Does the forum have a cell phone hacker section?
Mobile phone hacking questions, can I ask questions here?
1.Mobile phones whose batteries cannot be removed. After the phone is turned off, some programs of the phone continue to run. Is this ok?
2.一般情况下，手机显示屏正面顶部都有一个摄像头。这是手机使用者知道的摄像头。
假设，另外加装一个或多外摄像头在手机显示屏正面，使手机使用者不知道它存在。
手机开机后，这些隐藏摄像头一直在运行。这可以吗？
translation:
In general, there is a camera on the top of the front of the mobile phone display. This is the camera that mobile phone users know.
Suppose that one or more external cameras are additionally installed on the front of the mobile phone display, so that the mobile phone user does not know its existence.
After the phone is turned on, these hidden cameras have been running. Is this ok?
sorry, there is no such section
your question seems to be off topic for this community
