Rear camera and speaker in Redmi 2 is not working
In my Redmi 2, rear camera is not working. If I will press in the middle and hold, then the camera is working but again if I loose, it goes. But the front camera is working perfectly.
Speaker is also not working. When any music and anything playing, it simply doing a ssssshhhhhhh sound nothing else.
The sound identifies that something is playing but sound is not coming.
Also sometimes in between, sssssshhh sound comes during charging, doing any activities.

Go to service centre .. Think You Messed up your Speaker

[N910G][VIDEO RECORDING] Clicking/Popping noise while recording videos-

Hi I've had my galaxy note N910G for about 3 months now. I have a problem when recording videos from the camera.
There is a random clicking/popping sound in the video. Initally i thought maybe I'm moving my hand too much or my finger is touching the microphone, but no....that is not the case. The pops come even when video recorded keeping the phone stationary on a table. When heard on earphones, the sound appears to come from the left side. I don't know what's wrong with my phone. Is it hardware or software fault ? What can be the solution...... anyone here who can help ?

S7 Microphone

I've seen that when I record a video, the back camera's microphone seems to focus on the right speaker and the front camera's microphone on the left speaker. Is there any way that I can fix that?

Video recording sound issues?

When recording a video using my rear camera, the sound does not come through clearly. It's as if the sound recording is focused on the front of the phone instead of the rear.
This is occurring on oreo beta 2, 3, lineage os 15.1. I've tried using the essential camera, google cam port (latest), open camera, lineage camera.
Before you ask, the microphones are clear of obstruction. There is no case on the phone. There are no microphone issues when using the phone during calls.
Anyone else experiencing this? It is making the video function on the phone all but useless to me.
Did you ever find an answer to this?

Recording issue in some apps

I have been facing strange issue while recording videos from Instagram and Snapchat.
When i record a video, The audio in recorded video gets played fine for like 1-2 seconds. But after that, sound gets muffled like something is blocking the mic from sensing impedance. However mic is not blocked.
While recording of video in Gcam or Mi Cam is just perfect as it should, So my microphone is not faulty but there are some codec issues that is culprit for muffled sound in video recording.
I have tried Dual Speaker mod to see if it helps, I tried to disable noise cancellation sensor just in case it is causing trouble but nothing helped.
I faced same issue on every ROM i flashed.
Am i the only one facing such issue?
I have exactly the same issue!!!
