Why are parts of my iPhone X screen not working?

I once had a similar problem, only to find it was due to electrostatic interference. Modern capacitive touchscreens, like the one on the iPhone X, can occasionally be disrupted by static electricity. Here’s what worked for me:

1. Restart your iPhone: Press and hold the Side button along with either Volume button until the sliders appear. Slide to power off, wait a few seconds, and then press and hold the Side button again to turn it back on.
2. Discharge static electricity: Touch a grounded metal object before using your phone, especially after walking on carpets.
3. Remove and reattach a case or covering: Sometimes, cases might also be carriers of static.

Electrostatic interference might appear sporadic, so it’s always good to observe whether this resolves the issue temporarily.

For me, the problem was related to background apps causing the phone to lag. I found that certain applications were consuming a lot of processing power, resulting in a slow or unresponsive touch screen. Here’s how I resolved it:

1. Double-click the Home button or swipe up from the bottom of the screen (for iPhone X) to open the app switcher.
2. Swipe up on each app to close them.
3. Check for any app that frequently crashes or behaves unusually.
   I also disabled Background App Refresh in Settings under General. This step significantly improved my phone’s responsiveness.

I encountered a comparable issue, which was due to moisture exposure. Sometimes, it doesn’t take full immersion for moisture to seep into the device’s internals. This can cause parts of the screen to become unresponsive. I took the following steps:

1. Powered off the phone immediately.
2. Placed the phone in a bag of uncooked rice or silica gel packets to absorb any moisture.
3. Left it there for 24-48 hours before attempting to turn it on again.

While this method isn’t foolproof, it resolved my issue. However, it’s not a guaranteed fix, and moisture can cause ongoing damage if not addressed by a professional.

You might be dealing with a hardware issue, specifically with the digitizer, which is part of the display assembly responsible for touch sensitivity. If certain parts of your iPhone X screen are not working, it could indicate that the digitizer is malfunctioning. It might have incurred damage even if the phone wasn’t physically abused. I suggest taking your iPhone to an Apple Store or an authorized service provider for a professional diagnosis. They can open your phone and check for loose connections or any issues within the hardware components.

In one instance, my friend’s iPhone X displayed similar behavior because of a faulty screen protector. Screen protectors can sometimes interfere with the touch sensitivity of the phone. If you are using a screen protector, try removing it and see if the problem persists. You might also want to clean your screen thoroughly with a microfiber cloth to remove any grime or residue that could be affecting the touch sensitivity.

I’ve experienced a similar issue, and it turned out to be a software glitch. Sometimes, an iOS update or a bug can make the touch screen less responsive in certain areas. In my case, restarting the phone helped temporarily, but the problem persisted until I performed a factory reset. Here’s what I did:

1. Backup your iPhone via iCloud or iTunes.
2. Go to Settings > General > Reset.
3. Choose Erase All Content and Settings.
4. Set up your iPhone as new, and then restore from your backup.

Even though this method worked for me, remember that you may lose data, so ensure your backup is current.

From my experience, the issue could also be related to a specific section of the phone’s logic board, particularly the connectors that link the screen to the motherboard. The iPhone X has intricate internals, and over time, connectors might loosen due to thermal expansion or minor drops. I tried:

1. Booking an appointment with an authorized technician.
2. Having them perform a thorough check of the connections.

Professional repair is often necessary since opening the iPhone X without the proper tools and knowledge can damage it further. This approach resolved my intermittent screen responsiveness issue conclusively.
