Såhär står det i Call Recorder - SKVALEX tråden på xda:
If you have rooted device with Magisk, install "Call Recorder - SKVALEX" from Magisk repository. It already contains everything needed.
If not, install root add-on as an apk: CallRecorderAddOn_v.2.0.8.apk md5: be5f9633ec8cf1601c88ff8b2b70488c (some features might be unavailable in this case)
If you don't have root, then you still may install Add-on to get option "start recording on answer" working, you'll need to grant READ_LOGS permission via adb in this case:
Kod:
adb shell pm grant org.skvalex.cr.root android.permission.READ_LOGS
Note, that you may need to manually enable logger in engineering menu (or anywhere else where your device manufacturer disabled it). Don't ask questions "how to enable logger" here, you better google it or ask it in forums about your specific device.
Fungerar det utan root i pie, om man inte vill spela in via högtalaren?
