FlowSensitivity does not better reflect flowsensitivity

[crawls-hub]

This is the code fragment I decompiled from the apk file:

@Override // android.app.Activity
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_flow_sensitivity);
    TelephonyManager tpm = (TelephonyManager) getSystemService("phone");
    String deviceId = tpm.getDeviceId();
    Log.e("FlowSensitivity1", deviceId);
    Log.e("FlowSensitivity2", "123");
}

From this code,it is clear that there will only raise 1 leak path whether the taint analysis tool is flow-sensitivity or not.
But however when I watched the source code of this apk,I find the original design of it really makes sense.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_flow_sensitivity);

    TelephonyManager tpm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
    String deviceId = tpm.getDeviceId();    // Source: <android.telephony.TelephonyManager: java.lang.String getDeviceId()> -> _SOURCE_
    Log.e("FlowSensitivity1", deviceId);    // Sink1, Leak: <android.util.Log: int e(java.lang.String,java.lang.String)> -> _SINK_

    deviceId = "123";
    Log.e("FlowSensitivity2", deviceId);    // Sink2, No leak: <android.util.Log: int e(java.lang.String,java.lang.String)> -> _SINK_
}

This code difference may be caused by compilation optimization which eliminates differences in analysis results.
Considering that much analysis will directly be put on the apk file,maybe a better one which can show the difference is expected.
