Volume issues on the iPhone are resolved by adjusting the physical or virtual buttons and switches upon the mobile device. Volume issues on the iPhone affecting ringtones, text messages (also known as SMS), voice mail, email, calendar alerts or miscellaneous sounds (like iPhone keyboard clicks) are resolved using the Settings app.
Volume issues affecting third party applications are resolved within the respective apps themselves or by contacting the developer or creator of the iPhone app.
Troubleshooting Basic Volume Issues
Locate the long physical silver button on the side of your iPhone. Push upon the top portion (which is located underneath the vibrator toggle switch). The "ringer" status will appear on your iPhone screen. Continue pushing upon the silver button until all 16 white boxes appear.
Locate and tap upon the Settings app with your finger. If you are unable to find the settings app, tap on the physical home screen button once, then after two seconds tap on it again. Type in "Settings" in the search field, then tap on the option with your finger.
Tap on the "Sounds" menu option with your finger, and underneath the "Ring" section, tap on the volume control circle with your finger (located underneath "Vibrate" and above "Ringtone") and slide it to your left, which will play your default ringtone sound (verifying that the sound is functional on your iPhone).
Troubleshooting Ringtone Volume Issues
Locate the small silver switch (which is above the long silver button) and verify that you do not see a small orange dot (which means your iPhone is on vibrate). If you see a small orange dot, push or move the switch (to make the orange dot disappear), then verify that you see a bell icon appear on your iPhone screen.
Then tap on the "Settings" app with your finger and locate as well as tap upon the "Sounds" menu option. Tap on the volume control circle, which will play your default ringtone.
If you are unable to hear a ringtone, tap on the "Ringtone" menu option and tap on one of the default ringtone sounds (such as "Blues," "Alarm" or "Scifi") which will play the specified ringtone sound.
Troubleshooting Text Messaging Sounds
Locate and tap upon the "Settings" app with your finger, then tap on the "Sounds" menu option. Tap on the "New Text Message" menu option with your finger, then verify that the "None" option is not checked.
If "None" is checked, simply tap on another option (such as "Horn" or "Electronic") which will play the text message sound on your iPhone. Tap on the "Sounds" button near the top of the iPhone screen to confirm your text message sound alert.
Troubleshooting Miscellaneous Volume Issues
Locate and tap upon the "Settings" app with your finger, and then tap on the "Sounds" menu option. Scroll down to the "Ring" section, and locate the buttons next to "New Voicemail," "New Mail," "Sent Mail," "Calendar Alerts," "Lock Sounds" and "Keyboard Clicks."
Verify that all of the buttons are turned on by tapping on them with your finger, which will play a sound to confirm that these miscellaneous features are functioning properly.
Troubleshooting Volume Issues In Third Party Apps
Locate and tap upon the "Settings" app, then scroll down until you locate the specific application. Tap on the application with your finger, then locate the specific volume settings and adjust accordingly. You may have to open up the iPhone app to troubleshoot problems regarding the respective app.
To troubleshoot volume issues for push notifications, return to the main "Settings" screen and locate "Notifications" (near the top of the screen) and tap on the menu option with your finger.Tap on the specific app you are experiencing problems with, and then tap on the button next to the "Sounds" option and verify that it is displaying a blue "On" status.
You will hear a sound the next time you receive a push notification from that specific iPhone app.
