Chosen Solution
The loud speaker stopped working , I changed the piece out & it still does not work. A day later the vibration & headphone jack is not working ? But the charging is working. Could it be that the cable is not plugged in correctly or maybe I should replace the whole charging/headphone jack flex ? How can I fix this ?
It’s, yeah..you need a new Lightning dock iPhone 6s Lightning Connector Assembly Replacement iPhone 6s Lightning Connector and Headphone Jack
replace the charge port that should fix the issue
Need to ensure if the speaker pins sits without disturbance on the copper pad of the charging /lightning connector assembly itself. This correction also solved issue of vibrator which was not working.
