Received this morning, works very well with Galaxy Note 3 of 'vieux''vidéoprojecteur VGA 800x600 on projection screen 200x150cm. Tested with low and high quality videos from SD card (Samsung drive) from Youtube, Dailymotion, application B-TV (Bouygues TV) and connected audio output to stereo amplifier (without it, the sound still comes out of the smartphone). Same Galaxy s3. Hopefully, image and nickel! Always the system is supplied with electricity, so power is on. WARNING: However, do not work on Galaxy Note 1 because the micro usb plug adapter that connects to the phone is too long for decision MHL / micro USB Female smartphone, so connecting and charging Power will not do! Annoying for me because it is precisely the Note 1 I wanted sacrificed cinema station ... Maybe there are micro Usb / micro usb?
