Hi there LTH,Thanks for posting.In regards to remote controlling of your Jiayu S3+ device, it is most likely that these devices may not support the remote controlling (controlled) function.This is the case for a few other Android devices where connections and viewing of the screens are possible but the function of being controlled is limited.Please view the following article in regards to TeamViewer supported devices. https://community.teamviewer.com/t5/Knowledge-Base/Supported-manufacturers-for-remotely-controlling-Android-devices/ta-p/4730Thank you once again for posting.Yuhi
