ColorSageSorry, I forgot about this thread. If a factory reset won't fix the above issue, then you need to send it for repair. Maybe you have already?
I've tested Antutu Benchmark, some other kinds of GPU bencharks, Asphalt 9 and Mortal Kombat X. Basically every 3d-intensive application. Exact moment of crashing is varying but usually I can see some weird screen stuttering since the beginning of a 3D scene and after 10 seconds or so the app crashes.
