The Nubia Z17 phone by ZTE comes enabled with Miracast technology allowing its display to be wirelessly mirrored onto a compatible TV like the Sony Bravia 4K Ultra HD Smart LED TV with Android easily.
Under the phone's Settings, start Miracast on the Nubia Z17 by selecting More Connection Methods -> Screen Projection. At the same time, check that your local WI-FI network is already enabled.
Select the 'Project to TV' option and the Nubia Z17 will start to detect any Miracast-supported displays nearby. You should see the Sony Bravia 4K Ultra HD Smart LED TV with Android as 'KD-55X8500C', which when selected the screen mirroring connection process will begin.
Once successful, the Nubia Z17 will immediately get connected to the TV, and the phone's screen will be displayed.
The Nubia Z17 can connect well with the Sony Bravia 4K Ultra HD Smart LED TV with Android using Miracast but not recommended for long sessions of high resolution fast motion video or gameplay.
