  • Ok, thank you for your help. Yes I will think about it and come to you back if I have to the soldering or not.

  • Hello, I have a problem with the mic on my GT-N7100 and the “Capacitor-2” is not on the motherboard. Can you tel me where I can find the replacement one?

    • there are a lot of stores from where you can find the capacitor. Simply order it online.

      • I have search a lot and I don’t found the capacitor. Is there any references on it?

        • You can see the last image, all the capacitors are marked in last image. If you are still having problems then take picture of your board and send me, i’ll point them out for you.

          • I finally found the capacitor 2 with the Note 2 Schematic and Electrical part list. Sec Code is : 1203-004819 for the capacitor which I don’t have.

            On last thing, did you know how I can solder it on the motherboard?

            • That’s great! Well you can solder that on your motherboard with the help of a soldering gun. But i recommend that you should have some soldering experience before you plan to that.

    I’m having mic problems with my s2. I ordered a new mic for it and had a guy replace it for me, but problem is still there. I’ve updated the phone, problem’s still there. I’ve also poked it with a pin, still no joy! But when I use the voice recorder, my voice is a little low. But it does work. . Getting frustrated with it now, please help! If possible! Thanks.

    • Terri all you have to do is to replace MIC rubber cap. This problem occurs when your Mic rubber is displaced or it is out of order.

  • Hi, I liked your input. Was fixin’ to get out my soldering iron. Tried the needle. I used earbuds /mic yesterday. Very mad! Well, yesterday, I saw a volume bar after hanging up with someone. It appeared for 1 second. Saw it again last night and turned it up and pesto, it worked. Just wanted to get that word out. Calling Verizon today and going to the top. Thanx for being here!

    • Thanks for your Feedback, I guess the problem was due to some minor glitch. And You are welcome. Glad to help our readers! Best Regards.
