In the past I had a Samsung Stratosphere I and I recently purchased this Droid Razr Maxx. However, on both smartphones, I've seemed to be experiencing the same problem, and that is that it often loses messages from iPhones. I would be having a conversation with someone and I would usually end up sending the last text message and not hearing back from the other person because I do not receive their text message. This also sometimes happens with other android phones, not only iPhones.
I want to understand why this happens. It happens about once a day and it's been occurring for the past few years now!
