There might be, depending on how bad your damage is, that you might have damaged the connectors on the logicboard? havent really had any chances to look inside the new Iphone 7, but i would think the connector is probably damaged, or something? :) Good luck, hope i was for some help :)

This silver ring follows your docking/charge port, its an solid part, witch cant be taken off, or switched in anyway, other than painting it, this is a part of the connector, i'm sorry for my English, it ain't my first language.

i would think, even though that it seems dry and look dry, it might be a little waterdamage? cause it was there for 3hours as you say, You could try to extract pictures through your computer and phone, in my little quick tutorial(just click tutorial to get to it) but i cant promise it will work as if it is wateredamage in the phone the memory might be fried, but you could try if you have take the SD card if used? and see if there might be photos on that? my phones usually store all my photos and apps at my SD card Good luck mate! im sorry if i was to no help, but worth the try!

You ain't giving any information as if might have dropped it one time or so, but my opinion is that this screen obviously lost its connection to the camera? it might come from that there is an contact inside the camera that can have fallen out, or just simply the screen is broken, but you could send it in to gopro or someone tech repair shop related to have a look at it? Good luck mate :)

Hello Nick! i can help you with the wifi, what is most likely happened is that the wifi anetenna had a big shock of the fall, and might been "jumped" out of it socket, but i have only experiensed this at Iphone 4/4s. for the wifi antenna see HERE & HERE i would've changed both the antenna it self, and the cable just to be on the safe side, aswell these are quite cheap products :) but maybe for the battery you could buy a new one to help it HERE Im sorry if i was to no help, but good luck buddy! :) Happy fixing ;)

Hello James! I would guess, but not entirely sure, but there should maybe be this screw underneath your computer? Hopefully it was to little help :) good luck!

Have you taken your computer apart one time or another? if so it might be the connector underneath your keyboard that connect to the computer's motherboard that either is loose or bad connection :) Good luck! hope it works out!

Hey bob! I just made this Guide just for you now! Hope you understand and it wasnt to hard to perform! :) Have a great one!

Your screen is a "packet" with many layers of tech, haha easy explained, the crack might be tiny, but if it is deep enough it will damage the digitizer or lcd, or just simply the whole thing, but as you refer for, is the touch defective. it is kinda self explaining i would think this answer? I am sorry if this is a bad answer or really bad written but it is the best i could write in english, haha sorry. Here is a little picture of how touch screen works:

I would think if something is loose? It would be, harddrive,memory(ram),fan,bios battery and such? It wouldnt hurt to take a quick look, but just be careful and dont break it more? Do it, do and learn is what I say, unless its a customer, or your job, haha :) And i am sorry to hear about your accident! Hope it ends well till the end :)
