Samsung Galaxy's a better phone? Look at this comparison. I would say they are very close. The bottom line is... Majority of consumers always go for the better name. Huawei is still new in the smartphone industry. But I think they will out beat other leading brands very soon with the quality budget style. Remember when HTC first launched with android, we was like "HTC"? Today they are know to majority of consumers.
I think Huawei need to avoid doing what HTC did at all costs. My last phone was an HTC Hero, flagship phone when I first got it, they dropped it like a hot potato within months. They were an OEM manufacturer that had ambitions to become a 'brand' like Samsung and Apple, but they flooded the market with an endless array of models without building up a proper back-end and support infrastructure. Look at them now, struggling to compete with Samsung and Apple and a share price at a 12 month low.
I can see Huawei doing the exact same thing if they aren't careful.
