Random Calling

[Android Central Question]

I have a Galaxy s8, sprint, about two months old... Whenever I'm in messages and lock my screen there's about 4 times out of 10 that my phone will start calling the person I was just texting. My phone will lock. Then pop up the call screen and begin the call. Most times I can cancel the call before it goes out but there are times said person will call back and say I called them. Is there a way to fix this, is this a common problem and/or is anyone else experiencing this problem?
