推荐答案

在某些设备上基于Snapdragon 805，你可以。在其他情况下，制造商选择阻止朴素的方法，但本机相机应用程序知道如何做到，并与一些逆向工程努力，你可以重现他们的方法（我已经部分成功与三星S4之前，我失去了兴趣

On some devices, e.g. based on Snapdragon 805, you simply can. In other cases, the manufacturer chose to block the naïve approach, but the native camera app knows how to do it, and, with some reverse engineering effort, you can reproduce their approach (I had partial success with Samsung S4 before I lost interest in that project).

但是在大​​多数可用的手机上，有一个物理限制：两个相机共享相同的总线，不能同时打开，无论多么巧妙你在软件。

But on most of available phones, there is a physical restriction: the two cameras share the same bus, and cannot be opened simultaneously, no matter how skillful you are in software.
