Have you ever experienced something strange on your Samsung phone? On ajakteman.com , there's an interesting question from a Galaxy A35 user who suddenly noticed a black cursor appearing in the center of the screen while the phone was on and hadn't been touched for a few seconds. It's strange, especially since the cursor disappears when the screen is touched again, and even more confusing, it can't be captured in a screenshot .
Well, this isn't just a single device. Many Samsung users, especially those who recently updated to One UI 7.0 , are reporting similar issues. The question now is, what exactly is causing this mysterious cursor to appear , and how can you disable it ?
Let's discuss it in more depth.
Black Cursor Suddenly Appears on Samsung Screen
Common Symptoms Experienced by Users
Based on several user experiences that we have summarized, the symptoms are as follows:
- A black cursor shaped like a small dot or circle appears in the center of the screen.
- Appears when the screen is on and left idle for a few seconds.
- It disappears immediately when the screen is touched or tapped.
- Cannot be captured via screenshot, as if the system does not detect it as a UI display.
- It often occurs after connecting the phone to a Bluetooth device , such as a TWS, smartwatch, or speaker.
If you're experiencing the same issue, don't panic. It's not a virus or screen damage, but rather a system setting or incorrect device detection.
Main Cause: Incorrect Detection by the System of Bluetooth Devices
System Counts TWS or Bluetooth Speaker as Mouse
Samsung Galaxy (and Android in general) features a pointer accessory (like a mouse or stylus) that automatically activates when the system detects an external input device. In some cases, the system accidentally identifies a TWS or Bluetooth speaker as a pointer device , which is why a black cursor appears on the screen.
This Error Often Occurs After an Update
Some users reported this issue appearing after the One UI 7.0 update , which allegedly triggered a change in the way the system handles Bluetooth connections. As a result:
- Certain Bluetooth devices are recognized as pointer input (mouse).
- The system displays the default cursor for the pointer device.
- Since there is no real mouse, the cursor just stays still and disappears when the screen is actively touched.
How to Fix a Black Cursor on a Samsung Phone
1. Check Accessibility Settings
First steps you can try:
Clear input device preferences
- Go to Settings > Accessibility .
- Select Interaction and dexterity .
- Look for the Pointer/Mousetrack option (if present) and disable it .
2. Temporarily Disconnect Bluetooth Connection
If you suspect the cursor appears after connecting to a Bluetooth device, try this:
- Turn off Bluetooth and see if the cursor still appears.
- Restart your phone and reconnect only to devices that are absolutely necessary.
3. Remove Suspicious Bluetooth Devices
The method:
- Go to Settings > Connections > Bluetooth .
- Tap the gear icon next to the paired device.
- Select Delete/Forget .
- Restart HP.
4. Disable Pointer Input Manually (Developer Options)
If it still appears, enable Developer Options and turn off pointer input.
The steps:
- Go to Settings > About phone > Software information .
- Tap "Build number" 7 times until the notification "Developer mode has been enabled" appears.
- Go back to Settings , go to Developer Options .
- Find and disable "Show pointer location" or any feature related to pointer input.
Additional Factors That May Be Involved
It could be due to a third-party application.
Some third-party remote or TWS apps may display a cursor when they detect a device as an "input controller." For example:
- Remote control application
- Smart home application
- Emulator game
Try uninstalling these applications one by one to see the effect.
One UI System Bug
Since many people have complained about it since the update, it's likely a minor bug that will be fixed in the next One UI update . Make sure you check for system updates regularly:
- Settings > Software Update > Download and install .
So the conclusion…
The black cursor that appears in the center of the Samsung phone screen, especially after the One UI 7.0 update, isn't a screen malfunction or a virus, but rather a result of the system misdetecting a Bluetooth device. Typically, the system mistakenly considers a device like a TWS or smartwatch as a mouse, causing the cursor to automatically appear.
To overcome this, you can:
- Temporarily disconnect Bluetooth
- Disable pointer or external input settings in accessibility
- Use Developer Options to disable pointer-related features.
- Remove suspicious Bluetooth devices
If all the methods above do not solve the problem, please be patient until the next One UI update is released , because this is likely a minor bug in the latest version.
