    Thank you May, for your reply.

    I agree with you that the missing phone audio is a hardware-related problem, since it worked perfectly until they replaced the charging port.

    The repair shop has asked me to return the phone to them, to open it and fix the sound problem.

    While watching a YouTube video on how to replace the charging port on my Galaxy Mega, I saw that the speaker is part of the frame, with 2 contact points that MUST touch similar contact points the mother board when you re-assemble it, or the speaker won’t function..

    I have a strong feeling that when the technician put my phone back together, she didn’t know that she needed to check that those contacts were touching each other.

    She admitted to me that she had worked on very few of the large Mega phones, which left me a little worried that she might not get it correct. It now looks like my fears were well-founded.

    Thank you for your advice, May. I will pass it on to my technician when I return the phone to her next week. – Jim Smith

    Hello May,

    I had the charging port on my Mega 6.3 professionally replaced a week ago.

    Now, while everything else works perfectly… no sound at all will come from the speaker.

    I’ve reset every software control, with no improvement. It must be a physical problem. What can be done to fix this?

    Thank you, Jim Smith

      Hi Jim, have you checked the speaker and the surroundings? I don’t think it’s a software related issue, it may caused by something broken, missing or improper installation.

    I replaced my chrging port and now I have no sound. I checked all the connections and they are all good. Please help lol



  6. BY Still, only 1 to 3 bars

    Well, I’m back. As I stated in my previous request. I replaced the charging port on my samsung mega 6.3. (see listing below. I did as May suggested and checked out the connections but it didnt make much of a difference. It will sometimes but not often reach the 4th bar. But mostly, it stays on the 1 and 2 bars and more often than not, no bars at all. What could be another problem that would be causing this please. Thanks.

    Hello. I replaced the charging port on my samsung mega 6.3. All went as it was suppose to but…after installing it I have had trouble reception. I’ve always had good bars, 4 and up but now I get the least and sometimes nothing. Also, the sound isnt as loud as it was. What did I do wrong? thanks

    • BY May

      Hello Bennie, please check if all the connectors are connected right and tightly to the motherboard esp. the signal cable on Step 9.
