Front Camera2 API GLSurfaceview

I'm trying to access the front facing camera through the Camera2 API using an actual device

the problem occurs when trying to

cameraManager.openCamera(..,..,..)

try {
        CameraCharacteristics characteristics = manager.getCameraCharacteristics(mCameraID);
            if (!mCameraOpenCloseLock.tryAcquire(2500, TimeUnit.MILLISECONDS)) {
                throw new RuntimeException("Time out waiting to lock camera opening.");
            }
            manager.openCamera(mCameraID, mStateCallback, mBackgroundHandler);
        } catch (CameraAccessException e) {
            Log.e("mr", "OpenCamera - Camera Access Exception");
        } catch (IllegalArgumentException e) {
            Log.e("mr", "OpenCamera - Illegal Argument Exception");
        } catch (SecurityException e) {
            e.printStackTrace();
            Log.e("mr", "OpenCamera - Security Exception:");
        } catch (InterruptedException e) {
            Log.e("mr", "OpenCamera - Interrupted Exception");
        }

the Cameramanager says

I/CameraManagerGlobal: Connecting to camera service

which is coming from this CameraManager.java function

private void connectCameraServiceLocked() {
            // Only reconnect if necessary
            if (mCameraService != null) return;

            Log.i(TAG, "Connecting to camera service");

Then my GLSurfaceView remains blank

AndroidMainfest.xml

    <uses-permission android:name="android.permission.CAMERA" />
    <uses-feature android:name="android.hardware.camera" />
    <uses-feature android:name="android.hardware.camera.autofocus" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="com.google.android.permission.PROVIDE_BACKGROUND" />

    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" />

P.S:

• It works with the back camera
• It works with the nexus 6 API 23 emulator
• Permissions are requested at runtime for Android M
• I'm using GLSurfaceView as a viewfinder
• The front camera was working perfectly on the same device using the normal CameraAPI with a TextureView
• Tried to Uninstall/Reboot/Clear Cache
• the device I'm using is a Sony Z5 premium

I'm using this example Render camera preview using OpenGL ES 2.0 on Android API 21 or higher

I've ended with changing the Sony Xperia Z5 premium to another device and it worked perfectly. it looks like that Sony is facing some problems with the new API as i saw in the following link:

Sony Camera2 API limitations

there might be a work around but anyway i'm making an application for specific purpose i don't want it to be working on all devices
