I am still having trouble texting (sending) videos. I have gone into my camera settings and changed the limit for MMS it will send only recent videos and not the ones I have on my phone. Also I am having trouble downloading the video to my computer.
I can send videos fine, even if I don't set it to mms, it automatically converts it for me if it's too large. When you say it works for recent videos and not old ones, you mean it works only if the video was actually recorded using your s3?
