My Galaxy Z Flip 4 has a weird issue where it will connect to my home WiFi fine, but will only work in some apps. Mobile data works fine in all apps, but WiFi doesn't work, specifically in Twitter and most Google services, like Translate. I have tried everything that @Vaotix tried in his post about what seems to be the same issue, including the Samsung solution, with the only difference being that they have a Fold 4 and I have a Flip 4.
Hello @razorrr, We understand how frustrating it is when apps are not working over Wi-Fi. Just to be thorough, the troubleshooting you've tried so far includes:
Enable and disable airplane mode
Deleted my WiFi network on my phone and reconnected to it
Reset Connection and Network settings on the phone
Rebooted the phone
Reset/power cycle my router and modem
Tried turning off some intelligent WiFi features
Made sure my phone is on the latest firmware version and that Google Play Services is up to date
Updated all apps on my phone
Cleared the cache of apps that wouldn't work on WiFi
Cleared cache partition and repaired apps
Another step we recommend is restarting the router by unplugging it for a few minutes.
Try testing the apps on another Wi-Fi network to rule out there being a setting in your network settings blocking the apps.
If the apps will still not work, we recommend having the phone evaluated by a certified technician.
