Check if your phone's diagnostic mode has been activated;
For safety, make sure your smartphone has installed the external SD card;
Make sure when running MMDiag, your phones are exchanging messages with the network. As a quick test, you can switch on the airplane mode and switch off and check whether cellular messages are generated.
我的手机进入diagnostic模式后打开NetLoggerMMDiag没有收集到蜂窝网络的信息,请问有什么可能的原原因?
