Today, mobiles are capable of playing all kinds of multimedia content. Although, on many occasions, what we really like is the fact of watching videos or movies on a somewhat larger screen without having to leave our eyes. Also, this is a good way to save battery life. But, to achieve this, we will have to do it wirelessly on a compatible device.
However, the tool to send or share the screen may fail. And it is that, when we want to connect two devices wirelessly, there are many factors to take into account. Also, we must not forget that they must be connected to the same network and that the relationship between hardware/software must work perfectly to avoid surprises.
The problem is that the fact of transmitting content from our mobile to another screen does not always work without errors. Although, luckily for us, we have several solutions to solve it.
Causes of the problem
As much as we try over and over again to connect or transmit what we see on the phone panel to the TV, if there is no good Wi-Fi signal in our house it will be impossible. In most cases, not only will it take time to connect, but the image will be blurred, with worse audio and even the content will be frozen.
One of the most common errors is that the router is too far from where we want to carry out this action with our phone. However, it is not the only error that we will have to face when trying to transmit the mobile panel on television. We know that apps like YouTube or Netflix allow content to be sent to other connected displays, but there are still many applications that do not allow this type of connection . Therefore, we must check if the wireless connection icon appears at the top of the application. If not, it is possible that it is not compatible and for that reason the pairing that we wanted so much cannot be carried out.
In addition, another reason that will lead us down the path of bitterness will be that our Wi-Fi is too congested . In other words, if we are living in a building with many wireless networks, it is likely that your router is emitting a saturated radio frequency channel. So it will make it difficult to use devices with these connections. Although, we already warned you that it will not be one of the main problems. For this reason, below we will give you the main keys so that you can solve this error from your phone without it becoming a real headache and you giving up forever.
how to fix it
The action is as simple as touching on our mobile and sending the panel to TV, that is, as if we put the phone on TV. This serves both to see the screen of the smartphone duplicated on the other , and to launch the various applications that support this technology, and which are the majority of those present on the market. But, if it just doesn’t work for you, these are the different methods that you should try and that we will explain to you one by one.
Check connections
This is the first check we need to do. It is something that should be part of the initial check, but it is a large part of the cases, the truth is that the failure when trying to send content from our mobile is that we do not realize that only the mobile data network is activated. This will be the reason why the connection icon does not appear. It can happen because the Wi-Fi icon has been accidentally turned off and we are under the data network without being aware.
Therefore, we must make sure that our mobile is connected to the Wi-Fi network and that we can navigate correctly. Then we must verify the same on the TV or second screen, since both devices must be connected to the same network . If possible, we must vary the TV connection between data and cable, to rule out that this may be the problem.
Change connection mode
It is possible that the problem is in the type of connection established by our router . There may be compatibility issues, if one of the devices is connected to the 2.4 GHz network, while the other is connected to the 5 GHz network. In this case, we must make both the mobile and the external device connected to the same network standard, and try sending content again. To do this, we just have to look for the same connection and put the Wi-Fi key from the settings of both.
When Wi-Fi+ is on
The screencasting feature may be affected if this functionality is enabled. To check it we will have to enter the network settings and write Wi-Fi Plus in the search box. If we find the selector activated, we must press to deactivate it and try again. However, not all phones have this technology. So it will not be such a widespread error.
Clear app cache
This process tries to eliminate the problem, clearing the cache of the apps involved. Some of your files may have become corrupted and are negatively affecting your ability to connect. To do so we will have to go to Settings> Applications and select the app from which we cannot send the content. Then we click on ‘Clear data and cache’, restart the mobile and try again.
Reset all settings and devices
This solution involves restarting all the devices involved in the connection so that connectivity is reestablished in all of them and the function can be recovered. Therefore, we must do the following:
- Restart the router in our house.
- Close the app from which we want to transmit the content from the mobile to the TV wirelessly.
- Reset smartphone network settings: Settings > System > Reset/Reset options > Reset network settings or Reset network settings . However, it can also be within Settings > Connections. In addition, it is important that we know that we will not lose any data, but we will have to reconnect to our Wi-Fi network again.
Error with Chromecast
Another of the most common failures occurs with the Chromecast that we have connected to the television itself. And it is that, sometimes, as much as we try to transmit any type of content, it is impossible to achieve it since it continuously gives us an error.
To begin with, we must be clear that they have to be on the same Wi-Fi network, otherwise, we will not be able to send what we want to the accessory that we have on TV. In addition, the app itself, as in the previous case, must have the option to pass the content of the phone.
However, the most effective solution to fix the problem with the Chromecast is to restart it. Most of the failures will be solved by turning off the device and then turning it on the next second. So you go behind the TV, remove the micro USB power cable and plug it in after a few seconds. In this way, the Google accessory will restart and connect to Wi-Fi correctly without giving us a connection failure again. Of course, keep in mind that this process should not last more than a couple of minutes. If it’s having a hard time getting on the wireless network, you should try moving the router closer to this device so it can get a better signal.
