Why is the connection between Samsung mobile phone and Huawei mobile phone worse than wifi signal?

If the mobile phone's WIFI signal is weak or unstable, resulting in frequent disconnection, suggestions: 1. Check whether other devices are connected to the wireless network and the signal is good or complete. 2. Check whether there are many devices connected to the wireless network. 3. Restart the phone and search for the WiFi signal again. 4. If it is a home router, it is recommended to disconnect the power supply for a period of time and try again. 5. If you use the wireless network of the network operator, it is recommended to try to change the location. 6. Try to change another wireless network. 7. Back up the data in the machine (such as contacts, short messages, multimedia, etc.). ), and then restore the factory settings. If the problem still exists after the above operation, please take the purchase invoice, maintenance card and machine to Samsung service center for inspection.
