Murtaza bhai its a very powerful and high end device 1080p. But I'm personally not satisfied with its battery timing. Aur koi issue nahi ha. I'm running official jellybean. And i hope Sony k camera ki apko btane ki zarurat nahi 
If u are planning to buy used one then ok but if going for new one then I'll not recommend u xperia S
Recommended sets in xperia are
Xperia T
Xperia Acro S
