Why is my iPhone glitching?

Your iPhone can glitch due to a cracked screen, the presence of liquid, apps running in the background and overheating the phone, and a weak battery that cannot provide sufficient power to the display. Some other reasons for your iPhone glitching issue are:

• Your iPhone is running an outdated iOS version.
• Your iPhone has a malfunctioning Ambient light sensor.

When this happens, your iPhone may exhibit unusual behavior in which the display abnormally turns on and off, becomes unresponsive, and even performs unintended touches, commonly known as “Ghost Touches.”

How to fix a glitched iPhone screen?

If your iPhone screen is glitching, below, we’ll mention the possible causes, why this happens, and how you can fix them yourself. 

I dropped my iPhone and the screen is glitching

Accidental drops or hits can crack your iPhone screen, causing it to start flickering, showing vertical lines, or even becoming unresponsive. 

Why is my iPhone screen glitching after falling?

Your iPhone screen may be glitching after falling due to physical damage, such as cracks in the display. The impact of the fall may also cause the connections between the screen and the motherboard to become loose or detached, leading to malfunctions.

How to fix a glitched iPhone screen after dropping?

One option to fix a glitched iPhone screen after falling is to attempt a force restart. To do this on iPhone 6 series, press and hold the Home and Wake/Sleep buttons concurrently until the Apple logo appears.

For iPhone 7 series, simultaneously press and hold the volume-  and Power buttons until you see the Apple logo. 

If you have an iPhone 8 series or later, press the Volume+ button and quickly release it; repeat the same approach with the Volume- button. Next, press and hold the Power button until the black screen with the Apple logo appears.

In case the screen is still glitching after force restarting, factory reset your iPhone. For this, go to “Settings” > “Transfer or Reset iPhone” > “Erase All Content and Settings,” and type in your passcode to confirm this action.

If the above solutions fail to work, the impact likely caused damage to the screen or display connectors. So it is best to ask a professional in your area to replace the cracked iPhone screen. 

iPhone glitching and pressing random things

iPhone glitching and performing actions by itself is the most common issue you may face, leaving you clueless about what causes it.  

Why is my iPhone glitching and pressing random things?

The most probable reason for your iPhone glitching, doing ghost touches, or typing itself is the presence of moisture on top of the screen or inside the phone, causing short circuits. Some other reasons for this issue can be:

• Using a faulty adaptor or lightning cable.
• Outdated iOS.
• Degrading battery.

How do I fix the ghost glitch on my iPhone?

To fix the ghost touches on your iPhone in case of exposure to water, turn it off and unplug any cables immediately. Remove the glass protector and rear protective casing, and thoroughly clean the phone with a microfiber cloth.

Now remove the SIM tray and gently tap your phone against your hand to get rid of the excessive water. Next, jerk the SIM tray opening facing down to remove the remaining liquid. Finally, place the phone in a warm environment for at least five hours to let it dry entirely before turning it on again.

iPhone screens flashing, showing odd colors, and suddenly dimming while editing videos, streaming movies, or capturing pictures can disrupt your experience.    

Why is my iPhone screen green and glitching?

Your iPhone screen may show green or other odd colors and start glitching due to a malfunctioning ambient light sensor, incorrect display settings, overheating, or bugs in a third-party app. 

What to do if my iPhone screen is flickering and dimming?

If your iPhone screen is flashing, dimming, and turning green, close all the background applications. For this, swipe up from the bottom of the screen, pause in the middle, and swipe up every app’s preview cards individually to find one with bugs causing glitches.

Once you find the culprit app, tap and hold its icon until it starts to jiggle. Next, tap the “Remove” icon in the app's upper-left corner, click Delete App, then tap Delete to confirm. You can reinstall that again with a bug-free version from the App Store.

If this does not resolve the issue, force restarts your iPhone by the methods discussed earlier. Otherwise, open “Settings” >  “Accessibility” > “Display & Text Size, ” and toggle on/off the Auto-Brightness option to verify the Ambient sensor isn't malfunctioning.
