AS网站目录（www.adminso.com）：三星 Galaxy Grand 2评测：实用靠谱中端机

Galaxy Grand 2是三星去年推出的中端大屏Android手机Grand的续作，5.25英寸显示屏按照今天的标准来看不算很大，但是它延续了Grand的实惠价格和双卡双待功能，并且与Grand相比有一些较大的提升：造型更纤薄、电池容量更大、处理器速度更快、显示屏也从480p变成720p。那么，Grand 2在实际使用中表现如何呢？请看我们的详细评测。

1.设计

Grand 2是一款宽窄适度的5.25英寸智能手机，而且也不算太厚，新款仿皮革后壳看上去挺有型但手感还是廉价的塑料感。

Galaxy Grand 2采用了三星在Note 3上首次采用的仿皮革拼缝设计，但是却没有Note 3那种像皮革一样柔软舒适的手感，而是给人以廉价的塑料感。不过，哪怕是最初级的仿皮革材质也比三星以前采用的光面塑料好，Grand 2后壳的纹理不容易显脏而且手感更佳。

在尺寸方面，Grand 2比Grand更加纤薄，厚度从9.6毫米减至8.9毫米，宽度从3.03英寸变成了2.96英寸，能让人更舒服地握在手里。此外，Grand 2组装得很结实，你用力紧握时也不会听到咯吱咯吱的响声。

Grand 2显示屏正下方有一个大大的实体Home按键，其两侧分别为触控式菜单和返回按键。其他实体按键位于手机侧面：锁屏键在右侧，音量调节键在左侧，它们都采用了平淡无奇的塑料材质，但是很容易够到也很好按。

2.显示屏

第一代Grand的粗糙显示屏不见了，取而代之的是Grand 2明亮、生动、锐利的5.25英寸720p显示屏。

Galaxy Grand 2配备了分辨率为720 x 1280像素的5.25英寸LCD显示屏，280ppi的像素密度还算令人满意，图片和文字看起来很锐利。如今更高端的手机都采用了比Grand 2锐利得多的显示屏，但是Grand 2的显示屏依然比第一代Grand大有提升，其本身就是一个很好的升级理由。

在色彩方面，Grand 2的显示屏相当对得起它的中端价位，生动鲜活的色彩在大多数用户看来都是加分项。但是在那些追求完美色彩精确度的人们看来，它的色调有一点偏冷，还有一点过饱和。可视角度偏窄，从较大角度观看时色彩会变得暗淡。

Grand 2的显示屏很亮，但是屏幕反光太严重，所以在室外读取内容很费力。但是，这款手机的最低屏幕亮度可以调至5 nits，从而方便用户在极弱的光线下或者在夜间舒适地读取内容，不会因为屏幕过亮而造成眼睛疲劳。

3.界面和功能

Android 4.3 Jelly Bean系统和去年的TouchWiz界面版本让我们觉得Galaxy Grand 2有点过时，但是它运行得不错，而且能很好地完成任务。

Galaxy Grand 2运行的不是最新版安卓操作系统KiKat，而是在旧版系统Android 4.3 Jelly Bean的基础上采用了三星一贯的TouchWiz界面。我们对Grand 2的就版型有点失望，但是也觉得三星很有希望在不远的将来将这款手机的系统升级至Android 4.4。

Grand 2上的TouchWiz也是我们非常熟悉的那个色彩鲜艳的旧版用户界面，而不是和Galaxy S5一样的新版界面，但是也具备了“Multi Window”多窗口管理器等三星定制界面的标志性功能。

在应用方面，Grand 2预装了三星“S”系列应用（S Planner、S Voice、S Translator），以及天气应用和文件管理器等三星自己开发的应用和小工具。

Grand 2的基本功能还是比较齐全的，通讯录功能丰富并且支持三星代表性的快速拨号和快速发短信滑动手势（在联系人姓名上向右滑动拨号，向左滑动发短信）。在大号显示屏上打字也很爽，而且输入表情符很方便。

4.处理器和内存

Snapdragon 400骁龙处理器是一个很大的进步，大多数时候都表现流畅，甚至可以运行最新的游戏，只是有时无法发挥最佳效果。

Galaxy Grand 2是一款中档手机，但是动力并不差，高通的Snapdragon 400四核骁龙处理器在日常使用中不会出现延迟或变慢。

这款四核芯片采用ARM的Cortex-A7架构，主频为1.2GHz――配上1.5GB的RAM内存和Adreno 305图形处理器（450MHz），这样的芯片组其实和摩托罗拉Moto G、LG G2 mini和诺基亚Lumia 630如出一辙，而它们都是速度相当快的中档手机。

大号显示屏对于游戏玩家无疑颇具吸引力，而好消息是Grand 2可以运行最新游戏，包括Google Play Store上的较大游戏。但是它毕竟不像高端手机那样给力，一些游戏发挥不出最佳效果。不过如果你对这一点不是特别介意的话，Grand 2可以充当一款经济适用型游戏手机。

需要注意一点：Grand 2的内部存储空间只有8GB，而用户可以支配的空间仅有大约5GB，所以你肯定需要外加microSD卡来扩展存储空间，最大可以扩展至64GB。

性能基准测试跑分

5.互联网和数据连接

网页在大屏上显示效果不错，而且大多数时候都能流畅地浏览。

如果你想浏览网页，Grand 2能让你选择三星定制的安卓浏览器或是谷歌的Chrome浏览器，它们都能迅速而高效地完成任务。不过，三星定制的浏览器提供的全屏模式可以最大程度地利用屏幕空间，而谷歌的Chrome浏览器具备跨设备同步功能和更好一点的界面。在两款浏览器上滚动查看以及放大缩小都比较流畅，只是偶尔出现一下卡顿。

在数据连接方面，Grand 2有三个版本：只有HSPA移动数据的G7100单卡版、同样仅支持HSPA数据连接的G7102双卡版，以及同时支持HSPA和4G LTE、下载速度最大可达到100Mbps的单卡版。我们在此进行评测的版本为HSPA单卡版，不过其他版本应该也没什么区别，而它们的价格也相差不多。

Grand 2还配备了双通道Wi-Fi、Bluetooth 4.0蓝牙、A-GPS，但是没有NFC。

6.相机

800万像素主摄像头捕捉的锐利图像在大多数情况下看起来不错，但有时色彩不对。1080p视频拍摄也锐利而流畅。

三星Galaxy Grand 2配备了800万像素自动对焦主摄像头、一个LED闪光灯以及200万像素前置摄像头。

800万像素主摄像头能拍摄画幅比例为4:3的照片，采用的镜头光圈为f/2.4。相机应用启动速度很快，界面是典型的三星风格，有全景、夜间和运动等拍摄模式，以及包括ISO和白平衡在内的多种手动调节设置（不过这些功能在菜单里藏得比较深，不方便快速调节）。

主摄像头拍摄的照片画质看起来相当精细，大多数时候颜色也不错，但是有时候色调会偏冷。总地来说，Grand 2的拍照质量在同价位手机中无疑高于平均水准，成像锐利、生动、噪点低，在室内以及在较弱光线下的表现也令人满意，色调接近自然的真实色彩，但是在采用高ISO时噪点会变得比较明显。

我们需要指出的不足之处是，对焦速度非常慢――在理想情况下需要耗时1秒钟左右锁定焦点，这没什么问题；但是有时候需要2秒钟甚至3秒钟才能对焦，这就让人觉得很慢了。而且对焦功能使用起来也有点麻烦――当你按下快门键，Grand 2无论是否对准焦点都会拍下一张照片，你得注意观察对焦情况（当屏幕上出现一个小方块并且从白色变为绿色时，就是对好焦了）然后再按快门，才能拍出准确对焦的照片。

▲Grand 2拍照样张――微距

相机应用也有HDR拍照模式，便于拍摄高动态光照渲染照片（例如在拍摄背对太阳或其他明亮背景的物体时），但是拍摄HDR速度较慢而且需要手比较稳。

200万像素前置摄像头对于自拍控来说是个不错的工具，而三星还包含了美颜模式，能对人像进行磨皮处理以遮盖皱纹等缺陷。

相机速度

▲从左到右各项依次为：拍一张照片（秒）、拍一张HDR照片（秒）、相机速度跑分、带闪光灯的相机速度跑分

摄像头能以每秒30帧的帧率拍摄分辨率最高达1080p的高清视频，拍摄的视频看上去流畅而锐利，但是也有一些小小的不足之处，包括不能连续自动对焦（需要你手动重新对焦）以及没有光学稳像（OIS）。视频的音质还算令人满意，但是并不算特别出众。

7.多媒体

Grand 2不支持某些多媒体格式，但是它的大号显示屏很适合用来观看视频。

Grand 2的5.25英寸显示屏很适合观看视频和浏览照片，三星的相册应用把你的照片分类存放在文件夹中，你可以方便地改动每一个文件夹的缩略图大小。Grand 2的视频播放器可以播放一些常见的视频格式，但是不能直接播放Xvid和DivX编码的视频，不过你从Google Play Store下载MXPlayer等免费视频播放器即可解决这个问题。
