Hi Sofiya,

That's a great write-up.

My mobile repair guy is attending my mobile (sony Z3- single sim) for antenna- it is unable to receive phone network signal properly. He says he has to replace the antenna mother-board. But from your write-up I don't find any such mother board- is my repair guy conning me?

Thanks

Sundar
