I bought this phone right before UI6 update and i was having no issues at all and right after the UI6 update i started having this issue whenever i record a voice in apps such as whatsapp, telegram etc sometimes it records my voice sometimes it does not my mic doesnt have an issue since calls and recording videos has no issue of getting my voice input and phone is brand new just before update i had no issues with these apps
It is such a disappointing experience after coming back to samsung since years this basic feature issue makes me repeat myself twice maybe even third time and makes me regret coming back to it
