Hi there! I understand that after updating the WordReference app, your phone's network setting changed to "Prefer LTE," and now you no longer see the 4G option. Let's get this sorted out together.

First, just to clarify: Is the issue only occurring after the app update, or have you noticed this network option change elsewhere on your phone? Also, can you tell me the exact make and model of your phone and the version of Linux or Android it's running?

In the meantime, here’s a simple checklist to troubleshoot this issue:

1. Check Mobile Network Settings:
- Go to your phone's Settings > Network & Internet or Connections > Mobile Network.
- Look for Preferred network type or Network mode. You might see options like "3G/4G/5G auto," "LTE only," or "Prefer LTE."
- Sometimes, the “Prefer LTE” setting acts similarly to 4G, but the label might just be different now because of software changes.

2. More Network Settings or Advanced Options:
- On some devices, under Mobile Network, there’s a section named More Network Settings or Advanced Settings. Try opening it to see if the 4G option is inside an extended menu.
- This appears to have helped others getting deeper network options after an update1.

3. Reset Network Settings:
- If you don’t find the 4G option or the settings seem limited, try resetting your network settings:
Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth. This resets network configs without deleting your media.
- After resetting, check again for the 4G/ LTE option.

4. Check for Carrier or System Updates:
- Sometimes, carrier settings or system updates affect available network modes. Double-check if you have any pending updates in Settings > System updates.

5. Reinstall the WordReference App:
- Though unlikely, the app update affecting network choices isn't common. You can try uninstalling and reinstalling the WordReference app to see if that changes anything.

If after these steps you still don't see 4G explicitly, it might be that the OS or phone manufacturer is using "Prefer LTE" as the official label, which is essentially the same as 4G LTE. Would you like help verifying if your current connection is 4G LTE even though it says "Prefer LTE"?

Let me know, and we can dive deeper or try alternative steps based on your phone type and OS version!
