NFC problem

[JHBN]

Hi to all:

I have a SONYXPERIA Z1 COMPACT. Some days ago, i sent to repair my xperia and the technician changed the battery since that the NFC does not work. I run the NFC Diag test in my xperia has the same mistake "Swp...No NFC SIM Detected".

The tech give a the old battery that has a sticker (or NFC tag) that my new battery does not have. Please confirm if for solve this malfuncion of my Xperia is neccesary to install that tag?

In the other hand, I think that the quality of that batteries are too low due to i had to change it and my xperia dones not have 16 month of use.

Please a response about that.

I'm guessing the NFC tag on the rear of the phone under the glass back hasn't been aligned correctly or it was removed as you have said and this is the reason - So I'm sorry to hear this but you would need to either return your device to the place of purchase or contact Xperia care and have your device inspected http://www.sonymobile.com/global-en/support/contact-us/
