iPhone 16e randomly types conversations in text messages

I just got this iPhone 16e from Boost mobile about 2-3 weeks ago brand new I was told at least. The last almost week, apps I was currently using would close out for no reason and I know I didn’t push anything that would have made the apps completely close out. It’s not only ONE app that has been crashing or closing itself but it’s been many.

Then we have what started happening this afternoon out of nowhere. I was with my daughter in my car and texting my husband who was working. I typed out what I wanted to say and send it but got distracted by my daughters questions leaving the phone unlocked screen on and ready to text my husband I’m he responded. It made me jump when I glance at my phone for a second and watched my phone typing a message to my husband without my hands on the keyboard. Then I noticed what was typed was the conversation with my daughter and I. I saw a new icon or whatever you call it and that was blue. It was top three right of the time in the upper left corner. I thought it was the voice over or something like that and I made sure nothing was on that wasn’t supposed to be. I did screenshot a picture of what the icon that had showed up out of nowhere looks like if anyone has answers!! And would greatly appreciate any theories or advice about my apps crashing lately too. Thanks!
