Hi,
I’m developing an app on my iPhone 6s and this occurs quite often, causing me have to restart expo.
While running the expo app, my iPhone is stuck at 100% CPU usage.
Is there any way I can fix this?
The performance Monitor shows the following:
RAM: 300MB
JSC: 0MB
Views: 2023 / 2571
UI: 60FPS
JS: 60FPS
Although I had to use a separate app to monitor CPU usage.
The following crash log was retrieved from the device using iTools
