@Luksus As you are the maintainer I take the opportunity to ask you the question, will the tablet on UT be compatible with Waydroid ?

@luksus great, I was able to install /e/OS (android 10), it seems to work well, but I have not yet tested everything, well it's not Ubuntu Touch but it is better than nothing

Thank you for the time you took to help me, I think I will send it back because I did not find any other alternative to install on the tablet, do you know if we can install another OS?

and today:

@luksus I tried with the older version of android but it didn't help.
I remembered that I made a screenshot of an error when I installed android and I had the same error today, I don't think it will help my problem but I put the screenshots:

@luksus said in unknown battery level:

So your overall setup looks ok to me.

For you it would be the battery that is at fault? even if on android it works

The battery is charging from the command output, but probably very slowly because for UT it's at 100% but the battery icon is green, so it's finishing charging (like on my OPO) that's why the charger doesn't heat up, but at this speed it's going to take me a few days to fully charge it, but not sure if UT is seeing the real full charge either

If I redo the command with the charger plugged in, could it help you?

@luksus yes it doesn't communicate properly with UT, and it doesn't seem to be charging with UT either, it's strange

@luksus said in unknown battery level:

Did you check the "bootstrap" option in the installer?

yes, it was checked

@luksus said in unknown battery level:

was the power adapter plugged in, while executing the upower command?

No

@luksus said in unknown battery level:

Which channel did you install ( devel,rc) ?

Devel
