BV9900 pro wireless coils centers location

Hi,

I am looking for the precise location of this phone's two wireless coils centers : the NFC one and the inductive charging one. I searched this forum and the web but didn't find any precise info.

These "sweet spots" are usualy marked on the back of a phone with an ad-hoc icon/symbol but not on this one. It is neither in the included manual. As this model is quite new, there are no "teardown" videos availaible yet on youtube and I wouldn't want to void the short warranty by investigating this phone's insides by myself.

I included a simple picture, BV only has to answer two XY coordinates... am I not quite helpfull ? ;)

And for the "why" part, it is quite simple : I am building a car holder with a spare Qi charger and an NFC tag and thus need to place these coils precisely.

With my regards,

Amaury

Thanks a lot Mentalis and Sebek73PL for your help.

I knew I should have learnt Russian at school ;) And for the thermal pic, I had tried with the phone itself in front of a mirror with no result, a second IR-camera prooves to be usefull.

With my regards,

Amaury
