If it worked fine for two weeks and you haven't dropped it or got it wet, most likely the ear speaker, shown in the picture above, is not aligned with the front camera and sensor flex cable. You should be able to get it working by re-aligning the ear speaker with the gold contact points on the flex, and make sure you put the correct screws holding down the ear speaker bracket to secure the ear speaker down properly so it doesn't move. Alternatively if it does not work, it may be possible that either the ear speaker itself, or the front camera and sensor flex wen't bad. However, these parts don't go bad "just because"
