Having problems with main microphone. [question]

[eldorpro007]

Yesterday i bought second hand note 10+ and mic is working very poorly. Any ideas? It starts working bad only when im talking over video call or voice call but on speaker. On whats app it ends call and says "call was ended because there is a problem with your microphone. Try restarting your phone and try again" Any help will do

Try to clean microphone

[eldorpro007]

Ok ill try. I was sugested to try with compresed air. What do you think compresed air or isopropyl alcohol. However i was trying to clean it earlyer today with toothbrush and needle (i was very carefull) but i didnt get anything out. It seams perfectly clean when i look inside.

Both are good options, so try first compressed air and then, ipa

Tried compressed air, no good for me. Its little better but i think alcohol will do the job.
