Hi Everyone: I recently replaced my LCD and glass screen and now my internal speaker does not work. When making calls I can hear through the external speaker (speaker phone on) or through head phones, but not through the internal speakers. I know I plugged in all three ribbons, but what could have caused this problem? Do have have to reset my phone or did I install one of the ribbons incorrectly causing the internal speaker not to work? Please let me know your input. Thank you!!
