 To have this reboot save, one have to install an autostart app to run the "Recorder" app after boot. The autostart app is available in the aptoide store – which comes with the default firmware. To have this reboot save, one have to install an autostart app to run the "Recorder" app after boot.

 +## Bild Rot/Grün/Schwarz an Decklink MiniRecorder
 +
 +Wir haben öfters das Problem beobachtet, dass die Bildausgabe des Tronsmart am HDMI-In einer Decklink MiniRecorder komplett Dunkelrot, Dunkelgrün oder komplett Schwarz ist, obwohl der Tronsmart nachweißlich auf die korrekte Auflösung eingestellt ist und am Beamer oder Fernseher korrekt funktioniert. Das Problem kann durch zwischenschalten des HDMI-to-SDI-Wandlers und grabben der Slides vom SDI-In der MiniRecorder behoben werden.
 +
 +Tests zeigten, dass manchmal das Tauschen des HDMI-Kabels hilft, manchmal aber auch nicht. Auch das Tauschen des Tronsmarts hilft nicht immer. Diese Beobachtungen legen nahe, dass das Problem nicht alleine am Kabel noch am Tronsmart und vmtl. auch nicht an der Karte liegt. Warscheinlicher ist eine Kombination der Faktoren mit Umgebungs-RF, Temperatur, Shielding oä.
