Thanks for the simpler fix Justin! I've done a hard reset on my phone and updated the registry values above and tested sending/receiving larger pics without a problem. I updated my 1st page to include a direct link to your Post #42 and updated the thread title as well.
Now for another quirk lol. Is there any way with the stock Samsun messaging (non-threaded conversations) to have MMS and SMS go to just one freakin Inbox? Arcsoft received all SMS and MMS into one Inbox and I really got used to that. Now if I could get the Samsung messaging to do the same I'd be a much happier person!
