Fix: Galaxy S9 Touch Input is Blocked

Samsung’s Smartphones are very popular among the Android user community and Samsung manufactures about 46% of the total Android Smartphones being used by consumers. Samsung’s Flagship lineup of Smartphone is the Galaxy phones and they release one new Smartphone to the lineup every year. The Galaxy S9 is the 9th addition to the lineup and it comes with many enhanced features and improvements over its predecessor.

Touch Input Blocked Error message

However, quite recently a lot of reports have been coming in of a “Touch Input Blocked” error on the Smartphone and users are unable to use their phones while the error is on the screen and can’t perform any action until the message goes away.

What Causes the “Touch Input Blocked” Error on Galaxy S9?

After receiving numerous reports from users about the Touch Input error we decided to investigate the matter and put together a solution that solved the problem for most of our users. Also, we looked into the reason due to which the error is triggered and it is listed below.

  • Proximity Sensor: Most mobile phones use software to combat the pocket dials and accidental touches while the phone is not being used or is in your pocket. However, Samsung took another approach with the S9 that uses the proximity sensor that is on top of the phone by the camera sensor to identify if something is in front of the phone and if there is it does not register the touch. Therefore, if the phone was on standby and you unlocked it the phone might show the error if something is blocking the Proximity Sensor.
  • Hardware: On some devices, it was seen that a faint “Touch input Blocked” message could be seen at all the times and it wasn’t a screen burn issue either because the message could still be seen in screenshots.  Samsung acknowledged this issue and even did a press release upon the matter. Strangely, it was never fixed and replacements were provided for users whose issue could not be solved.

Now that you have a basic understanding of the nature of the issue we will move on towards the solution.

Disabling Accidental Touch Feature

Samsung Included a proximity sensor to reduce accidental touches from registering and although it was an innovative approach it also gave rise to the “Touch Input Blocked” issue. Therefore, in this step, we will be disabling the feature from the settings. For that:

  1. Drag down the notification panel and tap on the “Settings” icon.
  2. In the Settings, tap on the “Display” option.
    Clicking on the “Display” option in the settings
  3. Turn the “Block Accidental Touches” option off.
    Turning the “Block Accidental Touches” option off
  4. Check to see if the issue persists.
    Note: If you are observing the faint “Touch Input Blocked” message while using the mobile then contact the Samsung’s local authorized dealership and get a replacement for your device if it is still in warranty.
