Quickly push and un-hold the Volume Up button and then repeat the same for the Volume Down button. Now, hold down the Sleep/Wake button till you see the Apple logo. Let the iPhone restart and you can see that the frozen screen is unfrozen.
If the iPhone force restarts not working, this could be due to a software glitch on the iPhone. If there are any such issues with the software, Apple constantly monitors and rolls out updates to fix them, so you need to check for software updates.
Restart your phone
If your phone is frozen with the screen on, hold down the power button for about 30 seconds to restart.
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.
There are many situations that might cause your iPhone 11 frozen problem. Launch many programs on iPhone device at the same time will affect performance, resulting in your iPhone to freeze. Besides, a corrupted program which need to update to the latest version can become the culprit.
Clean the touch screen and screen protector. Sometimes, a touch screen will stop responding due to built-up dirt and grime or problems with the case or screen protector. Since this is pretty easy to either deal with or rule out, it's a good idea to thoroughly clean your device if a reboot doesn't do the trick.
On most phones, press your phone's power button for about 30 seconds, or until your phone restarts.
Press and hold either volume button and the side button until the power-off slider appears. Drag the slider, then wait 30 seconds for your device to turn off.
Most of the time, your iPhone 11 freezes because of a software problem. A hard reset will usually unfreeze it, but that doesn't actually fix the deeper software bug that's causing the issue. Even if a hard reset fixes the problem, make sure to check for an iOS update.
We're also hearing about Face ID problems, issues with first and third-party applications, RAM management problems, Exchange problems, iCloud issues, visual voicemail problems, Bluetooth issues, Wi-Fi issues, sound problems, and quite a few complaints about abnormal battery drain.
The Apple iPhone XR has been rebooted. If the problem persists, try using a so-called 'hard reset' to solve the problem. With a hard reset, the device is reset to the factory settings. Note: In contrast to a soft reset, with the hard reset all your personal data, files and apps on the device will be lost.
We'd expect an iPhone 11 to last about 2 to 3 years, so until about 2025. This is fairly standard for the lifespan of Apple phones.
