I replaced my iphone 5s screen with a new one that contained all the parts, all I had to do was plug in the 3 cables. Well, now the ear speaker doesn't work. I thought I got a bad iphone 5s lcd replacement so I ordered another from a different company. I just installed it and the ear speaker still doesn't work. I also tried plugging and unplugging my earphones to clean the earphone jack. What next??
Answer:The ear speaker is one small separate part inside the iPhone 5s that doesn't interact with your headphone jack in any way. Normally, the ear speaker is held in place by 2 small screws. These screws tend to come loose during shipping. Tighten the 2 screws over this part (located at the top of your device under a squarish metal shield), and everything should be fine.
If this does not work, then your top speaker may be loosing it's magnetism during shipping. Have 1 of those companies send you just the ear speaker, and swap the apple replacement parts. This should fix the issue.
If neither of these options work, then it is possible that your device's ear speaker circuit was blown out. If this is the case, no ear speaker will work at all. The good news is, you can always you a headset with a mic or speaker phone mode to take calls.
