• Poor Call Quality/Bluetooth Issues: Check network signal strength. For Bluetooth, ensure the device is paired correctly and within range. If issues persist, try restarting the phone or resetting network settings.
• Battery Draining Quickly: Close unused applications, reduce screen brightness, and disable unnecessary features like Wi-Fi, Bluetooth, or GPS when not in use. Check battery usage in settings to identify power-hungry apps.
• Apps Crashing/Slow Performance: Clear app cache (Settings > Apps > [App Name] > Storage > Clear Cache). If the issue persists, consider uninstalling and reinstalling the app. For overall slow performance, free up storage space or perform a factory reset (back up data first).
