After water damage I couldn't make calls, WI-FI worked OK, but I first get only 2 bars in signal icon and after that all bars shows up but I still couldn't make any calls. Call screen frizzes when I try to hang up (no voice on the speaker too). When someone try to call me it give him ring signal but my iPhone didn't show anything. When I try to call someone his phone rings but he couldn't hear me (neither do I).
I solve the problem using contact spray (DRY OIL-FREE CLEANING SPRAY; PRF 6-68) on the antenna screw and antenna connector and also on the ""blue signal coil"".
I let it dries and assembly my phone. After this operation everything works fine.
THANK YOU for your help Simon and Craig !!! I hope this will help anyone who has similar problems."
"This would totally make sense. I have cleaned my iPhone 5s board with my ultrasonic cleaner fitted and new screen and battery. Working fine for a good 10 days then i lost signal always searching for a signal. Time for me to dissemble the phone again and replace the screws.
Hi I am having the exact same problem on my Iphone 5s and really need some help, I have never opened up my Iphone before and would love some guidance, I experienced water damage and replaced my dock connector and now am having this no service issue on my phone, same as you did. Could you walk my through how you fixed it? Thank you so much
