How to easily turn off your iPhone?

Dear friends, today we will learn how to turn off the iPhone if the sensor or the lock button does not work. Naturally, such cases often happen to users. It happens that the device simply freezes and does not respond to pressing on the display. Or after an unsuccessful fall, the button to turn off the device stopped responding. But we hasten to please you: in any case, you can turn off the power of the apple smartphone without any problems.

First, let’s refresh our memory a little and remember how to turn off the iPhone in the standard way:

Take the device in your hands and hold down the lock key for a few seconds.
Two switches will appear: at the top and bottom of the screen. One serves to turn off the power of the gadget, and the other to cancel the operation, respectively.
Move the button to the right position using the appropriate swipe on the top panel and wait until the device turns off completely. Done!

If the lock button does not work

What should those people who do not have a button do to do? In this case, the method described above is completely inappropriate: if you hold down an inactive key for a long time, nothing will happen. Then we do the following:

Go to the machine settings menu and click on the “Basic” tab.
Scroll down a bit and find the item called “Universal Access”. Click on it.
In the list that appears, we will need the AssistiveTouch setting, which is located in the physiology and motor skills block.
Toggle the slider to the active position, which is marked in green, to enable AssistiveTouch.

From now on, a new touch key will be available on your screen, when you press it, additional functions will open.
Go to the main menu using the Home button. Now click on the AssistiveTouch button and select “Apparatus”.
Next, in a new window, press and hold the “Screen Lock” button until the menu for shutdown appears (the second item of the previous block).
With the swipe you already know, you can turn off your iPhone without the lock button. Done!

But then an involuntary question arises: how to turn on such a device? The button doesn’t work, and Assistive Touch doesn’t work when it is off! In fact, the solution is very simple: connect your device either to a charger or to iTunes on your computer or laptop. In this case, the gadget will turn on normally.

If the touch screen does not work

After describing the method, we will tell you why. So, how to turn off your iPhone if the sensor is not working?

Take the device in your hands and simultaneously hold down the lock button and the “Home” key. Keep them pressed until the smartphone screen turns off. If you are using the seventh iPhone, then instead of the Home button, you will use the volume down key.

Hold down the lock button and the home key

The described method is a way to force reboot the apple device. It is used only in cases where other methods are powerless. Therefore, it is not recommended to use it frequently. If your screen is broken, take it urgently to a specialized service center, where you can have it replaced.

Another very simple and harmless way to turn off iPhone without a button is to simply wait. The question immediately arises in my head: what is the expectation? You just need to wait for your apple device to run out of charge and it turns off on its own. Then you don’t have to hard reset your smartphone, as described above.

Apple phones are one of the highest quality communication devices in terms of software and hardware optimization. But they are also prone to malfunctions and breakdowns. They also experience software glitches. The most unpleasant incident is often the inoperability of one or both buttons “Home” and “Power”.

Phones often stop working when they freeze. Buttons also fail. And turning the iPhone on or off becomes impossible. And then you have to figure out how to turn off the iPhone 5 (applicable to other iPhone models).

There are several popular ways to turn off iPhone 4 (applies to other iPhone models as well).

Why iPhoneX screen stops responding?

To force restart iPhone X, follow the steps below:

Press and release the volume up button.
Press and release the volume down button.
Hold the side button until you see the Apple logo on the screen, this will happen in about 10 seconds.
When the logo appears, release the side button and the device will boot as usual.

When the iPhone X turns on, the screen should work as expected. All touches should be instantly readable.

A forced reboot is not the most advanced solution, but it works and is very fast. Perhaps this is even the best way.

It is impossible to say for sure why this happens for no apparent reason. However, this is most likely a systemic issue.

Some time ago, Apple released iOS 11.1.2 update, in a postscript to which the following was said: “Fixed a bug due to which the screen of the iPhone X is temporarily unresponsive to touch at low temperatures.”.

Users also often write that the iPhone X screen freezes in the cold. In such cases, installing an iOS update can solve the problem.

Cold temperatures aren’t the only reason, however, and sometimes the iPhone X screen becomes unresponsive in warm rooms. There have been cases when this happened even on devices with iOS 11.2.6.

Most likely, this is another iOS system problem or a bug of some application. The device may stop working properly if the load is too high. That is why everything is working out after a forced reboot.

It’s also worth noting that the iPhone X is still a new model, so if the solutions above don’t help you fix the problem, you should contact Apple support. The problem with the screen occurred with both the iPhone 6s and the iPhone 7. Most often, the usual forced reboot, system update, or even restore helps.

Common causes of breakage

Most often, the iPhone screen does not respond to the touch of a finger after a fall, liquid penetration through cracks or due to other mechanical damage. The following defects are quite rare causes of problems:

touchscreen wear
high load of RAM (iPhone screen stopped responding, and buttons do not respond because the phone is frozen)
iPhone system malfunction (smartphone does not respond to button presses)
overheating of iPhones (in such cases, part of the screen does not respond to touch)

It is easy to determine the presence of problems in the operation of the sensor, the following failures are observed:

partly or completely unresponsive to iPhone touch
in certain parts of the display, the iPhone screen freezes when you touch your finger
the screen responds with a delay to touch
pages are flipped incorrectly
the sensor stopped responding to touches and spontaneously types text

To avoid problems with iPhone displays due to mechanical damage, the manufacturer recommends gluing glass or film to the surface of the screen.

Unstable operation or complete failure of the touch screen is often associated with the following reasons:

Mechanical impact (due to impact or falling of the phone).
Ingress of moisture into the case (moisture protection for Apple smartphones does not guarantee complete impermeability).
Overheating of the smartphone.
IOS software crash or freeze.
Poor quality protective glass or bumper.

Further in the menu when the dialog box appears. click “Update”. If the “update” fails, you can also try to restore the data from the backup.

So, in case of difficulties with buttons and a black, red or blue screen, the equipment needs to be charged, rebooted or updated.

But what if the iPhone’s problems are not related to the buttons, but to the sensor? There are hints here.

When the sensor on the iPhone is buggy, it’s even more “interesting” than the problems with the buttons.

Depending on the severity of the situation, the touchscreen can:

Do not respond to touch;
Hang on screen with finger.

And here again we need to figure out what became the primary source of the problem, since usually the iPhone sensor is infinitely resistant and very rarely breaks.

Software crashes. The reasons for their appearance can be excessive loading of the device’s RAM, as well as banal overheating. Such a breakdown is expressed through the freezing of the equipment. the incorrect behavior of the sensor and the lack of response to pressing buttons. Eliminated by forced reboot.
The display module is worn out. The iPhone sensor is an element of the display module, and in case of any breakdown of the sensor, protective glass or the display itself, you have to change the entire complex element. Repairs should only be carried out by professionals, since otherwise it is impossible to guarantee neither the quality nor the durability of the replaced part. The last problem is fixed only in the service, but as for the first block of software failures, then you can reanimate the iPhone yourself.

To combat freezing, the following methods are suitable:

Forced reboot;
Removing unlicensed software and cleaning the device memory from “garbage”;
Flashing iPhone.

For rebooting and flashing, you can use the same methods as for resuscitating the device in case of problems with the buttons. a combination of restart keys “from the manufacturer” and iTunes to restore a backup copy of data.

Any iPhone button or sensor malfunction should be resolved in two steps.

The first is an independent attempt, which in half the cases leads to success. If the experiment with restoring functionality is unsuccessful, there is no need to open the case and try to diagnose and repair the device.
A more correct way is to contact specialists who will accurately deal with the malfunction and eliminate it. Most often quickly and not very expensive.

How to turn off iPhone if sensor is not working

If your iPhone screen stops responding, you don’t always need to replace the display. In some cases, you can independently determine the cause of the problem and fix it. First, eliminate the possibility of damage to the case or screen surface.

If the internal components break, only a qualified technician can repair the iPhone.

If iPhone screen freezes, follow these steps:

use the power button to reboot the device (hold the button for a few seconds)
remove unlicensed software from iPhone
reflash the device

If, after performing such actions, the iPhone screen freezes, and there is no reaction to pressing the buttons, you must perform a complete restart of the device. To do this, you need to simultaneously hold the “Home” and “Power” buttons for 20 seconds. Then the smartphone will erase the RAM and restart the phone.

If after that part of the screen or the entire display still does not respond well to finger presses, the sensor needs to be replaced.

Potential consequences of rebooting without using a sensor

However, with frequent use, there is a possibility of losing information that is stored in the smartphone’s memory. Hard reboots can crash or completely damage the iPhone memory module. The number of hard reboots and module failure are not directly related, but the probability increases over time. Thus, do not neglect regular data backups to iCloud and try to use “Hard Reset” as little as possible.
