    Hi

    I just replaced the battery on my Samsung Galaxy S9 phone. After the battery replacement people calling me (regular phone calls) complaints about hearing an echo of their selves. I'm able to fix this by removing the back glass cover (the one that is glued on) but as soon as I put the back glass cover back people calling me hear them selves again. So I'm not sure if I have broken anything on the back cover itself when I replaced the battery or if I have broken anything related to the speaker or mic here? If I put people on speaker there is no echo, and if I use bluetooth headset everything is working fine as well.

    I'm guessing this is hardware related so the question is which hardware component I should replace here?

    Any suggestions is greatly appreciated.

    Thanks.

    You did the repair?
    The back glass comes off that easy?

    Yes, but I obviously need to use a heat gun every time I remove it.

    Hi, welcome!
    If you didn't have this issue before you took it apart then something you might of damaged , might have to take to repair center.
