When im in the phone trough Dudu7 ppl complane about a terrible noice like im using a grinder while talking. Its the internal fan that makes this noice but why? Outside its not that bad... Where is the mic used? I hold my finger over the MIC and RST holes but sound from me dont change. Is there a mic on the back?
Dudu7 microphone and fan noice
Unfortunately the Mic quality on all FYT devices is poor, DUDU7 has an improved setup to the majority utilising both the mic next to the rst button and an external mic.
If you have bought the DUDU7, you should have had an external mic included that looks similar to this
Unfortunately the placement of the external is critical, make sure it’s close to the direction for speech and away from noisy areas as it can pick up noise from the engine/aircon etc
I had this problem and tried the external mic supplied with my Dudu7. Its garbage - cheapest of the cheap.
Following advice from YouTube I purchased an Olympus ME52 mic from Amazon. Not cheap, but way better sound quality.
