What should I do when I flash back when I open the nail

1. The black screen of the mobile phone may be caused by too much data stored by nails. You can find more settings in Settings, then click More Applications to find nails in more applications, and then click Clear Data.

2. If there is a black screen when the user watches the live broadcast with nails, check whether the nail version is below 5.0. If it is necessary to update the nail to the latest version, if it is still blank, try to uninstall the nail and reinstall it.

3. If the user has a black screen when using the nail live broadcast, it may be the reason why the user network is not good. You can try to switch networks or check whether the equipment meets the requirements.

If the nail flashes back during use, it may be that the software cache is too large to run normally, so it is recommended to clear the software cache. It may also be that there are too many applications in the background of the mobile phone, which leads to insufficient memory in the mobile phone when the nail is opened, resulting in flashback. If this is the case, the mobile phone needs cleaning. You can also uninstall the software, reinstall it or change it to another software version, and then try to see if it can be opened normally.
