Ever since updating to Android 4.3, I have had odd problems sending picture messages. I have delivery confirmation turned on, and I can tell that certain pictures taken from my camera will send, but never be received by my contacts. The message status will say 'sent', but delivery confirmation will just say 'requested', instead of actually confirming that it was sent and received. There is not a size issue, as pictures ranging from 4kb to 1200 kb will inconsistently send or not send.
I do not have wifi turned on, I do not have any third party messaging apps, and I am running the latest software as per software update.
Is this a problem born from updating to 4.3, or a newly discovering problem with my phone?
