I’ve had this tablet since September 2019 and today it started doing this: Whenever I record something on camera the audio of the video sounds muffled, but if I watch YouTube the audio of the YouTubers dont sound muffled. My camera audio was perfectly fine until today. Please help.
Try cleaning the microphone holes with a brush or by poking it with a fine tool carefully only need to poke if it visually looks like it is blocked with gunk. There is one located at the top and other at the bottom. Sometimes there is one on the side too.
