手机硬件操作系统的控制级别
我是 Android 和手机开发的新手。我想开发一个需要完全控制智能手机“电话”的应用程序,即控制 GSM 芯片与蜂窝系统的所有通信,访问它发送(加密)到蜂窝系统的 SIM 卡身份系统,禁用蜂窝天线并恢复它,等等...... 安卓可以实现吗?软件(操作系统)是否可以控制智能手机中的所有电话组件,或者某些部分仅在硬件级别完成? (我猜 Android API 不会让我做我想做的一切,但即使在理论上,如果我在进行更改后重新编译操作系统,是否有可能?) 谢谢!
I am new to Android and mobile phones development. I want to develop an application that needs to have a total control over the "phone" of the smartphone, i.e. controlling all the communication of the GSM chip with the cellular system, accessing the SIM card identity that it sends (encrypted) to the cellular system, disabling the cellular antenna and resuming it back, and more of that kind...
Can it be done with Android? Does the software (OS) have control over all of the phone components in a smartphone, or there are some parts that are done in the hardware level only? (I guess that the Android API won't enable me to do everything i want, but even theoretically is it possible if I recompile the OS after making the changes there?)
Thanks!

是的,使用自定义固件一切皆有可能。
Yes everything is possible with custom firmware.
