SH-12C无论用最低亮度或是自动亮度，晚上关灯后看网页都还是觉得刺眼。以前用Brightness Profiles:
https://play.google.com/store/apps/details?id=com.angrydoughnuts.android.brightprof&feature=search_result#?t=W10.
可以看到SH-12C的缺省最低亮度为8%。
打算在状态栏SystemUI.apk、 SystemUI.odex做修改。
1、用apkdb右键合并SystemUI.odex到SystemUI.apk
2、SearchMyFiles搜索brightness得知大概要修改ButtonAreaView.smali
3、
4、apkdb右键查看打包出来classes.dex源码
以及
5、修改很简单，将最低亮度值30改为0即可，当然在ButtonAreaView.smali里面为十六进制0x1e ---->0x00，有四个地方。
6、由于修改的是包含在odex里smali文件，所以回编译后要重新在手机odex化，并恢复旧签名：
重启后，状态右上角的亮度选择界面并无变化，但最低亮度改为0，可以用Brightness Profiles验证后删除Brightness Profiles。
晚上看手机舒服多了。{:96_526:}{:96_526:}{:96_526:}
