Actually I feel almost any component in general sadly. I had to replace the front camera assembly as well and after trying almost four different parts from multiple vendors and none match the quality of the original.

Another thing I learned is that Apple would replace the entire display and front assembly (front camera, earpiece, speaker, brightness sensor, proximity sensor) for only ~ $150. However, due to the third party battery they couldn’t work on it anymore.

I had bad luck with original Apple batteries and got a good third party battery, so your milage may vary.
