Chosen Solution
IBought the phone 6 in end of April, by End of June, Siri and voice to text stopped working. Apple Store replaced the phone, worked fine for another month, same problem. Apple Store replaced the phone AGAIN in July, worked fine until one month later (August) Apple Store replaced the display this time. Worked fine for another month and now (Septmber) crapped out again!!! I am frustrated to say the least. I have had 3 new phones, and one new display in 5 months!! I take care of my phone to the point of being OCD about it, I use the OtterBox Defender case ALWAYS!! And I clean it constantly. Only thing I can think of is that I use it in my car for music plugging into auxiliary through the headphone jack, so maybe the headphone jack thinks there is still something plugged into it even when there isn’t, because this last time, it wouldn’t work even with the headphones plugged in until I wiggled the jack a bit, and then it worked, but still only with headphones. But now there is no voice feedback or tone from Sirir when doing this. Frustrating as !&&*, any insight would be welcomed!!
A good way to know if your device thinks headphones are plugged in or not is by pressing the volume up and down buttons. If RINGER shows on the screen then the device does not think headphones are plugged in. If HEADPHONES shows on the screen then yes the device thinks something is plugged in. Are you using any kind of liquid solution when you clean the screen? Siri microphone is at the top of the screen next to your earpiece speaker, so if you’re using some kind of liquid or spray it could be getting into the microphone and causing it not to work anymore. On another note, if you have to to wiggle the headphone jack to get audio to work you need to go to apple for another replacement before your warranty runs out. After, maybe get a new auxiliary cable, if you’re using a cheap low grade auxiliary cable it could be shorting something out in the device.
