iPhone 11 Pro Max 4G LTE Signal Issue
The new iPhone 11 Pro Max loses 4G signal from time to time (every a few minutes) when the Wi-Fi is off or no valid Wi-Fi hot spot is nearby.
Wi-Fi is off: The 4G signal drops to null in a sudden, and restores to full (4 bars) in 2-3 seconds. This happens regularly.
Wi-Fi is connected: The bars are steady - stay at 4 all the time.
I have tried:
- Disable Auto Network Selection
- Reset Network Settings
- Reset All Settings
- Reset All Content and Settings
None of them shows promising improvement.
