SPECIFIC ISSUE ENCOUNTERED

The Android Unity App will freeze after an amount of time running ARCore on the pixel range of phones. Tested so far with Pixel2XL, and Pixel3XL. It can happen within minutes or take up to 30 - 40 minutes. Not reliably repeatable but occurring very often.

This is running an IL2CPP build with ARM64.

Does not appear to occur on Samsung range. Tested with S8, S8+, S9+, S10+.

Repeatable in both our own AR app and Hello AR example.

VERSIONS USED

Unity: 2018.3.12f1
ARCore SDK for Unity: in both 1.9 and 1.10
Device manufacturer, model, and O/S: Pixel2XL, Pixel3XL, Anrdoid 9
ARCore: 1.9.190422066, 1.10.190603066
Output of adb shell getprop ro.build.fingerprint: google/taimen/taimen:9/PQ3A.190605.003/5524043:user/release-keys

STEPS TO REPRODUCE THE ISSUE

The Freeze happens quite often but no specific case to repeat. Can occur using the app or just having the phone stationary looking at a static environment. The more load on the phone the quicker it appears to happen. Reproduced on 2 different Pixel2XLs and a Pixel3XL.

WORKAROUNDS (IF ANY)

No known workaround.
