    Hi,

    I'm trying to develop an AR App in android with Unity AR Foundation.

    I've added a tracked image prefab with 4 objects for image tracking. The App runs smoothly in the beginning but will get a frozen screen after 10 - 12 minutes. Accroding to Profiler Tablet CPU usage jumps from 1-10 ms to 1400 ms and more (40s). The top 3 events are: "EarlyUpdate.PresentBeforeUpdate", "Graphics.PresentSync" and "Device.Present". I don't know what these three events represent. Details see picture

    I also tried to build a new project with simple AR scene without any script, but this problem still exists.

    Any help is appreciated

    Unity version: 2021.1.2f1
    device: Samsung S6 Lite with Android-version 11
