Not detecting changes in the among call states.

[ctp]

Hi,

I have an application that needs to detect changes in the call state (idle, ringing offhook) but yersterday a user sent me the log of the application and I realized that in MIUI those state changes are not broadcast and thus my app is not working properly.

I am not sure if this could be about the MIUI version but this is the description of the mobile where the test was performed:
Mobile: HTC Incredible android 2.3.5
ROM: MIUI 1.9.2

Does anyone know if this is a known issue or if there is a workaround?

Thanks!
