My P30 wifi, Bluetooth, GPS are not working

Few months ago, I came back from work and its raining. My phone in my pocket is also wet and caused the camera lens to vaporized.

I have already open my phone and Clean it with Ultrasonic cleaner + 99% isopropyl alcohol.

My wifi works but in weak condition. My bluetooh and GPS also very weak.

Should i open all the metal plate on board to clean it? Or should i change the wifi, Bluetooth, gps ic. Can someone tell me which one is the related chip ic to change? Thanks.

Hi,

Try using the phone’s WiFi as close as possible to the router to see if it works better.

If so then there is an antenna problem. The WiFi and the BT use the same antenna as they both work on the 2.4GHz band.

The phone will have to be opened and checked that the antenna has been reconnected properly.

Here’s an image taken from a teardown video of the phone that shows the antenna cable and connection in the phone.
