Chosen Solution
My iPhone 6s had a third-party screen replacement in August. After the screen was replaced, they did not put the two pentalobe screws back in the bottom. A couple months ago my home button became unresponsive. Today after my phone fell about two feet, my screen came off (attached still by flex cable so it still works). Now, my charging port, headphone jack, and bottom speaker no longer work. The flex cables are not torn. From what I understand from other sources is that these cables need the appropriate pressure on them in order to properly respond. If I apply pressure on the bottom right portion of the main display (not glass), my headphone jack works. If I apply pressure to the bottom right corner of the glass, my home button and charging port work. I haven’t been able to get the speaker to work at all though. The phone also no longer vibrates. Do you believe this problem would be solved by putting in the two bottom pentalobe screws, or do you think there is more internal, not-obvious damage to the phone ? Would replacing the charging port/headphone flex cable fix the speaker and vibration problem? Thank you in advance.
@mirandajesse you got a lot going on there. No, replacing the two screws is not going to fix it. Start by replacing the lightning connector and then re-evaluate. iPhone 6s Lightning Connector Assembly Replacement The home button may not be working due to the screen coming out and possibly tearing the flex. Consider replacing that through Apple to maintain your Touch ID finger print scanner. iPhone 6s Home Button Assembly Replacement
There is more internal problem with your device. The phone should work fine without the pentalobe screws.
