What should I do if the mobile phone fails to project the screen wirelessly to the TV?

If the wireless screen projection of mobile phone to TV fails, you can try it in turn according to the following solutions.

Turn on the DLNA maintenance switch.

TVs of Hisense, Konka, LeTV and other brands all have multi-screen service switches, which need to be turned on (if you can't find this switch, please consult the TV manufacturer how to turn on the service switch).

Check the screen projection mode.

If the TV uses DLNA screen projection method, this method only supports the screen projection of Huawei music (not supported by Huawei Music MV), galleries and videos (including video Youku and Huawei video), and other third-party applications do not support screen projection.

Restart equipment

Restart the TV, box and router. Close the video application, and then open it again to ensure that the phone and TV are connected to the same WiFi.

Clear cache

Open the settings, search and enter "application management", click three buttons > show system flow, and find the wireless projection screen (multi-screen interaction); Click Save? & gt？ Clear the cache? & gt？ Delete data.

Check whether WLAN+ is turned on.

When turned on, it may affect the use of the screen projection function. Please drop down the phone interface and search for "WLAN+" in the search box to turn off this function. Tip: WLAN+ function may cause two terminals to connect to networks that do not belong to the same LAN, and this function will give priority to the best WLAN.

Restore network settings

Open it? Settings, search for "Restore network settings" in the search bar, and click? Restore network settings. Tip: Restoring network settings will erase WLAN, mobile network data and Bluetooth data. If the problem still cannot be solved, please back up the data in advance (WeChat /QQ and other applications need to be backed up separately) and bring the purchase voucher to Huawei customer service center for testing.
