Why does my Android phone volume keep turning itself up?

It can be frustrating to have an Android phone’s volume randomly start turning up on its own. It’s disruptive if it happens during phone calls or while listening to media. Worse, it may lead to missed calls or messages if the volume gets turned down without your knowledge.

There are several potential causes for an Android phone’s volume to change automatically. This article examines the most common reasons you may experience this problem on your device.

Software Issue

A software bug or glitch in the Android operating system can sometimes cause the volume to spontaneously increase or decrease on its own. As explained on this Reddit thread, some Pixel users have experienced an issue where the volume gets set to 75% randomly after having set it to max volume on the speakers. This appears to be an actual software bug that Google may need to address in a future OS update.

Bugs like this can occur when there is a problem with the system code that handles volume controls. It may inadvertently trigger volume changes without any user input. While the exact technical details behind this are complex, the outcome is that the volume starts changing up and down on its own until the bug is fixed.

If you believe your issue stems from a software bug, try updating to the latest Android OS version available for your device. You can also search online to see if other users of your phone model have experienced similar problems – that’s a clue that a bug could be the culprit.

Physical Damage

Physical damage to the volume buttons, headphone jack, or other hardware components related to audio can cause issues with volume control on Android phones. If the volume buttons get stuck in a pressed-in position or are otherwise damaged, it may cause the volume level to automatically go up or down without the user intending it to.

For example, if the volume up button gets jammed or broken in a way that it’s constantly activated, it will keep turning the volume up even if you don’t press it. Similarly, damage around the headphone jack like a loose connector could cause it to randomly switch between the phone speaker and headphones, resulting in unexpected volume jumps.

Dropping your phone or otherwise impacting it can knock components loose or break mechanical buttons and switches. Over time, regular use can also wear out the spring mechanism under the volume and power buttons.

Inspect your device for any visible damage like dents, cracks, or rattles that may indicate a dislodged component. Try cleaning around the buttons and headphone jack with compressed air to remove any debris or dust buildup. If an issue persists, you may need professional repair to replace damaged hardware like the volume flex cable or headphone jack module (source).


Liquid damage can easily activate the volume controls on an Android phone. As this YouTube video explains, the volume buttons and other components on a phone’s logic board are very sensitive to moisture and liquids. If any amount of water gets onto these parts, it can start closing circuits and activating functions randomly.

Moisture bridging between contacts on the logic board is very likely the culprit when the volume keeps changing itself. Water damage essentially starts “pressing the buttons” for you by closing circuits where it shouldn’t. Gravity can make this water travel deeper into the phone over time as well, leading to more erratic behavior from the volume controls (wikiHow).

According to members of Android Central’s support forums, one sign of potential water damage causing issues like unwanted volume changes is the volume buttons physically sticking when pressed (source). So if the volume keys get “stuck” even once, moisture intrusion could already be present inside the phone and causing electrical problems.

Proximity Sensor

The proximity sensor on Android phones detects when an object, such as your hand or face, is near the screen. It uses this to trigger various functions like turning off the display when you hold the phone to your ear during a call. However, issues with the proximity sensor can inadvertently increase the volume when covered.

Specifically, when placing your hand over the top part of an Android phone where the proximity sensor is located, it can trigger the phone to switch from using the earpiece speaker for audio to the loudspeaker. This will make any music, videos, or calls suddenly get much louder. The phone is trying to optimize the audio experience for speakerphone mode rather than private listening.1

Fixing proximity sensor issues requires troubleshooting to determine if it’s a hardware or software problem. Cleaning the area around the sensor, rebooting your device, or adjusting sensor sensitivity in settings may help. If problems persist, a repair or replacement may be needed.

Accessibility Setting

An accessibility feature like “Touch with vibration” could inadvertently cause volume spikes on an Android phone. This setting provides haptic feedback in the form of device vibrations to confirm touch interactions (1). However, the vibration motor can sometimes emit an audible clicking sound that the phone may interpret as an attempt to raise volume.

The Accessibility Menu offers various options to assist users with disabilities, such as text-to-speech, magnification, and hearing aids (2). If “Touch with vibration” is enabled, each tap triggers haptic feedback. But the vibration motor may not be properly secured or muffled, allowing it to make noise. The phone’s microphone can detect these sounds and wrongly increase the volume in response.

To prevent this, try disabling “Touch with vibration” in the Accessibility Menu. Also inspect the phone casing to ensure the vibration motor is properly installed without loose parts. Using a sturdy case can help block motor sounds. If issues persist, restoring default settings or performing a factory reset may be necessary.

Third Party App

One possible cause of the volume turning up automatically is a third party app causing interference or making unintended changes to the volume settings. App functionality with accessibility controls or media playback features can sometimes result in system-level volume adjustments.

For example, an accessibility app that reads text aloud may turn up media volume to make speech more audible. A music or video streaming app may also increase volume between tracks or videos to maintain a consistent loudness. Even apps without obvious media features can potentially alter volume if they have been granted accessibility permissions.

As this Reddit thread mentions, using a third party app called Sound Assistant can help troubleshoot by providing individual volume control per app. This could reveal if a particular app exhibits abnormal volume behavior compared to others.

Checking installed apps and their associated permissions can determine if any unnecessary programs have access that allows interfering with volume. Revoking certain accessibility permissions from suspect apps is worth trying to rule out third party interference as the culprit.

Other Causes

While less likely, there are a few other possibilities that could potentially cause your Android phone’s volume to increase on its own.

If you are using wired headphones, it’s possible there could be a short circuit causing them to send errant signals to your phone to raise the volume. Try using your phone’s speakers or different headphones to see if the issue persists.

In rare cases, a faulty power button could also be sending accidental volume-up signals. You can test this by locking your phone and seeing if the volume still goes up without any button presses. If so, you may need to get your power button replaced.

Older phones may also have some degradation or dust buildup internally that could cause contacts to short and raise the volume. While unusual, a deep clean or replacement of internal hardware could potentially resolve it.

Finally, some third party cases or accessories clasping onto the phone could potentially depress buttons. Remove your case and any plugged in accessories to rule out interference from external hardware.


If your Android volume seems to be automatically increasing and decreasing, there are some troubleshooting tips you can try to address the issue:

Restart your phone
A basic step is to turn your phone off completely, wait a few seconds, then power it back on. Restarting can clear any minor software glitches affecting the volume.

Boot in Safe Mode
Boot your Android into safe mode, which will disable third-party apps. If the volume behaves normally in safe mode, a third-party app may be causing the issue. You can then begin uninstalling recently downloaded apps one-by-one to isolate the problem app. Re-install apps you want to keep to rule them out.

Factory Reset
If other troubleshooting fails, performing a factory reset can restore your Android software and settings completely back to default. This will erase your phone data, but should also erase any deeper glitches affecting the automatic volume changes.

Following these troubleshooting tips should help resolve most cases of Android volume increasing/decreasing automatically without input. If issues continue after a factory reset, a hardware problem with your volume controls could be to blame instead, in which case you’ll likely need to replace the device.


The sudden and unexplained increase in volume on Android phones is usually caused by a software glitch, physical damage, moisture interference, the proximity sensor being triggered, an accessibility setting being enabled, a third party app, or in rare cases, another unknown issue. The solutions include restarting the phone, adjusting accessibility settings, deleting problematic apps, inspecting the phone for any physical damage, and getting the phone serviced if the issue persists.

The most common causes are software and hardware issues, malfunctioning proximity sensors, and accidental enabling of accessibility services. Most instances can be reliably resolved by users at home by methods like restoring factory settings, removing apps or cases, or fixing physical damage. But in some situations, professional repair may be needed to diagnose and correct a less common underlying issue. The key is to apply troubleshooting steps methodically to identify the specific problem for that device. With persistence, spontaneous volume spikes can typically be successfully stopped.
