Please tell us some basic information before asking for help:
Model Name: Asus 6z
Firmware Version: WW-17.1810.2009.176
Rooted or not: Not
Frequency of Occurrence: Everytime
APP Name & APP Version (If your issue relates to the app): Voice recorder, Starmaker, Smule
In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.
Mic range is too much, it takes a lots of noise as well. It can even hear sound from other rooms.
This problem is with phone's mic as well as the earphone's mic.
One more problem I am seeing is that while using any karaoke app(Smule or Starmaker), voice feedback is delayed. So it not good experience while using those apps.
