Apple Insider reports that Samsung’s #Galaxy11 viral campaign fumbles when Franz Beckenbauer tweets from iPhone. The football legend was the manager of Samsung’s Galaxy 11 dream team.

It is not the first time that celebrities who endorse Samsung actually use an iPhone.

John Legere:

Sending promotional tweets about other products from Apple’s iOS devices seems to be quite popular. In October, T-Mobile chief executive John Legere intended to use Twitter to direct attention to Samsung Mobile’s latest Note 3 phablet, but inadvertently did so via his new iPhone 5s.

David Ferrer:

Shortly afterward in April, Spanish tennis player David Ferrer tweeted his satisfaction with his #GalaxyS4 and that he was “configuring S Health on my new #GalaxyS4 to help with training @SamsungMobile,” all via Twitter from his que contento estoy con mi iPhone.

Oprah Winfrey:

Last year, Oprah Winfrey used an iPad to send out tweets endorsing Microsoft’s Surface, using the hashtag “#FavoriteThings” to say she had bought a dozen of them for Christmas gifts.
