Sometimes, we want to be able to control another mobile device through our mobile phone. For example:
At home, sit on the sofa and use your mobile phone to connect to the Android smart TV. You can see the complete picture of the TV and operate it;
Sit in the back seat of the car and connect to the car's Android panel to play music, videos, or adjust the volume. It may also help the person driving the car set the navigation.
In fact, there are already some similar applications, but unlike what we call "control/remote control" now, most of the current applications are the opposite. For example:
Transfer pictures or selected YouTube videos on your phone to your Android smart TV. Sounds great! But what often happens is that the mobile phone becomes extremely slow and seems to be crashing, or there is nothing on the TV after clicking to transfer the video for a long time, because transferring the video consumes too many resources. If you connect to a TV and open YouTube on the TV to play the video, it will be much faster, because the video itself is opened on the TV, and there is no need to transmit the video and sound through the mobile phone.
There are many similar eritrea leads ones for cars. At present, most of them use the user's mobile phone to transmit music, navigation, etc. to the Android panel in the car, and then the Android panel in the car plays it. This is also good! However, most of them currently require the purchase of additional connecting cables. Most of the connecting cables only have one, and can only be controlled by one person at a time. If you sit in the back seat and in different positions, the length of the connecting cable is also a problem.
