Weak or no mobile network connection after water bath


After I accidentally dropped my S2 for ~1-2 seconds in water, I could fix problems like the not working Usb port and power button with a soldering bolt and a new usb socket. The system itself runs fine.

The last problem I face is that I have flawed connection to my carrier. I have maximum 1-2 bars of connection, but also recurring connection losses. As a result phone calls are impossible to do in short time.

What can I do to fix the antenna?

Best regards

I ordered a new antenna via amazon for 10 bucks. I hope this helps.



The new antenna fixes the problem. It seems that not the old usb socket, but the antenna caused the usb connection problems. With the new usb socket I got the weak mobile connection. Now i replaced the new usb socket with the old and the old antenna with the new. Now everything seems to work fine.


hi i have the same problem,but my phone was not dropped in water.

Glad to see that your phone works again. Fortunately, water accidents can be fixed another way. Some shops can try to take a deoxidizer bath to your phone. This worked in my family with an iPhone incidentally dropped in water and no longer detecting any WiFi network or SIM card
