@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.

@MrT10001 waiting your good news

@MrT10001 thanks your response, when charging and I plug the USB storage into the OTG HUB,it is not work. and when reading USB storage then plug the charger, USB storage will remove automatically. I don't know if anyone have encounter this issue, please share you experience, thanks!

appreciate if anyone can help,thanks!

1+6T can not read USB and charging together when use OTG USB HUB, that is the known issue or can fix it?

@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

@MrT10001 thanks your response, I know how to reset the partitions, but what I want that create the swap and increase the memory, I am not sure if can work in UT.

@Moem increate the memory for run the script, is that possible? or some limit in ubuntu touch?

when use command free -h show the memory , it show Swap value is 0, how I can create the Swap and use it? anyone have the detail step? thanks!

@arubislander ok, Thanks for your answer.
