My father has a Samsung Gusto. For the past few months, he occasionally receives texts from me (iPhone) that are blank. Other times, he will receive only part of my texts. Still other times he receives the complete texts. Tonight we tested texts from my husband's phone (also iPhone) and got the same results. Here's what we've tried: restarted his phone, took out battery and replaced, reset his phone with *228 Does anyone have any suggestions?
