Sometimes no boot from SD

Hi All,
I have an X96 pro plus with coreelec on SD card.
Sometimes (specially when I unplug and plug the power cable) the box boots with Android and not with coreelec.
It is random and sometimes I solve it restarting the box, sometimes I have to remove and insert again the SD.
Any suggestion on how to solve this problem?

Regards

You could see if the problem persists with another SD Card.

Some boxes seem a little finnicky with regard to power demands on the USB ports. I have an older X96 box which reverts to booting in Android if there are multiple devices on the USB ports eg. a hub with mouse and keyboard and/or certain USB sticks of an older generation. Try booting with nothing plugged in the USB ports.
