And here is what's happening.
Caption from my video on YouTube.
This is a video clip of my Google Pixel 2 which I personally feel has a hardware problem. While I am only showing this singular application (does not commute), this will happen within some other games, and video editing Applications.
Google Support states this is not a hardware problem, it is due to application stability. That's fine, but still unacceptable that an application can fully shut down the phone.
Other apps that can cause this (not as reliably though)
- Star Trek Timelines
- FilmoraGo
- 3D Bench Slingshot.
Phone is fully stock Android from Google, with all available updates installed.
