Question [Q] [Help!]Strange bug launching call log

Hello all. I am rooted, running xposed module (stock otherwise), and twice now my phone has developed this problem.

With the screen unlocked, it seems to randomly jump to the call log screen.

The First time this happened, I tried disabling xposed module, clearing the cache, etc. Problem persisted. I factory reset and it seemed to clear everything up. Installed xposed again and no problems for a few days. Then, about 4 days later, I'm experiencing the same problem again. Didn't seem to coincide with installation of an app, enabling a feature, etc.

Any way for me to diagnose this or any experience with a similar problem?

Thanks
