iPhone 6 front camera recording videos without sound
Hi, guys.
I have an iPhone 6 for more than a year now and I'm recently facing problems while recording videos with the camera app. All the videos that I recorded yesterday at a concert with the back camera had no sound at all. Then, I made a few more tests after restarting it and it seemed normal again. But then I tried the front camera just to be sure and I got no sound again.
I just installed iOS 10.3 using iTunes to see if it came back to normal, but it still doesn't work. The audio from the back camera seems fine now, but the front one doesn't work.
The weird thing is that both cameras work perfectly fine on other apps like FaceTime, WhatsApp, Messenger, Instagram and Snapchat. I can hear music/audio on YouTube, Facebook and Soundcloud just fine. I tried installing a recording app to see if it worked as well (VideoCam - the first one on AppStore) and there was sound only when I recored the video with the back camera. Static sound with the front one.
I already seached for possible solutions and found nothing. I don't think there's anything blocking the microphone/speakers on the front or on the back, the volume is all up and it's not on silence mode. Nothing happened to my phone in the past few months (it didn't fell or anything like that).
Don't know what to do. Has anyone else faced the same issue? Please.
Thank you very much and sorry for any misspelling.
iPhone 6, iOS 10.3
