Cannot report app crashes
If you want to report crash, you can do using other way :

When app crash, go to 


  Phone Dialer -> Dial *#9900# keystring -> Dial


This will open Dumpsys terminal, then click Run Dumpstate and this application terminal will capture logs in background for you.

Now, you just need to attach the file from /log/dumpstate_ddmmyyhhmmss file as crash report.
