Back Camera and LED/Flash not working, Wifi is extremely weak.
When I open the camera app, front camera works fine but when I switch to the back camera the display goes black. In the top left corner it shows the following message, "Flash is Disabled - The iPhone needs to cool down before you can use the flash." But the phones temperature feels normal. Also the Wifi signal is very weak and it doesn't pick up all the networks around me. I need to sit right next to the router in order to pick up Wifi and connect, but even then, the signal is still very slow. I bought another 5s (with a working camera) for parts and I put the new camera and LED into my phone, but its still showing the same messages. And I also put in a new Power/Volume ribbon cable in order to fix the Wifi. I had a problem with my power button but it was fixed after that swap, but the Wifi, back Camera and LED problems still persist. At this point I'm starting to think that the problem is in the logic-board but I'm not 100% sure. Please let me know the easiest possible fix for this, whether its replacing the logic-board or replacing the components on the logic board. Thank you in advance for your answers!

have the same issue with iPhone 5s, my phone seems not having temperature issue imho. how am i supposed to fix it ? cant even open back camera, when flip to camera from front to back i get this message " iphone needs to cooldown before you can use the flash." and i cant open flashlight from control center. thank you in advance.
as I said before - for me there was a problem with loosenedn unplugged cable from the camera ! after some crashing fall or I dunno, I am used to open my phone and I know how and I just plugged it back in and it was working - no problem with iOs or so.. so better find someone who is able to repair it with tools and open the iphone, GL
