There could be a number of reasons for the Meizu 17 network instability. First, there may be a BUG in the app store that prevents you from connecting to the network. In addition, the sudden loss of dual card signal is also a problem, even if set to 4G is relatively stable, but still can not completely solve the problem of sudden loss of signal. It is also possible that the third-party management, security, and anti-virus software in the mobile phone conflicts with the system, resulting in network instability.
Here are some possible solutions:
1. Reinstall your own app store or download other download software to download the app.
2. Reconnect to the network WiFi or use data.
3. Uninstall the third-party management software, security software, and antivirus software, and restart the mobile phone.
4. If the above methods cannot solve the problem, it is recommended to contact Meizu official customer service or go to Meizu official after-sales service center for maintenance and consultation.
This is generally the reason for your network signal, and the phone itself is not really related.
Turn the network back on once it's turned off, or try rebooting your phone
