Hello. Can anyone help me with detection of marked component from J5 Duos motherboard? Looks like somethink wrong has happend.. https://ibb.co/edYuWv

Thanks. Update (09/11/2017) 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.

@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.
