Flash, Mute and volume buttons intermittently stop working.

Hi all!

After my recent mishaps with a MacBook Pro I've decided to try and fix another thing, my SE. I got the phone around half a year ago with a broken screen, faulty flash and mute switch.

I then went about replacing the whole housing and sceeen with an iCloud locked phone and all was well until around 2 months ago. Every few days, if the phone is *vigorously* placed on a desk or handled too hard, either the flash, mute switch, or volume buttons or even the vibrate motor will totally stop working.

After taking the phone apart, disconnecting the cable and connecting it again it works fine, but I can't continue doing that as I'll eventually mash up the connectors and strip the screws.

Does anyone know of a permenant solution to get it working again? No soldering though as I can't do that sort of thing at all! I have tried cleaning the connector with surgical spirit to no avail.

I would take a very close look at the Upper Component Flex. Even a tiny tear could be enough to cause issues and they would invariably occur when handled in a more physical manner. These flexes can be very delicate and it's not at all uncommon for them to be damaged when they are replaced.

The linked guide os for the iPhone 5S but it is the same thing as the SE (which has no guide).

When I replaced the logic boards I didn't transfer the cable. What are the odds of having two faulty ones?


Forgot to add, both the connector and the cable appear to be in good condition at first glance


The only common denominator between all of those functions is the Flex and the connector. So if you are confident that the Flex is okay, take a close look at the actual connector on the logic board. Beyond that, this will have to be looked at by a micro-solderer.
