There are several reasons why a phone screen may not be responsive. First, FPT Shop will list a few common factors when the touch screen is no longer sensitive, which you can refer to below.

Reasons why the phone screen cannot be swiped

The touch feature on your phone is no longer working, simply put, the phone screen cannot be swiped, and there are many factors affecting the screen, including agents from both hardware and software errors, some reasons are as follows:

Phone dropped and shattered: Unfortunately, the phone is dropped or shattered, the screen is strongly impacted, it may be scratched and affect the touch feature on the screen.

Water or other liquid damage: Inadvertently, the phone is soaked in water, leaked oil, soaked into the screen, sometimes other parts such as microphone, speaker, charging port are also damaged alongside.
Screen protector peeling off over time: After a period of time, the tempered glass turns yellow, making the screen unable to swipe.
Ghost touch phenomenon: Appears when the screen automatically responds and performs touch operations without receiving touch from the user.
Incorrect multitasking settings: Or also known as software conflict phenomenon, often occurs when the phone opens too many tabs or runs too many applications, sometimes frequently using split screen, causing the sensor to fail.

Temporary fixes for both Android and iOS

Remove tempered glass and screen protector

With the main function of protecting the screen from impact, scratches, tempered glass or screen protector is an essential accessory for smartphones nowadays.

However, applying the tempered glass with too much force or skewed installation may limit the touch feature; swiping or touching the screen is no longer as sensitive as before.

Therefore, it is necessary to be gentle and accurate when applying tempered glass to the phone.

Use voice or Face ID to fix screen issues

Use voice or face recognition features to temporarily replace touching the screen, if the phone screen cannot be swiped, you can use these assistive functions to control some operations such as turning on/off, restarting the phone, however, this is not a long-term solution.

Some apps that can be used in this case are Voice Access, Eva Facial Mouse or Bixby… to control the operation of the device.

Restart the device

One of the simple but sometimes effective ways to fix the issue of the phone screen not being swiped is to restart the device. In case your phone has a screen conflict, turning it off and on will help the touch feature work normally again.

Fixing screen issues on Android

Enable safe mode

Activate safe mode to protect your phone from harmful apps, prevent unnecessary conflicts.

When Android encounters a screen issue, FPT Shop suggests that you start safe mode, Safe Mode, to ensure the touch works normally.

To do this, you turn off the phone, then press and hold the power button and the volume down button until the phone restarts, the Safe Mode option will appear in the bottom left corner.

Adjust screen latency

Screen latency is the response time of the screen when receiving touch signals from users, divided into two types: display latency and response latency, measured in milliseconds (ms). A low screen latency indicates that the touch function is performing its best.

To check the screen latency, you can use the Touchscreen Repair app which provides features to adjust the touch to reduce latency and increase sensitivity through performing tests to check the device’s response speed.

Check screen status with 3rd-party apps

Display Tester is an Android app capable of testing screen performance, including screen latency, color, brightness, contrast, dead pixels on the screen… Moreover, if your smartphone supports multitouch (Multi-Touch Test), Display Tester allows you to test multi-finger recognition on the screen.
