New Earpiece Ear Speaker flex cable headset flex cable For iPhone X~12（without earpiece） Item NO.: 1446912

Which kind suitable for you?
1, the earpiece problem
You can change the earpiece alone, and the process requires welding, and the face function will not be lost; you can also change the assembly but the face function will be lost. If you want to keep the face function, you must move the face IC of the original machine to the new line.
2, the problem of no sound when talking with light sensor or when the speaker is turned on
This kind of assembly can only be replaced, and the functions are all online, but please note that if you change directly, the face function will be lost. If you want to keep the face function, you have to move the IC on the original machine to the new cable. 
3. Face function broken
This has no solution, unless you can determine that the IC is good, and the bad is due to the line body problem, then you can use the cable assembly to move the original face IC over.
