Frequently Asked Questions (FAQ)
Is it possible to transfer an image if the phone screen is off?
When using Smart View or screen mirroring, turning off your phone's screen usually interrupts the stream, or the TV screen also turns off to save power. However, when using Google Cast or DLNA (via YouTube and similar apps), the phone only acts as a remote, and you can turn off the screen while the video continues playing on the TV.
Why doesn't my Samsung A02 see my TV in the list of devices?
The most common cause is that the devices are connected to different networks (for example, one to a guest network and the other to the main network). Also, check if "AP Isolation" mode is enabled on the router, which prevents devices within the network from seeing each other.
Does image transmission affect internet speed?
Yes, streaming high-quality video consumes a significant amount of WiFi bandwidth. If you watch 4K video on your TV via your phone, page loading speeds on other devices on the same network may temporarily decrease.
Do you need internet access to transfer photos via WiFi?
To transfer photos and videos stored locally on your phone, you don't need internet access. Both devices only need to be connected to the same router, even if the ISP cable is disconnected from the router itself.
