Possible causes of speaker problems or poor quality sound on the iPhone 7 Plus

There are only two possibilities as to why your iPhone 7 Plus speaker is not working as intended. It could be isolated to an audio application that is glitching or symptom of hardware damage. Consider yourself lucky if the problem is software-related for you still have a chance of getting the problem fixed without having to pay extra for service or replacement of damaged components.

You can say that the problem is most likely isolated to a software glitch if it happens only when using certain applications and that there were no previous instances of dropping or liquid exposure on the iPhone. An example of this is having no sound coming when using certain audio app on the iPhone.

It could be that the iPhone speaker is working and the audio app is not. Try to use other audio apps and see if you can hear sound from your iPhone speaker when using other apps. If so, then the previous app is to blame not the iPhone speaker.

There are also other cases in which incorrect audio settings are causing the same problem. Some people for example, have failed to check that the volume level is set to the lowest level or the iPhone is set to silent mode, thus no sound is produced.

Meanwhile, common symptoms of hardware damage affecting the iPhone 7 Plus speaker would include popping noises, random stops, and no sound at all. These symptoms may appear later than sooner, especially with liquid damage. Unfortunately, your only option for hardware-related problems on your iPhone is a tech service.

Unless of course you’ve got the knowledge, skills, tools and guts to dismantle your iPhone, locate the damaged part, and fix it by yourself. Nevertheless, it is still safer to take your iPhone to an authorized service center for proper hardware assessment and if necessary, repair.

Time Needed : 15 minutes

The following workarounds will only work if there is no physical or liquid damage present on any of the iPhone's audio components. Should you wish to proceed and troubleshoot the problem on your end with the following solutions, be sure to test your device afterwards to see if the problem has already been resolved. Otherwise, proceed to the next applicable solutions.

  1. Check the Ringer switch.

    To avoid wasting time doing unnecessary troubleshooting procedures, check your iPhone's ringer switch and make sure that it is not set to silent mode. Do so if you hear no sound from your iPhone speaker for incoming calls or from other audio functions.

    The ringer switch is located on the top left edge of your iPhone. Try to flip the Ringer switch to turn Silent mode on and then off. If it's set to silent mode, the sound is off, and the switch is in red position.
    In case the switch appears to be stuck, try to remove the case to make sure that the switch is not blocked.

  2. Check and ensure no dirt, dust or debris on the iPhone speaker.

    Dirt, dust and debris can also affect the overall quality of your iPhone's audio output especially if this tends to block or clogged in the speaker. Distant sound or audio cut-offs are among the usual symptoms. If necessary, clean the speaker ports.

  3. Perform a soft reset on your iPhone 7 Plus.

    If this is the first time that your iPhone speaker is not working properly, it is a possible indication of random software glitch, particularly transpiring on the current audio app in use. To rectify these glitches, all you have to do is reboot or soft reset your iPhone 7 Plus.

    Not only that a soft reset eliminates glitches, it also helps free up some space of your iPhone's internal memory by deleting cache files.

    Here's how a soft reset is properly done on your iPhone 7 Plus: Press and hold the Sleep/Wake button for at least 10 seconds until the red slider appears. Drag the slider to power off the iPhone completely. Wait for 30 seconds. After 30 seconds, press and hold the Sleep/Wake button again until the Apple logo appears.

    Check your iPhone speaker after the reboot to see if it’s already working properly.

  4. Adjust volume settings.

    For problems on distant sound, very low sound, or no sound out all, it is possible that the volume is set to the lowest level or the ringer for sound alerts is set to mute. To make sure this is not causing your trouble, check the volume settings and make some adjustments. Try to increase the volume or set to your preferred loudness and see if there are any changes.

    To access and manage audio settings on your iPhone 7 Plus, go to Settings-> Sounds-> Ringer and Alerts and then adjust the volume level to a higher level by dragging the slider.

  5. Verify and ensure Bluetooth is disabled.

    When Bluetooth is enabled, it is possible that your iPhone is not paired to another Bluetooth-enabled audio device like Bluetooth speaker thus you hear no sound coming from your iPhone. In this case, the iPhone speaker is working but not in use at the moment. To rule this out from the possible causes, try to disable Bluetooth on your iPhone 7 Plus and then test the speaker if it's already working as intended.

    To do so, head over to Settings-> Bluetooth and then toggle the switch to turn the feature off.

    Reboot your iPhone after disabling Bluetooth to ensure recent changes are properly implemented. Check the speaker afterwards.

  6. Reset all settings on your iPhone 7 Plus.

    Should the speaker problem you are dealing with has something to do with incorrect settings that you couldn't determine, resetting all settings on your iPhone might be the key to resolving the underlying cause. However, all your personal settings and customized options will be deleted in the process.

    If you wish to take your chances and give it a try, here's how it's done: Go to Settings > General > Reset All Settings. If prompted, enter the correct passcode for your device to proceed.

    Wait until the settings reset process is finished. Reboot your iPhone 7 Plus one more time and then check and see if the speaker is already working fine.

  7. Update iOS.

    If you haven't installed the latest iOS version for your iPhone 7 Plus, then you should consider doing it now.

    A notification will show if an update is available. Before you proceed with the iOS update download and installation, backup your iPhone for safekeeping.

  8. Factory reset.

    This should be considered as your last resort when dealing with speaker problems that are software-related. All your data and information will be erased in the process and then your iPhone restores to factory defaults. Any bug residing within the iPhone's system layer that couldn't be rid by other minor process will likewise be removed.

    Should you wish to proceed with a factory reset, make sure to back up your important files beforehand via iTunes or iCloud. Once ready, head over to Settings->General-> Reset-> Erase All Content and Settings. Tap the option to Erase iPhone. If prompted, enter the correct passcode for your device to proceed.
