    Hi, my S4 mini started producing loud crackling noises instead of playing music/sounds. The weird thing is that they don't appear always. E.g. when I reboot the phone the start-up music plays fine (most often) and the sounds works for a minute or two, e.g. the bing-sound when changing the volume. But then, without warning, suddenly only loud crackling noise comes from the internal speaker. Every now and then it goes away for a few seconds and works normal again, but then it returns to this terrible crackling noise.

    I have already done a hard reset, which hasn't changed anything. SIM card and SD card are removed and the problem is still there.
    What can I do?

    Welcome to Android Central! Try booting into Safe Mode, which temporarily disables all 3rd party apps. https://support.t-mobile.com/docs/DOC-27781

    If the problem disappears in Safe Mode, then something you installed is causing the problem. You may have to uninstall apps one by one until the problem disappears. If the problem persists in Safe Mode, then it's more likely to be a hardware or firmware problem.

    The problem is still there in Safe Mode. I guess I'll have to return it... bugger.

    You could also try reinstalling the firmware using either Samsung Kies (http://forums.androidcentral.com/amb...sung-kies.html) or Odin (http://forums.androidcentral.com/amb...interface.html). But if you have the ability to return or exchange it, that's probably easiest.

    Would this somehow impact the warranty (reinstalling the firmware)?

    I can get the phone exchanged but this would take time and be somewhat complicated.

    I'm not sure, but since you don't have to root the phone, I think the warranty will still be valid. This thread might help: https://www.reddit.com/r/GalaxyS3/co..._through_odin/

    Lol, Kies comes immediately back with "GT-I9195 does not support initializing".

    Well, then I'll return it.

    One other thing to try is Smart Switch: SmartSwitch: Install & update or replace firmware. (I'm never quite sure which devices are compatible with Kies and which ones are compatible with Smart Switch.)
