@MrT10001 oh, cool, that is the good news, thanks your research,so the solution that I need change the more better OTG hub, I will try it, thanks your effort again.
@ikoz I search in internet and find below solution, but not work, even memory fully used, but swap used still is 0, I don't know why.
sudo fallocate -l 8G /userdata/swapfile
sudo chmod 600 /userdata/swapfile
sudo mkswap /userdata/swapfile
sudo swapon /userdata/swapfile
sudo sysctl vm.swappiness=80
