手机上这几个功能，简直太方便了，你的手机有吗？
随着智能手机的不断普及，国内智能手机现在几乎人手一部甚至多部，智能手机的性能也越来越强，内存越来越大，屏幕越来越大，功能也越来越多。
今天，给大家说一说手机里面比较实用的几个小功能。
应用分身
应用分身，就是指能将一个应用复制，同时在手机上产生两个（或多个）相同的APP。
如两个QQ，这是很实用的，因为很多人都会有QQ小号，使用应用分身后，就不用频繁的切换账号，可以同时多个账号在线，其它的微信等应用也是如此。
红外遥控
这个功能就更厉害了，它可以替代家里日常使用的大部分遥控器，如空调、电视、机顶盒、音响等。
现在我们看电视的时间越来越少，经常会忘了电视遥控器在哪儿，有了红外遥控功能，这都不是问题，手机打开就能解决，比原装遥控器还方便。随着智能家居的普及，手机中红外遥控能使用的场景越来越多。
语音唤醒
这个功能可能用过的人不多，是通过在手机中预置唤醒词，当用户发出该语音指令时，设备便从休眠状态中被唤醒，并作出震动和响铃的行为。
在家里的时候，我们会常常找不到手机，又没有办法给自己的手机打电话，这个功能就很贴心了，喊出你手机的名字，它就会回应你，让你找到它。
NFC
这是个很多人天天用，很多人从不用的功能。NFC指的是近距离无线通讯技术。
一般的NFC分为卡模式、读卡器模式、点对点模式。
主要用途有接触通过、接触支付、接触浏览、接触连接、接触下载等。有了这些功能，手机可以当作门卡、门票、公交卡、支付卡等很多功能，对城里的使用者来说很是方便。
热点
手机热点，就是将手机作为路由器，共享流量给其它设备。
比如，手机卡是无限流量的，想用平板看视频，又没有wifi，就可以通过手机设置热点，就能用平板享受手机的流量了。
之前坐火车的时候，就有一位小哥哥手机欠费上不了网，也交不了话费，就让我给他开了热点，它顺利的交上了话费，所以这个功能还是挺有用的。
好啦，今天就说这五个比较实用的功能了，其实目前我也想不到了，哈哈。感谢大家阅读，欢迎留言讨论。
