Hello SJCAM, Currently I have 2 SJ8s adopting FW v1.2.0 which was recently released. But I have trouble to hear recorded sound from both devices. Please check below 3 videos. They are recorded in normal speaker settings and no change done during the test. Firstly please set the speaker/Windows/application volume like you can hear Galaxy S3 as normal. - Compared to the sound captured by Galaxy S3, both SJ8 show extremly low sound. - Comparing 2 SJ8s, one(SJ8 new) shows noticably lower sound. Seeing SJ7 manual,there is menu for mic volume as follows. But SJ8 doesn't have it. >> MICROPHONE VOLUME › Sets the sensitivity of the microphone. Regardless of the menu existence, I think this kind of setting has default value in NVM and it is written during falshing the device. I mean normally it can't be a random value. Hence I suspect this too lower recorded sound as a HW(mic) issue. Please check this issue and get back. [Samsung Galaxy S3 Normal Volume] [SJ8 old Normal Volume] [SJ8 new Normal Volume] Thanks. P.S. Please let me know if you can't access Youtube. So that I can send the files to you.
