Hi everyone! I have been several weeks with a problem in the earpiece. Its volume is very low, I almost can't hear in call through the earpiece. However I can hear without problems if I use headsets or bottom speaker. This problem appeared suddenly, after almost 1 year using it without problems. I have tried reset the iPhone, restore from the iTunes. I've try to adjust values on Celestial.framework .plist files, even I've tried Volume Boost software. I've replace the earpiece and cable #3 (induction line) for a new ones, and the volume continues being low. Conclusion: I'm at the start point. At this point I'm desperate and I would be very grateful if someone could help. Thank you!
