Hi everyone,
some days ago the screen of my Galaxy S7 went black while using it. If I changed the angle I was holding the phone / tapped or shook it carefully the problem went away. For 1-2 days it was reproducable quite easily.
My guess what is causing this:
I looked up where the flex connector is and how I can reach it. It is on the back of the phone, which means I have to remove the back side, which is glass glued on. So I have to heat the back and pull the glass off the body which, according to ifixit, is hard and risky. I do have an ifixit-kit and am not hesitant to give repairing my suff a shot, but I do not have much experience with delicate electronics like phones yet.
My dilemma is, if the phone is corroding and I continue using it without dealing with that problem properly, as far as I know it might end up not being repairable anymore. If it is not, I might break a perfectly fine phone while trying to repair something that is not worth the risk. Coming to my concrete questions:
Best regards
Jens

My guess what is causing this:
- Loose flex cable
- Corroded flex connector (the phone is IP68 "water resistant", but I assume over time repeated exposure to rain might reach the electronics after all)
- Broken flex cable

If it is not, I might break a perfectly fine phone while trying to repair something that is not worth the risk. Coming to my concrete questions:
- Is there any way to judge which of the assumed issues is on hand? (Without opening it up)
- Does any of you have experience with this kind of issue?
- If I go ahead an open it up, what should I prepare? e.g. look for a replacement flex-cable if available, IPA for cleaning, glue for resealing (which one/type would you recommend?), etc.
Best regards
