Funny... and thanks for the constructive reply.
But, I've owned a ton of handsets over the years. Have you really ever had to repair the preinstalled ROM because of failing phone and SMS functions? I can't really think of another phone where this has happened.
The question is more as to why? I've filled up the installed memory enough as to have to delete apps and data to get below the recommended 75%. Maybe that corrupted the phone's memory? I can't say, but again, this is a first. And, I have never been one to complain about all the other small things out there (camera, overheating, misaligned glass, single speakre output, etc).
I do expect to be able to make calls consistently, though.
