**ATTENTION: The new ESP32 camera hardware driver is much more stable on newer OV2640 versions (no or much less reboots) but seems to be not fully compatible with older versions.**
If you have problem with stalled systems you can try the following
- Update the parameter `ImageQuality` to `12` instead of current value `5` (manually in the `config.ini`)
- If this is not helping, you might need to update your hardware or stay with version 9.2
