Hi.
I have 1 Sony Xperia Z2 which I bought it few years ago.
Recently, The phone always show poor signal or even no service in some places especially at indoor.
There was once I compare my phone with an iPhone 7 with same telco and place.
Unfortunately, my phone shows no service while the iPhone shows 3 bars signal with 3G.
I went to Sony service centre in Plaza Berjaya to find out the price for a replacement.
To my surprise, they suggest to change the whole motherboard with signal antenna and the price is about 1K.

Anyone knows where i can send for replacement just for that signal antenna or with cheaper motherboard?

Thank you.
