Es wird von Problemen des Windows Phone 8 Smartphones Lumia 920 im Zusammenhang mit der Synchronisation von E-Mails und Twitter berichtet. So soll es vorkommen, dass das Lumia 920 in einer Synchronisations-Endlosschleiße hängen bleibt. Sollten Kontakte bearbeitet werden bricht der Vorgang ab und der Nutzer landet im Windows Phone Startbildschirm. Wird das Smartphone dann – in der Hoffnung den Bug zu beheben – zurückgesetzt kann es vorkommen, dass das Gerät sich aufhängt und – ist der Akku leergesauft – abschaltet. Für das Problem soll angeblich die Skype-App verantwortlich sein, tritt also oben beschriebenes Verhalten auf bitte zunächst die Skype-App deinstallieren bevor weitere Schritte eingeleitet werden.

Wurde das Handy allerdings zurückgesetzt und hängt es sich während dieses Vorgangs auf kann es wie in nachfolgender Videoanleitung (ROM flashen) wiederbelebt werden:
