IMS Droid calee是Ringing但屏幕是黑色的

Question

我使用Kamailio作为SIP服务器和IMS Droid（2.548.870 apk）作为Samsung Galaxy S4 mini的客户端。两个UE注册都很好并且呼叫邀请和振铃工作。但是被叫方没有用于接听电话的UI。相反，只显示通知，屏幕变黑。

我还试图找到IMS Droid活跃社区。有没有这样的？

Answer 1

这是仅针对特定设备/ Android版本的错误。 在另一台设备上尝试了相同的IMS Droid apk（小米Redmi Note 3）并且没关系：

为文档添加有缺陷的设备细节：

型号GT-I9195I

Android版本4.4.4

内核版本3.10.28-4321829 2015年4月3日
