I have had problems for the last 1 1/2 years with this phone regarding group MMS messaging. Most of my friends have iPhones and they always do group iMessage. I know that Samsung S1-4 phones work very well with group messaging, but LG does not. The stock messaging app does not support it. I downloaded Go SMS Pro last summer and after some research and changing some settings, I was able to get group messaging! It would show as a download MMS message in their individual thread, automatically download it and then place the message into the group thread. Unfortunately when Sprint upgraded to 4G LTE, the MMS would not download out of the individual thread. I went to Sprint, and they told me that 4G LTE is still a "baby" and when I get group messages, to switch to the 3G CDMA network for them to download. Annoying, but it worked. Now my new problem is in the last couple of months, my friends with Windows Phone through Verizon come up as blank texts in my group thread once downloaded. If they send a picture MMS, I see that in the group thread, but not a simple text MMS. I've spent hours on the phone with Sprint with no success. I've uninstalled Go SMS Pro and reinstalled, no success. I've tried other text apps, they don't support group MMS on my phone. Any ideas or advice would be greatly appreciated!
