Samsung (and possibly other phones) do not allow "dangerous" actions such as RECORD_AUDIO to be invoked unless they are coming from a Thread your process owns. This means that if you are trying to invoke from a Binder thread or other IPC thread, the request will fail with the permission error, even if your app has accepted all relevant permissions. It's a good security measure, but they could add some logging b/c it's unclear why the failure.

Try spawning another thread via a Handler() or using Activiy.runOnUiThread() and invoking startRecord() there.

Start the startRecording() method of AudioRecord class with some delay after creating the Audiorecord instance:

        public void start() {
        // Stop recording if it is currently ongoing.
                stop();
                // Try to create a new recording session.
                mAudioRecord = createAudioRecord();
                CommonMethods.printLog(TAG, mAudioRecord.toString());
                if (mAudioRecord == null) {
                    throw new RuntimeException("Cannot instantiate VoiceRecorder");
                }
                // Start recording.

                if (getDeviceManufacturer().contains("samsung")) {
                    new Handler(Looper.getMainLooper()).post(new Runnable() {
                        @Override
                        public void run() {
                            new CountDownTimer(100, 50) {
                                @Override
                                public void onTick(long millisUntilFinished) {

                                }

                                @Override
                                public void onFinish() {
                                    mAudioRecord.startRecording();
                                    // Start processing the captured audio.
                                    mThread = new Thread(new ProcessVoice());
                                    mThread.start();
                                }
                            }.start();
                        }
                    });
                } 
            }

     private AudioRecord createAudioRecord() {
            for (int sampleRate : SAMPLE_RATE_CANDIDATES) {
                final int sizeInBytes = AudioRecord.getMinBufferSize(sampleRate, CHANNEL, ENCODING);
                if (sizeInBytes == AudioRecord.ERROR_BAD_VALUE) {
                    continue;
                }
                final AudioRecord audioRecord = new AudioRecord(MediaRecorder.AudioSource.MIC,
                        sampleRate, CHANNEL, ENCODING, sizeInBytes);
                if (audioRecord.getState() == AudioRecord.STATE_INITIALIZED) {
                    mBuffer = new byte[sizeInBytes];
                    return audioRecord;
                } else {
                    audioRecord.release();
                }
            }
            return null;
        }

 private String getDeviceManufacturer() {
        String deviceManufacturer = android.os.Build.MANUFACTURER;
        return deviceManufacturer;
    }

Use PermissionChecker.checkCallingOrSelfPermission it should do the job.

if (PermissionChecker.checkCallingOrSelfPermission(this, Manifest.permission.RECORD_AUDIO)
            == PackageManager.PERMISSION_GRANTED) {

       //Start recognition

    } else if (ActivityCompat.shouldShowRequestPermissionRationale(this,
            Manifest.permission.RECORD_AUDIO)) {

            // show permission dialog.
        showPermissionMessageDialog();
    } else {

         //Request permission.
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.RECORD_AUDIO},
                REQUEST_RECORD_AUDIO_PERMISSION);
    }
