Microphone doesn't work on a start of a phone call Galaxy J3

[user7VJR8KTf2b]

When I answer or make a phone call, people can't hear what I'm saying. Its like the microphone is off. If I turn on and off the speakerphone then the regular microphone will work fine.. It only does it at the start of a phone call. Please help

You can only speak aloud because I think the background noise filtering algorithm of the phone is faulty and if the speech volume is low, the speech can be filtered out of the microphone sound. Conclusion: The design of the samsung j3 2016 model is faulty.

Solution--- grab a sewing needle and there are 3 holes on the bottom of the phone, 1 is charging 2 is headphone jack, 3 LITTLE hole that is the microphone, insert the needle there and drag it back along the sides to clear the whole of microscopic debri from the hole that is blocking the sound to get to the mic.

I have the Samsung J3. Its only 2 years old. I just got service hooked up on it and the phone was working fine when I made calls but then it stopped working. When I call people, I can hear them, but they can't hear me. I tried doing the speakerphone thing, but it doesnt help. I just got the phone.

@userKZsDeCAnHF: Just to confirm, was your device purchased in the US? 

[userKZsDeCAnHF]

No, in the UK. Is this just US? I was just searching for people having the same difficulties as me and I came across this thread.
