I recently upgraded from a Galaxy Nexus to the Note 4. On the Nexus, I had issues receiving group texts and some regular texts but I just chalked that up to the phone being old. After upgrading, I didn't have the same problems at all. Until the last few days, that is.
Recently, there are texts that I have not been receiving from a few people. I only know this because they have gotten confused when I didn't respond. I am using the Chomp SMS app and the SMS & MMS settings seem to be ok, so I'm confused as to why this is happening. I also noticed that the issues are happening when I'm talking to users with iPhones. Please advise.
