I'm living in India. Last year I bought my Nexus 4 in the US.

For a couple of months now my device is getting quite hot, and shuts down randomly. I have done a factory reset 2 times, but no use of that: the shutdown continues.

This mostly happens when I'm on 3g, but not when I lock the device to 2g. The problem started about 5 months after purchase, so it didn't exist from the start.

Has anyone experienced this issue? Can anything be done to solve it?
