Why does my phone vibrate for no reason

Why does my phone vibrate for no reason: The main reasons why a smartphone can vibrate by itself?

The smartphone may vibrate for no reason, even if it does not receive notifications, messages, or incoming calls. This indicates problems that occur for various reasons. Why does the phone vibrate by itself and how to fix this problem?

Notifications not showing

Some apps can sometimes crash, causing notifications to arrive on the phone but not appear in the notification bar. At the same time, you can find out about them only if you open such an application yourself. The problem can be fixed if you update the program or enable pop-up notifications in developer mode. For this you need:

  1. Activate developer mode (in the “About phone” section, click on the line “Build number” 5-7 times).
  2. In the settings, find the section “For developers”.
  3. Activate the “Pop-up Notifications” feature.

This will force some notifications to show up, which will help you find out why the phone is vibrating. After solving the problem, the function should be disabled.

Background processes

Vibration can occur due to activities that background processes perform. To find out which applications are active in the background, you need to:

  1. Enable developer mode on your smartphone.
  2. Open the appropriate section in the settings and find the item “Background check” or “Show background processes”.

Here is a list of all applications that are running in the background. If some of them should not work, you can turn them off.

Problems with saving to external storage

In the smartphone settings, you can select a section where new information will be saved – downloaded files, applications, etc. But not on all devices, this process runs smoothly, which causes a conflict between the internal memory and external storage when trying to save any data to the phone. This can also happen without user intervention, as some information is stored offline (eg updates).

Another feature in developer mode will help fix this problem. To activate it you need:

  • Enable developer mode and open the “For Developers” section.
  • Find and enable the “Allow saving to external drives” option.

Reconnecting via Bluetooth

If Bluetooth devices (speakers, headphones, etc.) are connected to the phone, they may reconnect if the signal is poor, causing the phone to vibrate from time to time. The problem will be solved by itself if you disconnect such a device from your smartphone.

Out of memory

When the smartphone is almost out of free space, the device begins to experience problems installing new applications, updates, or programs. In this case, deleting unnecessary files will help – if there is enough free space, the smartphone will stop vibrating.

Internal damage to the smartphone

Unreasonable vibration occurs if the internal parts of the smartphone are damaged. Most often this happens due to drops or bumps, but the physical obsolescence of the phone can also affect. It will not be possible to solve such a problem on your own, since it is necessary to disassemble the device and look for the cause inside it.

Moisture ingress

Due to the ingress of moisture into the smartphone, a short circuit may occur, which will cause problems with the correct operation of the vibration motor. If the phone has been exposed to rain, dropped into water, or liquid has been spilled on it, the device should be disassembled and dried as much as possible. If the model has a non-removable cover, then it is best to take it to a service center where specialists will disassemble the smartphone and dry it completely.

Problem with newly installed app

If the smartphone began to vibrate after installing any application, it is highly likely that the problem is in it. It also happens that it is not possible to establish which application is to blame for the problem. The safe mode of the smartphone can help with this – only pre-installed programs work in it. If the vibrations disappear in safe mode, the problem lies with one of the applications installed by the user. It is necessary to remove them one by one in order to understand which one does not work correctly.

Software failure

A common cause of vibrations is a software failure of the smartphone. Usually it is temporary and is “cured” by a normal reboot. If this does not help, you need to check and, if necessary, update the phone software – you can do this through the settings.

Clearing the system cache can also help:

  1. Disable phone.
  2. Hold down the keys to go to Recovery. On most models, you need to hold down the “Enable” and “Volume Up” buttons to do this.
  3. Using the volume keys, select the item Wipe cache partition.
  4. After the procedure is completed, click on Reboot system now.

These actions do not delete data from the phone, but only clear its system cache.


A smartphone that vibrates by itself can be a sign that malware is installed on it. You can get rid of them with an antivirus application.

Reset to factory settings

If all else fails, and the smartphone still vibrates for no reason, you should try resetting it to factory settings . This action will delete all information on the device, so important files and data must be transferred to the cloud or to external media.
