Kindly Remind

Warning 1.  It’s weird design that there is no any supporting shield between earpiece speaker and touch panel, which means the earpiece speaker is stuck on Sony Xperia Z3 front glass directly. So if you handle properly when remove screen, the earpiece speaker will come with the screen together while if not lucky, the earpiece speaker will be separated from screen like what we have done (but it’s dangerous and easy to break earpiece speaker).

Warning 2. What the black bracket you are seeing is for securing earpiece speaker by kinds of adhesive sticker. So the “proper handle” reminded above is never let your guitar pick overpass that bracket when cut the sticker. Remember it’s position and the guitar pick length you use.

Warning 3.  Sad news – the new LCD screen doesn’t come with the bracket, which means you have to remove the whole earpiece speaker with the bracket into the new screen rightly. it’s difficult and really complicated. But if you have any good idea about this, please leave your comments and let us have a lesson.

Why Sony Xperia Z3 not waterproof after LCD screen replacement

Reason 1. If you get the original LCD supporting frame sticker and back cover sticker. They do a lot on waterproof.
Reason 2. You can see that the removed broken LCD screen comes with the waterproof tape to cover the earpiece slot but the new LCD screen have no. So when you choose the LCD screen, you should pay attention to these small but important points.

Reason 3. The MIC also means a lot. The MIC of Sony Xperia Z3 is covered by a kind of rubber film. And when you pry it up, you maybe have broken it. That’s the second risk.

    hey, thanks for post this article that let me know structure of xperia z3.
    in fact, I have one question, and it bother me a lot.

    I have bought a xperia z3.
    and one time, I try to use a pin to clean up the hole of loudspeaker,
    and it’s broken a little hole.
    I think the waterproof tape is a little broken.

    and I try to clean it after,
    I think it still waterproof because after soak it into water
    it still work,
    but I’m not really sure.

    I send it back to xperia care
    and they told me it need $159
    it’s too expensive.

    so… can you give me a suggestion if I have to change it or not?

    BTW, there is a waterproof front housing sticker on lcd
    why it still need waterproof tape on speaker hole?

    I think if it can waterproof in some life case,
    like use in rainy, clean lcd screen with water,
    use in bath, I will not change it.

    thanks!
