Funny, anyone would think it's the other way around seeing as Apple are constantly trying to sue Samsung, anyone would think they're threatened.And, you know, the iPhone is still the most popular single smartphone out there, period. How many Android phones are out there? How many Android phone manufacturers are out there? There's one iPhone. Every single one of those Android phone companies would KILL to have one phone that was even half, or maybe even a quarter as popular as the iPhone.
Also, The Galaxy S2 outsold the iPhone 4S for over 8 months, a device a year older that it. The Galaxy Ace also outsold the iPhone, and on contract the Galaxy S3 is currently outselling the iPhone 5.
So no, all of those Android companies wouldn't kill to have a phone like the iPhone, Samsung already have one, the Galaxy series.
Keep fooling yourself into thinking Apple is still the top dog in the phone world.
