+ | == Buggy Application == |
If your touch screen only responds incorrectly or is unresponsive when using an application (or you aren't sure!) the first thing you should do is ***force*** ***restart your phone***. To restart your Galaxy S20: | |
If the screen is responsive in Safe Mode, it indicates that an app was the cause of the unresponsive screen. To fix this, delete the application(s) you were using when the touchscreen stopped responding, or those that were installed just before the problem started occurring. You can use a notification or a force restart to get your phone out of Safe Mode to check whether the problem persists. If it does, simply reboot your phone back to Safe Mode and continue deleting applications until the problem is resolved. If you aren't sure which app was causing the problem, then start deleting the most recently installed applications one by one. | |

+ | == Screen Protector Obstructing Digitizer == |
Screen protectors have been known to affect the sensitivity input of the Samsung Galaxy S20 touchscreen. The problem may present itself immediately after the protector is installed, or start acting up when the screen protector is damaged. If your phone is receiving no touch input at all, remove the screen protector to see if that solves the problem. | |
If replacing your screen protector, try looking for one that is designed specifically for the Galaxy S20, and ensure that user reviews don’t indicate that the screen obstructs touch sensitivity. | |

+ | == Dirty Screen == |
Dirt, dust, oil and water can all mess with your phone's touchscreen. Dirt and dust may reduce the conductivity of your fingers on the digitizer, while water and oils can cause the digitizer to register touch input where there is none. To remedy this issue, simply clean your phone's touchscreen: | |
# Wipe the screen clear of any remaining liquid with the dry part of the microfiber cloth. Leave any remaining moisture on the screen to air-dry. | |

+ | == System Freeze == |
Temporary files, an abundance of background processes, and system glitches can all cause your phone's screen to freeze, becoming unresponsive to further input. Most system halts will be remedied by restarting the phone, so if you haven't already, perform a ***force*** ***restart*** on your phone. To force restart your Galaxy S20: | |
# Press the ***Power/Bixby*** button to confirm the action to clear your phone data. | |

+ | == Broken Digitizer == |
The digitizer is a layer of sensitized glass integrated into the display of the phone that picks up the analog signals of a touch or swipe from your finger and converts it into a digital signal that your phone can comprehend. Because the digitizer is integrated into the OLED display on most phones (including the Galaxy S20 line), a broken digitizer likely means that you’ll have to replace the entire screen of your phone. | |
If the digitizer is damaged, you can replace it using one of our Galaxy S20 screen replacement guides: | |
