Some android vendors are struggling, because they fucked it up, plain and simple.

Who would buy LG, once they had one in past? Nobody, exactly, chalk it up to bad experience.

Who would buy HTC, if they had Thunderbolt in the past? Or how they didn't support their other models? Who would take risk with the HTC One? That would do only those, who weren't burned by HTC in the past.

See the trend?

Samsung, on the other hand, is successful, because their products are actually good. Someone who had SGS2 in the past has no reason to avoid Samsung in the future.
