We aren't sure what to make of this rumint. Supposedly, the upcoming Samsung premium device called the Galaxy Alpha will only come with a 720P display. According to supposedly confirmed info, the Galaxy Alpha's display will be 4.7-inch and will sport a 1280 x 720 resolution.
The source of this rumor speculates that it will have a PPI of 306. Considering this device will supposedly be launched to compete directly with the new 4.7-inch iPhone 6, it seems perplexing that Sammy would release it with a potentially inferior screen. The only theory we could come up with is that maybe this device will come with Samsung's new YOUM flexible display technology and the lower resolution is a technical requirement in order to make it in quantity.
The question remains, will the plastic display be an adequate enough marketing gimmick to make up for its resolution deficiencies?
Of course, at this point it's all speculation, so feel free to throw your perspective in the ring.
