1. Press and hold the application icon on the mobile phone desktop, click enter application information, and then restart the mobile phone to use.
2. When playing network video and live broadcast, the requirements for network signals are higher. I suggest you change to a good data network or a wireless network with strong connectivity.
3. If you use a three-party player to play videos that are not cached by yourself, you can install other apps of the same type and restart your mobile phone to play them again.
4. Check whether the mobile phone supports playing video format. If not, try a different player.
5. Clean up the background application with one click and upgrade the mobile phone system to the latest attempt.
Tips: You can enter "product name+video format" to inquire about the video format supported by the mobile phone, such as the video format supported by Reno4.
