samsung devices not focus
I can see that for a plenty of Samsung devices the camera cannot auto-focus for some reason.
/**
* Inits the camera view
*/
private void initCamera() {
//creates the config for the camera
RxCameraConfig config = RxCameraConfigChooser.obtain().
useBackCamera().
setPreferPreviewSize(new Point(640, 480), true).
setAutoFocus(true).
setHandleSurfaceEvent(true).
get();
// opens the camera
RxCamera.open(getContext(), config).flatMap(new Func1<RxCamera, Observable<RxCamera>>() {
@Override public Observable<RxCamera> call(RxCamera rxCamera) {
return rxCamera.bindTexture(camTextureView);
}
}).flatMap(new Func1<RxCamera, Observable<RxCamera>>() {
@Override public Observable<RxCamera> call(RxCamera rxCamera) {
return rxCamera.startPreview();
}
}).observeOn(new UIThread().getScheduler()).subscribe(new Subscriber<RxCamera>() {
@Override public void onCompleted() {
}
@Override public void onError(Throwable e) {
}
@Override public void onNext(RxCamera rxCamera) {
rxCamera = rxCamera;
}
});
}
In general seems that camera doesn't focus in any device and it's a problem
your devices may not support FOCUS_MODE_AUTO, you can try to use areaFocusAction to set the focus area
@ragnraok users are complaining and the device is Samsung Galaxy S7. As you understand it's very difficult to not support FOCUS_MODE_AUTO such a device.
Hi, have you try the focus mode FOCUS_MODE_CONTINUOUS_VIDEO or FOCUS_MODE_CONTINUOUS_PICTURE, it may better for the long term services such as barcode scanning or voip
