I have exact same issue with Chomp and also Textra. When using default Messages app on my Note4 I receive a nice large image appox 1 Mb. But on chomp I receive less that 30kb image for same image from same sender. It always seems to be 480 pixel image I receive.

Seems to happen only with verizon to verizon network mms images using Chomp. I'm on verizon mnvo My Time Wireless. Sender is on verizon mnvo Puppy Wireless. Also receive tiny image when I send to myself.

However, my other friend sends me images from his TMobile to me and I receive full imagr near 1Mb.

Please fix this
Thank you
