Pros
Cons
三星为它的Galaxy Tab A7 (2016) SM-T280采用了非常紧凑轻盈的设计,它看上去几乎像是一台大屏手机。尽管它的机身完全为塑料材质,但防滑的机背设计仍然值得称赞。触控表面和屏幕面板之间的连接让人有些担心,在按压屏幕时它很容易就会出现水波纹。IPS的屏幕并不算特别出色,但也没有什么缺点。它所搭配的相机也是如此。尽管分辨率较低,但可以拍摄品质不错的照片。但是高品质视频拍摄就不是Galaxy Tab A7的长项了。
尽管硬件性能较低,但浏览照片、上网等基本使用在这台设备上可以流畅无阻。不过,这颗处理器在遇到需求较高的应用程序或者复杂网站时就有些捉襟见肘了。用户需要注意到它较为紧张的存储空间,幸运的是它可以通过支持App2SD的micro-SD卡槽扩展。
Galaxy Tab A7不是一台可以满足对性能需求很高的用户的设备。不过,它为日常使用提供了足够的动力,相机和屏幕在这个价位上都算是非常实用。
这台测试机目前的市场价为135欧元(约991人民币)。需要更实惠设备的用户可以考虑亚马逊的Fire平板电脑,它目前起售价约60欧元(约440人民币)。不过,用户需要接受品质较低的机身,低分辨率屏幕以及为亚马逊服务优化的操作系统。
