it's supposed to. My guess is below certain point a temperature variable gets out of range and jumps from very low to very high value. For instance, if you try to subtract 00000000 - 00000010 (in binary, simplified) it may flip to 11111110. I've been in below 0°C environment for half an hour when I noticed this.
I can double check on the camera temperature spec, but I would assume so. Just don't let ice form on it.
That is an insane reading. At 130C you should be watching the phone melt itself through a hardwood floor. What kind of temps do you see on a regular basis?
Is this because you went outside on a cold day, or is this happening in your house?
