How to find when the device is first activated?

[him111]

Hello,

I bought another xperia z2 but I doubt that retailer sold me used phone. How can I make sure that the phone is not used and is first activated by me only. Is there any option online or ofline or from service centre which insures me that phone is first activated by me on the buying date? I want to clear my doubt before returning the product. Please help. 

Thanks.

You cannot do that,if the device was reset and repaired (formatted with PCC),everything in internal memory is gone. You might want to contact sony and see what they suggest:
