Microphone in Nokia Lumia 510 is soldered to the motherboard of the mobile phone. So there is a very little chance it gets damaged or disturbed. If by any chance it does I have marked all the Mic Ways Jumpers points in the diagram below.
Now remember before making any of these jumpers please make sure that a faulty microphone is not causing this problem. Only make these jumpers if the microphone’s placing prints are damaged. Second thing you don’t need to make all the jumpers as shown here. I have marked all the ways just in case you have damaged the next points too.
Please Note that we will edit these solutions or add new ones if found in this page at any time in the future. So feel free to come back any time on this page to stay up to date.
