    Its been 3 months when I got a replaced Lumia 930 from the service center. Now I have started 2 major issues.

    1) Microphone Issue: In the call when I set in speaker mode, the other person is unable to hear anything. His voice is loud and clear. However this issue isn't there when the call is in normal mode. Earlier it was so good that even if I place the device more than 3 feed away, the other person was able to hear me. But now even when I bring it near my mouth, the other person is unable to hear anything.

    2) Battery Drain: There are 3 occasions when I found that battery was more than 50% charged in the night, but next day the device was off because the battery was completely drained. It doesn't show in battery saver that which application suddenly drained the batter. Could it be because of CPU overheating issue?

    If anyone in this forum has faced a similar issue, can you tell me a solution to this?

    music detection SW (like shazaam etc) and calling on loudspeaker - if thats fail, try in test mode in Nokia Care Suite - theres 4 mics can be testet separetly. On my L930 Mic 3 and 4 is not working, so i send it to RMA.

    Its HW defect a only solution is microphone get replaced.

    Download NCS 5.4.119.1432 (LINK) + UserGroupsConfiguration.cfg (LINK)

    Copy that .cfg to install folder (C:\Program Files (x86)\Nokia\Nokia Care Suite\Product Support Tool For Store 5)

    Launch product support tool - connect phone - it will be recognized, then on left panel says Normal Mode - switch it to TestMode.
    Then you can test whatever you want. After that switch it back to normal mode.

    I scare too to give my phone to the care. (Heard a lot of bad stories about them in my country) But I have to. And maybe I'll tell them that my phone's battery is draining fast, and the speaker is making that little noise sometimes. But I want to ask for a help from you guys: my backup processing always giving me an error before the finis (usually at 97-98%). If I give it to the care, they are not going to make a backup, what should I do?
    Thank you for your replies!

    Even I have the same problem. Recently found that when I put the phone on speaker, the mic doesn't work (i.e other person could not hear my voice) but it works fine in normal mode. I think this is a software issue. Not sure whether this gets fixed in Win 10.

    There are two hardware design issues with Lumia 930.

    1. The two mics on the rear fail after sometime due to grounding/shorting issue. Even after mic replacement it fails after sometime.
    2. The screen flickering on 2G / EDGE connection again is a design issue due to improper shielding of 2G Radio.

    Nothing can be done about these issues, just learn to live with them.
