Microphone issue

[Aateri]

A few month ago i purchased this galaxy tab a11+.first problem i faced some problem ,i reach out the service centre and they solved that. Few days later .Samsung software updates are there .so i installed it .but from before that i try to use the voice search feature.and facing isuue only when using google,chrome, and youtube. I tried everything i can ,but the issued temporarily fixed up for 24 -72 h max and then same problem again. Like if i update play servieces or web view from settings ,or restart the tab it fixed temporairly and same problem came agin. Few days back i faced the same issue during call,specifically ist call and anyone could not hear my voice.cut thecall and call agin the. Mic is working temporarily in all earlier mentioned apps.chcekd on samsung diagonistics found there is isuue in both the mic,so go to voice recorder.prperly recorded my voice and chcked again ,found there is no issue in the mic. In wp or other apps it works fine. I got an update for ui 8.5 ,i updated as i thought may be the problem will be fixed but again today gind the same problem. I am a student ,for me its a great loss as i invested a great amount for buying this .does anybody has faced the problem like me ? Whats the solution?
