After i self repaired the screen on my IPHONE 4S..not 4, I have looked at the solutions/tips, and they were allf or iphone 4. Wifi still works, just very weak, I have to be literally 1-2 feet away from the router for 2 bars of signal. Could this be due to loss of some screws/wrong screws in different places. (wasn’t thinking of wifi/or things with the phone, was really just trying to get the screen fixed.) Now, i use 4g for “wifi” uses. Any ideas?
If it is 4s Right next to the connectors of the lcd/digitizer to right is you wifi atena covered by a metal cover check if it’s connected properly If it’s a4 it’s a different problem
