A：1. Unstable network or insufficient network speed: Please check if your mobile network signal is stable and test if the network speed matches the video resolution. Slow network speed or unstable signal can cause video playback to stutter. You can try switching to a different network or lowering the resolution of the video.
2. During peak user usage times, the video provider's server is also under pressure. If the number of users at the same time exceeds the server's maximum capacity, video transmission will be very slow, causing stuttering. It is recommended to try a different video client to verify the video provider's server issues.
3. Insufficient system resources: If too many programs are running in the background, it can lead to insufficient cache space for videos or insufficient system computing power, causing stuttering or even playback stoppage. It is recommended to close unnecessary background programs and clear the cache or delete useless files to free up more memory space.
