Having or not root access is not a X9S problem. The most of android devices is not rooted. Selling X9S as is originally is not a X9S or Zidoo issue. Anyway I also like to have root access to my X9S. But also like to have to choose to have a really unrooted X9S (for apps that don't "like" rooted devices), or have a finely roooted X9S, to have complete control on it. And also to change to one condition to the other and back, if I like to. Precisation: not "I like", but ""I want"... if possible
On X6 pro Teamviewer QS works only if you install the Zidoo version. Any update to more recent release don't work any more. Problem depends on deep integration of any Teamviewer app with each single HW. Teamviewer don't spend time to develope a specific version for Zidoo, there was one release for X6 Pro, and AFAIK Zidoo is working with Teamviewer for a release also for X9S. Seems not so easy, so be patient. Zidoo, is this correct?
teamviewer host reports the box supports remote controll. but when it promts you to install the plugin, it fails. Still you can connect to the box, see some info. But the remote control part needs fixing
Get the quick support app. Then get the teamviewer host app. When you get the host app it will ask to download a addon for remote viewing. Get it. After it downloads open quick support and it should work.
