Are you able to reproduce this yourself? I’d try and see if there are some similarities that trigger a restart, such as displaying too many images at once, which can overwhelm the device.
Also, you can integrate a framework such as Fabric & Crashlytics which should help you dig in to see what prompted the restart.
Thanks! Fabric seems to only support Native development. I can’t seem to get past the onboarding screens because there is no option for cross platforms. Just ios, android and Unity
The link I shared is for a Fabric Cordova plugin and I have implemented it in a few of my own hybrid apps. It can take a little configuring, but that is the plugin I use.
