Xiaomi Redmi 1S gets too Hot, Any fix

I recently bought Xiaomi Redmi 1S from Flipkart. Without installing any third party application into it from PlayStore it is getting hung and more than that it is getting HOT. It feels like it is burning. I haven't installed any heavy application into it but still. All the applications residing on it are factory loaded and still it gets hot. Please suggest any fix.
