I have a Google Pixel 6a (bluejay) phone. On this phone camera makes shutter sound when I take a photo. I have looked up the phone by IMEI by going to https://store.google.com/us/device-authenticity?id=[IMEI] URL and it shows "Intended region: IN,JP". I have previously installed LineageOS and rooted it to remove the files /product/media/audio/ui/camera_click.ogg /product/media/audio/ui/camera_focus.ogg, /product/media/audio/ui/VideoStop.ogg and /product/media/audio/ui/VideoRecord.ogg. This removed the sound, but because of the root banking applications complained, so I reinstalled the system to CalyxOS without wiping. Now I want to remove the same .ogg files without rooting the phone. I have downloaded https://release.calyxinstitute.org/bluejay-factory-25608200.zip file linked from the page https://calyxos.org/install/devices/bluejay/linux/ . It is an archive with all partition images. Inside an archive there is another archive bluejay-bp1a.250505.005/image-bluejay-bp1a.250505.005.zip which I unpacked. This archive in turn contains product.img file. I unpacked product.img by running unzip image-bluejay-bp1a.250505.005.zip product.img. I confirmed that product.img contains the files media/audio/ui/camera_click.ogg and similar. I tried to mount the image and got this error:

# mount -o loop product.img /mnt/
mount: /mnt: wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error.
       dmesg(1) may have more information after failed mount system call.
# dmesg | tail -1
[360861.911279] EXT4-fs (loop0): couldn't mount RDWR because of unsupported optional features (4000)

I ran e2fsck -E unshare_blocks product.img and then tried to mount again: Then the image mounted successfully with mount -o loop product.img /mnt/. I then modified the image:

cd /mnt/media/audio/ui
mv camera_click.ogg camera_click.bak.ogg
mv camera_focus.ogg camera_focus.bak.ogg
mv VideoStop.ogg VideoStop.bak.ogg
mv VideoRecord.ogg VideoRecord.bak.ogg
cd /
umount /mnt

Then I rebooted the phone to fastboot with adb reboot fastboot and flashed the modified product.img to both slots:

# fastboot flash --slot=all product product.img

However, after rebooting the phone, the camera still clicks. The files are also still there:

$ adb shell
bluejay:/ $ ls /product/media/audio/ui/camera_click.ogg
/product/media/audio/ui/camera_click.ogg

/system/product is a symlink to /product. Why the files were not modified? How can I still remove these files?

The stock camera app on my Moto G62 5G has a "shutter" sound that is played when I start OR stop recording. The problem is that I'm vision impaired and I'm never sure whether I have just began shooting a video or have just stopped shooting it. It would be great if I knew a way to play 2 different sounds in the two cases. Any ideas? I used to use an alternative cam app called HedgeCam 2 which does this. But unfortunately this app has recently become buggy on my device.

How to turn off shutter sound on LG G5 with latest official firmware (Android 7)? "Do not disturb" sound mode does not working for shutter sound.

This question has been asked a lot of times, but since new versions of Android rolling out the given answers are not accurate any more. The old solution as root was to rename the *.ogg sound files in the **system/media/audio/ui** folder but since Android 9 the sounds are **hardcoded into the Camera App**. On devices in countries where it is forbidden by law to take sneaky pictures (Europe for example) Samsung had to remove the **switch** from the options where you can **disable the Camera Shutter Sound**. My question is: **how to put back the switch into the Camera App options menu**?

This question is basically the same as [this one](https://android.stackexchange.com/questions/89/how-do-i-disable-the-click-sound-on-the-camera-app) but the canonical answer for that post is not compatible with my particular device for which a discussion and a solution can be found below. I would often like to use the [Samsung Galaxy SIII Neo](http://www.gsmarena.com/samsung_i9300i_galaxy_s3_neo-6289.php) stock Camera app but would like to keep the sound it makes while pictures are shot on silent (so that when I take a shot people are not distracted by the sound so that the resulting pictures taken look more natural). However, I've figured out that to turn such sound off, out of the volume settings Ringtone, Notifications, Media, and System, it is the Ringtone volume setting which must be turned off for this to take place (click on any of the volume hardware buttons and then on the volume settings cogwheel to see these). Unfortunately, setting the Ringtone to silent means no sound will be made when a phone call is received. So, I would like to know whether newer phones have a Camera setting menu list entry for enabling or disabling the sound specifically for the Camera application. And, if not, then I would like to know where to place a feature request width Samsung for this to be implemented in future releases of the stock Camera software. Anyways, I think, as a hack, if one knew where the mp3 sound file for the camera app is stored, one could just deleted (or perhaps replaced it with an mp3 file producing no sound to resolve the problem). Anyone know where I could find such a file? --- **UPDATE**: I've tried [rooting my device](https://android.stackexchange.com/questions/102430/what-are-the-advantages-of-enabling-or-disabling-samsung-knox) and then following [this solution](https://android.stackexchange.com/questions/89/how-do-i-disable-the-click-sound-on-the-camera-app) but I still get an error message saying the filesystem is read-only. Not sure if [Samsung KNOX](https://android.stackexchange.com/questions/102430/what-are-the-advantages-of-enabling-or-disabling-samsung-knox) is causing this. Thank you for your replies. --- **UPDATE**: Remounting the system with the following command as root: mount -o remount,rw /system Allowed me to rename the file, but it seems it's the wrong file as the stock Camera app still produces a snap sound when taking a picture after the rename. Candidate files related to the stock Camera app under /system/media/audio/ui could be the following: - Cam_Start.ogg - Cam_Stop.ogg - Camera_click_short.ogg - Camera_click.ogg - Camera_empty.ogg - camera_focus.ogg - Camera_Timer_2sec.ogg - Camera_Timer.ogg I've tried renaming both Camera_click.ogg and Camera_click_short.ogg to Camera_click.ogg.bak and Camera_click_short.ogg.bak but no luck! Even after rebooting the phone, the stock Camera application still produces a sound when a picture is taken with the Ringtone Volume enabled. The Camera_empty.ogg sound file produces no sound; ideally I would like this one to play when the camera takes a picture. Anyone know where the problem may be and how to fix it? --- UPDATE: After installing the BusyBox app in order to have the Unix find tool and then running: find / -name '*.ogg' > out.txt the contents

Notification.ogg At this stage I'm not sure whether the stock Camera app is really taking the shutter sound from one of these .ogg files or whether the actual .ogg file is hardcoded into the stock Camera app's binary file.

I have tried many android application to record voice, but they're quality is not great, often it muffles the sound, as a result of forced noise removal. But surprisingly, the video recorded from the stock camera records much much high quality sound(no distortion). So is there is anyway to utilize this fact? The device is a Asus Zenfone Max pro M1 (ZB601KL-4H070IN). Android Version: 8.1.0

Where is located the **camera shutter sound file** on *LG G2 mini* (Android 4.4.2)? Or how else to **turn** that annoying sound **off**? ***None** of the solutions recommended in similar questions here does work. The phone looks like requiring its own solution.* The accepted answer for https://android.stackexchange.com/q/89/68373 recommends deleting /system/media/audio/ui/camera_click.ogg. I deleted the file, rebooted the phone several times, however the camera did not stop making the shutter noise. N.B.: My phone *is* rooted. I want either to delete the file or replace it with an no-sound file, however the location given in the related question does not seem to work on LG G2 mini. The solution with setting ro.camera.sound.forced=0 in build.prop does **not** work either. Explanation to avoid some off-topic answers: 1. LG G2 mini native camera application has 4 predefined shutter sounds, with no "None" option. 1. I don't consider switching the phone on *silent* as a solution. 1. I am not asking *why* LG does not have the option (whether it is somewhere legal or not), but *how* to turn the sound off. 1. My phone is rooted so I can change system files. I just haven't found *which* files should be changed and *how*. 1. The problem might be deeper. As the description of the Camera Sounds Off! application says: > Don't work on some devices by ... > > *LG (The LG's camera app has own not removable sound files!) Actually, I don't believe in anything *really* "not removable" :), but removing them probably will require some trick which I have not found.

I have a Huawei G525 (Android 4.2 jelly bean). The Camera makes a sound when taking photos even when it's in silent mode. How do I disable the shutter sound altogether?
