三星 Galaxy Alpha SM-G850F 智能手机简短评测

Name: Samsung Galaxy Alpha
Brand: Samsung

阿尔法领航者。 三星一直以来即使是高端产品也只使用了塑料材质机身。不过这次有些不同了，他们新发布的Galaxy Alpha智能手机采用了铝合金的边框。这款智能手机携着强大的硬件向顶级智能机的王冠发起了冲击，不过这个王冠依然属于同门师兄——Galaxy S5。

三星推出了一款硬件配置十分强大的高端智能手机：Galaxy Alpha。尽管它类似于三星的Galaxy S5，但也有很明显的不同。它的机身制造工艺和材质都得到了改进，而32GB的闪存容量也很可能是三星为Galaxy Alpha定价提高50欧元，达649欧元的原因之一。它的机身有坚固的金属边框和优雅的设计。而内部组件也十分令人艳羡。一颗非常节能又足够强劲的三星八核处理器协同高达2GB的内存提供十分优秀的表现——尽管Galaxy S5有更加强大的配置。另一方面，它的4.7寸Super AMOLED屏幕非常出色。必须承认的是，它720p的分辨率略低，不过也可以满足实际的实用。由于设计优秀的TouchWiz界面，它的系统非常便于操作，而最新的安卓4.4.4 KitKat和众多的运行选项也让我们十分满意。它的整体配置可以说是物超所值：高速的Wi-Fi模组，NFC，全能的通信模组，还有不错的相机。这个相机在暗光下的拍摄较差，不过也情有可原。而长电池续航，和指纹识别器提供的安全保障都可以弥补这点不足。它的语音通话质量也十分出色。它最大的一个问题在于：三星在Galaxy Alpha中去掉了存储卡槽的设计。因此，需要大于25GB（可用空间）的闪存的用户可能需要考虑使用额外的云储存空间。

三星的Galaxy Alpha整体上可以说是高端产品市场上一个有趣的新竞争者。在这个价位上，现在有不少值得考虑的选择。除了苹果 iPhone 5s and iPhone 6 之外它最有力的竞争者大概是同样来自三星的Galaxy S5了。S5现在的售价约500欧元。我们推荐偏好坚固、轻巧的艺术品级金属机身，又能够接受我们之前提到的缺点的用户考虑这款产品。
