Undoubtedly, when a phone or tablet’s touch screen is unresponsive, smartphone operations become frustrating and irritating. What comes to mind is “how to fix a phone touchscreen not working.” Knowing how to fix them reduces the cost of professional service and the stress of visiting a technician and gives a sense of achievement. By experience, we have synchronized common causes of unresponsive screens and better ways to fix them.
What are the Causes of Unresponsive Screen?
Specks of Dirt and Dust.
Usually, when the phone screen protector is dirty, wet, or hot, its ability to register touches reduces. Another thing that dirt causes is ghost touches. Cleaning your phone screen with a lint-free cloth helps remove acid and specks of dirt accumulation on your phone screen.
Hardware Damages.
What causes most of the unresponsive touch screens is physical or hardware damage. The primary factors are phones dropping off, falling on the ground, and into the water. The usual aftermath of these accidents is the malfunctioning of the phone digitizer and the disconnection of the phone screen from the phone motherboard.
The masterstroke that works here is visiting a professional screen repair center. That saves you time and the stress and frustration of a faulty screen.
Software Issues.
A better way to observe smartphones is a device that has both software and hardware components. Glitches, outdated system software, or new updates play pivotal roles here. Fixing software issues is working the path through which it came. Updating your phone system software and rebooting your device treats that better. Treating glitches, antivirus, and resetting your device to factory settings solves this better.
Another software issue is the application malfunctioning. When your touch screen is not responding, a recently installed or updated app may be responsible. When this occurs, removing the application makes you get rid of the issue.
Calibration Issues.
Not common is the calibration issue, but we cannot deny that it causes an unresponsive phone touchscreen. Though calibration oversees accurate touch input, switching it off can cause an unresponsive screen. Also, accidental misalignment and software issues can affect this. You can fix the calibration using the phone settings app or downloading calibration applications.
Fix Hardware-Caused Unresponsive Touch Screen
Remove the Screen Protector.
Screen protectors do not just protect the screen; they also affect the touch screen. If the touchscreen becomes unresponsive after applying the screen protector, remove it. After that, check if your touchscreen responds.
Test the touch screen.
Noticing a touchscreen that is not working is a thing. Knowing what caused it is another thing. If you see an unresponsive touchscreen, test the phone touchscreen. You can do this using diagnostic tools or third-party applications, allowing your phone to show touches. To run a diagnostic test on your device, try these shortcodes on your dial:
- *#7353# for Samsung device
- *#3424#*#* for HTC devices
- *#7378423#*#* for Sony devices
- *#0*# for Motorola devices
- Select TSP Dot Mode or TSP Grid Mode to test the screen.
You can allow your device to show touches or pointer locations by following these steps.
- Open your app drawer and tap settings.
- Scroll down and tap the “system” option.
- Tap the “developer options.”
- Scroll until you reach the “input” column and activate the “pointer tap and location”
With this testing, you will know the affected part on your phone screen.
Another way to test your Android device screen is to use external applications available on the Play Store.
Knock the Touch Screen gently for a while.
Unresponsive screens sometimes occur when the digitizer cable is unstable on the motherboard. You can make your phone work again by gently knocks/taps. Be easy on your phone while doing this.
Take the device to service centers for screen replacement
Notably, hardware screen malfunctioning is hardly repairable. Visiting repair service centers works better. You can locate your phone repair service centers or professional repair centers near you to get your touch screen working again.
Fix Software-caused unresponsive touchscreen.
Restart your Android phone or tablet.
While having an unresponsive screen, unlocking the device is impossible. Before taking any step further, restart your device. To do this, press the power button for at least 10 seconds.
Remove SD and SIM Cards
It may sound absurd, but SD and SIM cards can cause an unresponsive screen. To fix this, remove all external storage–SIM and SD Cards–and reboot your device to see if the screen is responsive.
Cross-check recently installed apps on safe mode.
Incompatible new or recently updated applications and malware can cause an unresponsive screen. If you notice an unresponsive touch screen, try using your phone safely. To on your device in safe mode:
- Restart your phone by pressing the power button.
- Press the power button till the phone manufacturer logo appears on the screen.
- As you lift your finger from the power button, long press the volume down button
- Wait till your phone shows the safe mode label.
If the unresponsive screen disappears in safe mode, one app is the cause.
Turn off the developer option.
While activating developer options gives you more than a better feel, it can also affect the touchscreen. If your touch screen is not working after trying the safe mode, developer options may be the cause. To stop developer options:
- Open your phone settings app
- Scroll downward and tap system options
- Tap developer options to see if the developer options are on
- Turn the device option off and restart your phone.
Reset the device to factory settings.
Resetting your Android phone to the factory settings is a giant strike that solves most software-caused issues. Removing all data and applications can fix all applications and glitches that cause problems. You can do this using the Find My Device app or website or by booting your phone in recovery mode.
To use Find My Device, follow these steps:
- Visit the Find My Device app or website on any device and log in to your Google account
- After login, look for the device you want to reset to factory settings, click Erase Device Option, and confirm your choice.
After this, your device will reset to the factory setting
To reset your phone in recovery mode:
- Long-press the power and volume down buttons simultaneously on your phone in recovery mode.
- Use the volume button to navigate the list and select the factory reset
- Confirm your choice with the power key.
