I have a C# application which executes adb command to send SMS. It worked well on Android 8 (Samsung phone).

Untill recently I've upgraded my phone to Android 10.

The sending SMS command does nothing.

>adb shell service call isms 7 i32 0 s16 "com.android.mms.service" s16 "0123456789" s16 "null" s16 "Hello" s16 "null" s16 "null"

In the command line, it executes then returns an output: Result: Parcel(00000000 '....') but no SMS sent.

adb send SMS command does nothing on Android 10

Please help me to find where the problem is or any change since android 10. Many thanks.

P/S: My reference source is: Sending a SMS on Android through ADB - Stack Overflow
