No.

But you should see something in the logcat that shows an intent was
fired. Do you not see that? The system does not "drop intents
randomly". Can you point out concrete cases where it has without
sufficient error messages, because those would be bugs..

There's not logged output from the Android internals that give an
account of why your intent is "dropped" but I am more confused as to
why this would be happening in the first place. In the past, whenever
I've heard this happening, it's because there's always been something
like a misspelling of package name, or something's been signed
incorrectly..
