如何鉴定手机的好坏？
手机的好坏是要从多方面去鉴别的。分为以下几点可以给题主做参考：
1、系统
IOS与安卓的区别相信大家也知道，安卓因为其开源性导致无意间下到流氓软件，让自己苦不堪言！而IOS，没经过同意，是不会被任何流氓软件困扰的！
MIUI、Flyme、锤子系统都属于安卓的优化系统，像MIUI、Flyme评价都还不错，锤子系统因为太过接近IOS而令人诟病。
2、CPU
CPU通俗一点地说就是处理器，处理器相信有很多人知道代表什么，处理器越好代表性能越优秀，而且不是处理器越多就一定代表的越好。
举个例子：当时iPhone 6s出来的时候是A9双核处理器，半年之手Galaxy s7的高通骁龙820的四核处理器还不一定是对手。
大家还要知道的事，vivo跟oppo所用的处理器其实是略次于手机价格的。当然如果你对游戏这方面没有太大的需求，vivo、oppo还是没问题的！
3、不要购买第一批手机！
很多手机刚出来的时候会有些许bug，一般都不介意人买第一批手机，买到批次有问题的手机，能不能是一回事，重点是很麻烦！你愿意买了新手机还要考虑这种问题吗？
如果下定决心想要买哪款手机的话，不如等一两个月再看看有没有什么负面新闻再决定吧！
当然了，除了上述几点供参考的还有手机屏幕、手机材质等一些其它的小方面的问题！
最后奉劝大家，不是行家不要买二手手机，虽然有些二手手机质量不错，但是雷区还是很多的！手机小白很容易成为别人宰割的对象！
