Yes, that was my immediate thought. I was a little surprised I could not find a named fallacy for it either, but the true fallacy is assuming different objects are the same. E.G. "no one else's soup has flies in it, therefore yours clearly does not either".
Something else that might apply here is Occam's Razor[1] (lex parsimoniae if you like Latin). The hypothesis that one device is broken is a simpler hypothesis than the one that all devices are broken.
