Sometimes a black screen

[JoJaMa712]

Sometimes the browser shown a black screen like picture 1 but the serial monitor shown no error (picture 2). It seems that the camera is working correctly
I have the same problem with a ESP32-Dev-Board with OV2640-Dev-Board and with a AI-Thinker-ESP32-Cam. I use the ESP32 in AP-Mode an have to use a little bugfix in camera.c for the reset-->

    ESP_LOGD(TAG, "Resetting camera");
    gpio_config_t conf = { 0 };
    conf.pin_bit_mask = 1LL << config->pin_reset;
    conf.mode = GPIO_MODE_OUTPUT;
    gpio_config(&conf);

    gpio_set_level(config->pin_reset, 0);
    delay(10);
    gpio_set_level(config->pin_reset, 1);
    delay(10);

    //BUGFIX
    uint8_t buf[] = {0xff, 0x01};
    twi_writeTo(0x30, buf, 2, true);

Could you eventually find a solution to your problem? I’m facing the exact same issue and I couldn’t find any solution at the moment...
