After dropping my iPhone 7 it has kept rebooting with the wifi and bluetooth working, but as time went on the wifi began to become to be greyed out- even though a wifi dress can be seen in General> About. later on after watching some videos i have found that the problem is internal and to do with some IC units being damaged or the solder being cracked. If there is a part to replace could anybody send me a link to how to replace it etc.
This is one of those “if you have to ask, you can’t do it” kind of repair. Send it in, don’t do it yourself.
