1 Restart Your Phone:
Restarting your device is the first step to perform when your phone touch screen is not working for non-physical
damage. Sometimes, a simple restart can solve many issues. Since the touch screen is not responding, you
cannot turn your device off from the option on the screen. Here are the steps to follow to restart an Android phone.
Step 1: Press and hold the “Power” button until the device turns off. If you wait for a few seconds only, you will
see “Power Off” and “Restart” options on the screen.
Since the entire screen is not responding, it is of no use to you. Hence, you should press and hold the “Power”
button as long as required.

Step 2: Wait a few seconds when the device turns off.
Step 3: Press and hold the Power button for the device to get restarted.
2 Remove the Screen Protector or Case:
If you are using a screen protector or a case, it may interfere with touch sensitivity. Try removing them to see if
the touch screen works without them. Make sure the screen is clean from dust, dirt, or any other debris, Use a
soft, lint-free cloth to gently wipe the screen. It’s a easy way to clean your device if a reboot doesn’t do the trick.

3 Dry out Your Cell Phone:
If your phone gets wet or accidentally drops into water, your phone screen will become unresponsive. You can try
drying the phone in this case, which sometimes solves the problem.

If your phone drops into water, take it out immediately. You will need to remove all the removable parts of the
device. Use alcohol to wash your device to remove dirt and minerals. Keep your device parts in a sealed packet
of rice. The process dries off the device parts. Afterwards, place them outside to dry off to the extreme and see if
the problem is solved later.
4 Upgrade Your Operating System:

If there is a new operating system, updating it may solve the issue of ‘touch screen of phone not working.’ Please
make sure that your phone is connected to a stable Wi-Fi network before updating your phone. Then go to your
phone’s settings menu and look for “Software Update” or a similar option. Tap it to check for available updates.
If an update is available, your phone will prompt you to download it. Ensure your phone has enough battery, or
connect it to a charger. Follow the on-screen instructions to complete the update.
After installing the update, it may require a restart to finalize the process. Restarting your phone is recommended
to ensure all changes take effect.
5 Remove the SIM Card:
In some cases, hardware failure may cause the touch screen to stop responding, such as SIM cards and memory
cards, please try removing them and inserting them later. Be sure to turn off the power completely and unplug the
device first.
6 Optimize Device Performance:

Improving your phone’s performance with the Device Care feature may solve the issue. But, the feature is only
available on Samsung Galaxy devices. It scans for wasted storage space and identifies potential issues. To
optimize your device, go to Settings > Battery and device care > Optimize now.
7 Adjust Touch Sensitivity:
The exact steps may vary slightly depending on the device model and version of the operating system. Let’s take
the steps of Samsung and iPhone as examples.

For Samsung Galaxy device, please go to Settings > Display or Display & Brightness > Touch Sensitivity or Touch
Calibration, then follow the on-screen instructions to calibrate or adjust the touch sensitivity as desired.
If you are facing issues with an unresponsive or inaccurate touch screen on your iPhone (6S to XS), it could be
related to the sensitivity of the 3D Touch feature. To resolve this problem, you will need to make some adjustments.
Please head to Go to Settings > Accessibility > Touch > 3D & Haptic Touch, then follow the on-screen instructions
to adjust the touch sensitivity as desired. If the screen continues to be inaccurate or unresponsive, you can try
turning off the 3D Touch feature.
