Why is the phone not turning on?
First, check if the battery is charged. Press and hold the power button for at least 5-10 seconds. If still off, try removing and reinserting the battery. If the issue persists, the battery may need replacement.
How do I adjust the volume and ringtone?
Use the side volume keys during a call or in standby to adjust the earpiece and ringtone volume. For ringtone settings, go to Menu > Settings > Sound Profiles, choose a profile, and select the desired ringtone from the list.
How to use the FM radio without earphones?
The FM radio requires earphones to act as an antenna. Plug in the earphones, then go to Menu > FM Radio. Press Play to listen. The radio will work through the speakerphone even if earphones are used as antenna.
Why can't I hear the caller or they can't hear me?
Check the volume: press the side volume keys to increase. Ensure the microphone is not blocked by a case or debris. If using a headset, ensure it's properly connected. If the issue persists, reboot the phone.
