Enable Camera Shutter Sound Switch on roooted Samsung Exynos with Android 9+
After days of searching I finally found out how to do it. The solution was to change the &quot;cscfeature.xml&quot; file in the folder corresponding to your country code. This file is encrypted, so I've written down a step by step guide. (no xposed or magisk modules needed, only root access to the filesystem):
add Call Recording en Shutter Sound options to your Exynos phone by adding 2 CSC options to cscfeature.xml


check your csc code (about phone &gt; software information &gt; service provider sw &gt; last 3 letters: [CSC])

in root explorer goto: /system/product/omc/[CSC]/conf/cscfeature.xml

download OmcTextDecoder (https://github.com/fei-ke/OmcTextDecoder)

put the downloaded &quot;omc-decoder.jar&quot; in a folder together with the encrypted &quot;cscfeature.xml&quot; file on a linux pc

open terminal and cd to the folder where you have put the files

run: java -jar omc-decoder.jar -i cscfeature.xml -o cscfeature_decoded.xml

open the &quot;cscfeature_decoded.xml&quot; file in a text editor

add the following lines to the file:
&lt;CscFeature_VoiceCall_ConfigRecording&gt;RecordingAllowed&lt;/CscFeature_VoiceCall_ConfigRecord&gt;
&lt;CscFeature_Camera_ShutterSoundMenu&gt;TRUE&lt;/CscFeature_Camera_ShutterSoundMenu&gt;

save the file and rename your old &quot;cscfeature.xml&quot; to &quot;cscfeature_encoded.xml&quot;

encode the edited file by running the following command in terminal:
java -jar omc-decoder.jar -e -i cscfeature_decoded.xml -o cscfeature.xml

copy the changed and ecoded file back to your phone: &quot;cscfeature.xml&quot; and backup the old one to &quot;cscfeature.bak&quot;

reboot and you will find the shutter switch in the camera settings!
