My S7 all of a sudden stopped receiving text messages. It was fine through a short conversation thread. After an hour of stepping away, it wouldn't let me receive texts from the exact same thread-the other person was getting my texts the whole time. Also, my Galaxy 4 has WAY better service-I can't understand this as nothing has changed about my service except the phone. My S7 drops calls fairly frequently, has trouble connecting to WIFI and recognizing locations-the wifi continuosly searches and I have to do a restart to allow any activity, and it has quite a bit of trouble sending text messages-especially with pics attached-in the same places my 4 had absolutely no trouble. So confused and super frustrated.
