Apple India — Blue Color coating is going by itself

I bought my first iphone from apple store located in Bangalore, iPhone 12, 128 gb, blue colour at its first day launch date itself
After getting esim installed, it started heating issue
At charging time also it is getting heated also
Connectivity issue
That’s fine i was managing somehow but now the things comes that is not acceptable, now i can see that it’s blue colour coating is started going itself(see in edge)added pictures
Oh my God i can’t expect this before completion of 1 year
:(
Please replace my phone
