Text Chat thread keeps closing by itself

[michail71]

I have on contact that has issues on the SMS/Text thread. It will often close a few seconds after I open the contact for messaging. I was thinking I was hitting the back or home button by accident until I saw it do it today without my fingers near the phone. Going back in a second time seems to work.

What device do you have?

A Lumia 1520.

It was a rather long text thread so I deleted it. Perhaps that will solve the problem.
