If you hear a screeching sound instead of the spoken words: ‘Rotate the aircraft…’ then you might have to disable Speech Services.

A strange sound when recording video

Hi, I am using Litchi v4.26_BETA-g Build 30004382 with Mavic 2 pro and Samsung S7edge (SM-G935F) with Android 8.0.0. Since a week or 2, when recording video, or switching photo to video (or reverse), I get a strange sound during about 10 sec This sound disappear if I set sound to very LOW on the smartphone, or if I set voice OFF in the settings of Litchi app. Besides, nothing like this happens with DGI GO 4. Does anyone get such trouble ? Thanks for your return
