I just did a screen replacement on an iPhone 6 and because the front camera was also very foggy I replaced it too. I noticed that when I’m talking to Siri the screen turns off, the phone vibrates a little bit and I can hear Siri talking but very very quiet. What could the problem be?
Hi, Possibly a proximity sensor issue. The replacement front cam you received may have a faulty proximity sensor, or you may have placed it in incorrectly. As for the speaker, that also may be damaged, or it could be placed in the ear mesh gasket incorrectly, or some adhesive may be in the way, blocking the sound. :-)
