The 3G 8gigger shows ringer on the screen,,so headphone jack i dont think is the problem,,I am still unable to hear through earpiece,unless using speakerphone,,blah blah,,have done the qtip/plugging/unplugging,etc nothing works,,but here is where it gets bizarre
when i dial out the phone call,,im using the speakerphone icon at present,,due to the earpiece problem,,but what I can not figure out,,is ABOVE the dialer keypad,,im just talking with a friend,,all of a sudden a beep,,then another beep,,i remove the phone from my ear,,and the beeps corresponding number on the keypad,,or whatever sound is designated when you push a certain number on the pad,,Anyways I talked for about 45 seconds,,told buddy i would call him back later
here is what dialer looked like
3233832883,,so the beeps i heard while talking were being entered above the dialer
That would be a faulty camera, or the cable to the camera being loose as it can be disconnected from the mainboard. Last phone I worked on with that issue, the camera was bad for some reason....replaced the camera (cheap on ebay) and it worked fine.
A drop can damage the camera if the phone hits right.
