Oh, thanks :-).

Phone was probably water damaged. I can see probably salt at two places on top of the borad. One image is from components around WiFi/BT and other image is different side of board - bellow front flash diode.

I think you need to provide some background information. Is the phone water damaged? Does it turn on? Any serious drops?

is that not a soldered shield over the top

It is soldered. But what is under?

And can malfunction of this component be reason for no-functional phone?

@fbituco you'll find your BT/WiFi under that EMI shield. Could be a reason for non-functional if your BT or WiFi is not working. You'll have to give us a bit more information about what is not working on your phone.
