So, if you are a Samsung Galaxy A73 user and having similar issue, then continue reading for this post might help you.

1. First solution: Force Reboot your Galaxy A73.

   
   Before anything else, we recommend you to do a force reboot on your device. This will rule-out the possibility that a minor glitch in the system is causing the issue.
   
   Doing this will refresh the memory of the device and close all apps running in the background and reload its services.
   
   So, if this is just a minor firmware issue, then this method will surely fix it.
   
   1. So press and hold the Volume Down button and the Power key for 8 seconds. This will trigger your phone to shut down and power back up. 
   2. When the logo shows, release both keys and allow your phone to continue the boot process. 
   
   After the reboot use your phone and see if the issue is fixed. If not, proceed to the next step.

2. Second solution: Check for screen damage.

   
   Screen damage is one of the common hardware issues that smartphone users were complaining about. Any damage to the screen may cause several problems and errors, and one of them could be an unresponsive screen.
   
   Although it may seem minor, it may lead to serious problems and can affect the functionality of the device and will trigger several errors. So, if more errors occur the more glitchy the device is, and the system will become slower until the touchscreen may become slow and become unresponsive.
   
   If you accidentally dropped your phone on a hard surface, then we recommend you to visit the nearest Samsung store or service center in your area to figure out how serious the issue is and fix it by the tech.
   
   However, if your device doesn’t have any hardware issues but the problem persists, then proceed to the next method.

3. Third solution: Remove screen protector.

   
   Assuming that your phone doesn’t have any screen damage,  one of the possibilities to consider is due to a screen protector on your device.
   
   Sometimes, due to thick screen protectors the sensitivity of the screen may become lessen, so, try removing it and use a soft cloth to clean it and see if the sensitivity improves.
   
   However, if the screen of your Galaxy A73 is still unresponsive or slow after removing the screen protector, then move on to the next method.

4. Fourth solution: Wipe the cache partition.

   
   Another factor that could trigger performance issues on smartphone devices is due to corrupted files and data in the system. By wiping the cache partition of your phone will ensure that old files and data stored in the system will be deleted and replaced by newer ones.
   
   Don’t you worry, this method won’t delete your important files and data. This is how you wipe the cache partition of your phone:
   
   1: Turn off the device.
    2: Press and hold the Volume Up and Power keys.
    3: When the Galaxy A73 logo shows, release all three keys.
    4: Your Galaxy A73 will continue to boot up into Recovery Mode.
    5: Press the Volume down key several times to highlight wipe cache partition.
    6: Press Power key to select.
    7: Press the Volume down key to highlight yes, then press the Power key to select.
    8: Once the cache partition is cleared, tap the Power key to select the Reboot system now.
   
   When the reboot is finished, try to see if your Galaxy A73’s touch screen is now responsive as before. If still not, then move on to the next solution.

5. Fifth solution: Perform a factory reset.

   
   Since all methods above failed to resolve the issue the best thing that you can do is to perform a factory reset.
   
   Compared to other methods, doing a reset is more complicated because you have to create a backup with your important files and data because all will be deleted during the process.
   
   But the good thing is, if this is just a minor-firmware issue, then this method will surely fix it.
   
   When the device is ready, follow these steps to reset your phone:
   
    1: Pull up the App drawer and tap the Settings icon.
    2: Scroll down and tap General management.
    3: Tap Reset to view the options.
    4: Tap Factory data reset.
    5: Scroll down and tap Reset.
    6: Tap Delete all to proceed.
    7: Enter your password and tap OK to reset your phone.
   
   For any minor issues, a reset will always be enough to fix the problem. However, if this doesn’t fix the issue either, then you have to get your phone checked.
