三星s8虹膜解锁晚上怎么办
三星s8虹膜解锁晚上怎么办？
个人感觉虹膜识别日常生活中作用不大
自用note9
个人使用一般情况下，白天，大多数情况手指头有汗，我解锁手机的时候都是按一下home键的位置然后对着屏幕看他就解锁了（那里有压感，类似于iPhone的3d touch那种），我是用的是混合解锁，脸部跟虹膜一起扫的人人店三级分销源码那种，我都不知道他到底有没有认真的检查过我的虹膜，就是识别器闪一会就进入了，但是识别速度真不如国产众机，不过也不是慢到无法忍受那种，感觉解锁的时候有锁屏界面闪一下更有仪式感和安全感（我脑回路可能有问题）
晚上光线暗一些，我就直接指纹识别解锁了，很简单锁屏的时候按一下识别器直接进入
仔细思考了一下，s的好看的404页面源码屏幕指纹其实也不错，反正我也是要用虚拟home键点亮屏幕的，s把指纹跟home键结合了可以提升解锁速度，而且如果我用s，白天晚上就不用换着传感器解锁了，况且超声波指纹安全性也算是比较高的，毕竟国家机密或者公司源代码一般人是不会存到手机里的，所以没多大必要整一些安全度极高的识别方式

哪些手机是安卓7.1系统
大部分安卓手机品牌都是7.1系统。Android 是运行于 Linux kernel之上，但并不是GNU/Linux。因为在一般GNU/Linux 里支持的功能，Android 大都没有支持，包括Cairo、X、Alsa、FFmpeg、GTK、Pango及Glibc等都被移除掉了。
Android又以bionic 取代Glibc、以Skia 取代Cairo、再以opencore 取代FFmpeg 等等。Android 为了达到商业应用，必须移除被GNU GPL授权证所约束的部份，例如Android将驱动程序移到 userspace，使得Linux driver 与 Linux kernel彻底分开。
bionic/libc/kernel/ 并非标准的kernel header files。Android 的 kernel header 是利用工具由 Linux kernel header 所产生的，这样做是为了保留常数、数据结构与宏。
Android 的 Linux kernel控制包括安全（Security），存储器管理（Memory Management），程序管理（Process Management），网络堆栈（Network Stack），驱动程序模型（Driver Model）等。下载Android源码之前，先要安装其构建工具 Repo来初始化源码。Repo 是 Android 用来辅助Git工作的一个工具。
