I hope someone can help me with this. I replaced the headphone jack/speaker assembly on my S3 because of a dodgy headphone socket, which was pretty straightforward, but after replacement I noticed that the wi-fi reception had been severely affected, it now only works when the signal is very strong, right next to the router, whereas previously it worked pretty much anywhere. I can also now rarely get adequate reception at public wi-fi hotspots. I thought the problem might be with the new assembly so I reverted to the original one but it made no difference. I know the wi-fi aerial connection is in the same vicinity but I have checked and it all looks OK and nothing appears to be damaged. Does anyone have any suggestions or experienced anything similar. Do I need a new wi-fi aerial?
