Well,
another headache now.
first the camera lens coating started peeling off.
And now the back panel (metal body) coating has started peeling off.
It's shame that this phone has a price tag of 28000 INR and has won a Red-Dot Design Award !
Sorry to hear about your phone,
I recommend you to contact your local support for further information
on how to send it in to a repair center for investigation:

Thanks for the reply.
I am planning to take it to service centre tomorrow.
will update what happens. 
All the same things happen to me as i have black color first of all camera lens coating started peeling off and then back body panel color peeling off.......
Well,
All service persons are same.
Cosmetic defects are not covered under warranty.
It's not even 3 months since i bought the phone 
yeah.
For Xperia S display issue, Sony offered replacements as number of users reported it.
But Ion user base is itself very little. So not many of them will report, and thus they won't offer any replacements. 
C'mon man this is Sony and it will never change and never satisfy his customer.........Sony will be always sony and i will not buy any sony product in my entire life.....xperia ion is my first & last sony devce.
