Your iPhone's touch screen isn't working due to software glitches, dirt, physical damage (like a cracked screen or bad connector), or issues with accessories like screen protectors/cases, often fixable with a quick force restart (Volume Up, Volume Down, then hold Side button until Apple logo appears) or by cleaning the screen and removing accessories, but if it persists, you might need professional repair.
Restart your iPhone or iPad. Make sure that your screen is clean and free of any debris or water. Disconnect any Lightning or USB-C accessories. If your screen works after removing an accessory, try using a different outlet, cable, or charger.
Your iPhone screen isn't working due to software glitches, physical damage, bad accessories, or environmental factors like extreme temperatures, but often a simple force restart (Volume Up > Volume Down > Hold Side Button) can fix it by reloading the software, while also cleaning the screen, removing cases/protectors, and disconnecting accessories can resolve interference issues before resorting to hardware service.
To turn a touchscreen back on, the method depends on the device, but for Windows, use Device Manager (search or Win+X) to find "HID-compliant touchscreen" under Human Interface Devices and Enable it; for Chromebooks, try Settings > Device > Touchpad or a shortcut like Search+X, or restart the device; for phones, a force restart (like volume buttons + power button sequence) often fixes temporary glitches.
Open Settings, then tap Display, and then tap the switch next to Touch sensitivity. The touchscreen may not work properly if you wear gloves, have dust on your finger, or touch the screen with fingernails or a ballpoint pen. It may also not work if a conductive object, such as a coin or key, is close to the screen.
If your phone's touch screen suddenly stops working, first clean the screen, remove the case/protector, then force restart (hold power + volume down for 10-15s) to fix software glitches; if it's still unresponsive, it's likely a hardware issue needing professional repair, potentially a broken screen or digitizer, or perhaps overheating.
Capacitive touchscreens typically last 5-10 years with proper care and maintenance. Industrial-grade displays may exceed 10 years in controlled environments, while consumer-grade screens generally provide 3-7 years of reliable operation depending on usage patterns and environmental conditions.

Here are the telltale symptoms of an iPhone's broken LCD:
If your phone's touchscreen is unresponsive and won't turn off, first try a forced restart by holding the power and volume down buttons simultaneously for 10-15 seconds. Check for screen damage or dirt obstructing touch sensitivity. If the problem persists, boot into safe mode to rule out app conflicts.
