Unhappy Text messages being cutoff

Not sure if this belongs here, but here it goes.


About a few weeks ago, I started getting text messages from my boyfriend, but they were cutting off after around 160ish characters. The second text box was received was empty. I've included an example in the picture attached.

No one else texts me that much other than him, so I am not sure if it is just his number causing me this.

A week after this started happening, the problem got worst on my phone, when the stock messaging app, started crashing randomly. Later on, I would get the same message received, double.

T-mobile released the phone, saying they had received there were problems with a small number of S5.

I got the replacement phone yesterday. I was texting my boyfriend last night, when the message got cutoff again.
