I’m using three Android Tablets (Asus ZenPad 10) running Fully Kiosk Browser showing HabPanel.
The Asus Tablets are running on Android 7, of course heavily branded by Asus, but I tried to remove all unnecessary stuff as good as possible. The only App running is Fully Kiosk Browser, which runs with all privileges showing my HabPanel. (the same panels on all tablets). HAB Panel has 14 dashboards. My FullyKioskBrowsers are integrated in my OpenHAB (Version 2.4) and I can monitor and Control them/it (Screen On/OFF, Battery, REload, etc.)
That’s basically working quite fine. BUT:
after some minutes of inactivity habpanel gets really slow on the tablets. I found to ways to workaround this:
- If I reload the page it starts to perform good as well, but I have to wait these reload seconds.
- If I switch between the dashboards for some seconds it starts to become more responsive again.
However, in any case, I have wait some time until i can use it.
I assumed, and somehow still assume, that it has something to do with the power management of the android device. It seems like the tablet goes in some kind of power save mode with dramatically reduces the power and needs to wake up after some seconds. Turning off all these features, setting CPU Wakelocks, etc. didn’t help so far.
I already looked into it via the developer console, but connected via a USB I was not really able to reproduce the issue.
has anyone else experienced something similar and/or has anyone any ideas to fix this?
