A. 1. Check your internet connection: Ensure you have a stable Wi-Fi or mobile data connection. Try switching between Wi-Fi and mobile data to see if the issue persists. 2. Restart your router: If using Wi-Fi, unplug your router for 10 seconds and plug it back in. 3. Reset network settings: Go to 'Settings' > 'System' > 'Reset options' > 'Reset Wi-Fi, mobile & Bluetooth'.
B. 4. Disable battery saver mode: Go to 'Settings' > 'Battery' and ensure battery saver mode is off, as it can limit background data.
