Thanks for your post and welcome to the TeamViewer Community.
Maybe you would like to give our TeamViewer Host for Android a try. The TeamViewer Host app allows you to remotely control unattended Android devices. A connection is therefore possible even when the device is not being actively used.
You can find a link for the download here: https://www.teamviewer.com/en/download/android/
You can even mass deploy it.
I hope the info helps you.
All the best, Esther
