If your android phone samsung, xiomi, lenovo, asus, zte, huavei, sony and so on freezes and has a non-removable battery, this is not a big problem.

Modern Android phones have hidden functionto manually restart the operating system.

It consists in holding the power button on the device not for five seconds, as usual, but for 20-30 seconds.

Such a prolonged action actually causes the phone to reboot. Of course, many owners mobile devices from non-removable battery if the phone is frozen, they feel completely helpless. This is why this guide was created.

There is absolutely no need for you to panic in this situation. Just keep holding the shutdown button for longer than the normal period of time

Sometimes it is necessary to simultaneously press and hold one more (volume down and power down) or even two buttons.

If nothing happened - there is absolutely no reaction, then you just have to wait until the battery is completely discharged.

Of course, I don’t want to wait, but it’s better than carrying it for repairs to be disassembled and rebooted. Let's dig a little deeper.

If your phone is frozen, there must be a reason. To prevent this from happening again, I recommend using free applicationwhich will check it and fix any errors. More about it and download

How I rebooted my frozen phone with a non-removable Samsung A3 battery

Although phones are improving all the time, sometimes progress can not play into our hands. This happened with devices with a non-removable battery.

Previously, in the event of a freeze, I quickly pulled out the battery, plugged it in again, turned it on and everything - the problem is solved.

Today, such reanimation on many android devices will not work, as, for example, on my samsung a3.

I was helped by the option of a combination of buttons "Power" + "Volume Down" for about ten seconds. The device has turned off and on.

Why android phone freezes and does not restart

If the phone is frozen and does not respond to any touch, then this is either a system glitch or a screen problem - in the touchscreen.

In practice, the phone freezes most often due to applications - they may not have enough RAM and some kind of error may occur.

If the battery is removable, then don't fuss, just pull it out for a minute - a 100% working way to get rid of freezes.

When the classic option does not work, the forced one remains: simultaneously pressing the "Off" and "Volume" buttons (what volume and even two at once depends on the device - xiomi, samsung, asus, sony, zte, lenovo, huavei)

What to do with an android phone to get rid of freezes

Sometimes it is possible to restart the phone, but the freeze keeps coming back. Then try

One of the main reasons for freezing is low performance (a weak device), so in such devices it is advisable not to apply effects, such as animated wallpapers - they heavily load memory and processor.

Also, do not overload even the memory card - this also contributes to freezing. Optimal balance when 10 percent of memory remains free.

NOTE: manufacturers of phones with an unearthly battery are well aware that the phone can freeze and not react to anything, therefore, they provide a way out of this situation - holding the shutdown button until the android OS reboots. You can also watch the video instruction. Good luck.

Every owner of a smartphone or tablet immediately after the purchase is very happy with the speed at which his device works. All operations are performed quickly, responses to touch are timely and without glitches with pictures. But over time, everything changes and performance deteriorates. Why does Android slow down?

Among the reasons that Android slows down or freezes, there are several main ones:

• inhibition of work can cause a large number of simultaneously running applications, albeit in the background;
• due to a recent update, a smartphone that did not slow down before may start doing this;
• any device can freeze even when free space begins to run out on it;
• a small amount of RAM can even cause the gadget to restart spontaneously;
• sometimes the phone may glitch due to problems with the touchscreen.

What to do if the phone starts to slow down for one of the listed reasons?

How to fix the problem

Cleaning applications

When the phone started to slow down a lot due to gluttonous applications and background processes, then to correct the situation you need:

• hold down the menu button, a list of recently launched applications will open, select "Delete all";
• in the Application Manager, view the list of running ones (opposite each one indicates the operating time and the amount of RAM it occupies) and forcibly stop every unnecessary one at the moment;
• in addition, you can remove live wallpapers and widgets, which also greatly affect the productivity of the device;
• applications that the owner of the gadget does not use, it is better to uninstall altogether in order to avoid running their processes in the background in advance.

Rollback update

Why does the device slow down after the update? The fact is that over time, any smartphone or tablet becomes obsolete, and each a new version Software or Android with its add-ons requires more and more powerful filling.

In this case, you will have to reflash your gadget with a return to the previous, workable version. This can be done in two ways:

1. Through Recovery. You must first download to your phone the version you want firmware and save on the memory card. Then enter Recovery (more often with a combination of the power buttons and the volume rocker down). Next, install the downloaded update and reboot the phone.
2. Through a computer. For this you need to download setup file from the manufacturer's official website and using the software supplied with the phone (usually on a disk), install it on the gadget connected to the PC.

After that, it is advisable to disable the function in the phone. automatic update system so that you do not have to repeat the procedure. It should also be remembered that after flashing all data from the phone may be lost, therefore it is better to make a backup first.

Freeing up internal memory and storage space

When the device runs out rAM, it tries to make up for it at the expense of internal memory... If its volume is too small, the phone may refuse to perform any actions. In this regard, you need to periodically perform the following actions:

• clear system and application cache;
• using special applications, clean the system itself (this will terminate background processes);
• sync media files on the cloud or with another drive and clean up from your device;
• do not forget to carry out the same actions with a flash drive, tk. a small amount of free memory on it also affects the performance of the device.

Sometimes, when the RAM runs out, it is enough to just restart the phone.

Screen Calibration

What to do if the sensor on the phone is buggy? In this case, you need to configure the problem display to correctly execute commands after swinging your fingers or stylus. This is also called screen calibration.
This need arises more often after mechanical damage or contact with water. And to be sure that the problematic sensor is on Android, you need:

• remove the film;
• try to enter any character on the keyboard.

If another number or letter pops up, the touchscreen will have to be calibrated. You can configure the sensor sensor using special programs (for example Touchscreen Repair), or manually. In the Play Store, you can find a large number of necessary applications, and free ones.
Self-calibration is carried out as follows:

• go to the "Display" tab in the phone settings;
• find the item with the title "calibration";
• put the phone on a flat surface and press calibrate (in some models the phone will offer a target, in the center of which you need to hit at least 3 times);
• reload the gadget and check the response again.

There is a function Assistive touch - therefore, restart the gadget with a disabled key " Power"Is simple enough. However, if the sensor is out of order, turning off the iPhone is more difficult: you will have to resort to Hard reset - an operation that could harm the device.

The need to turn off the iPhone without swiping across the screen, as a rule, arises when the device freezes during installation mobile application. The sensor also fails due to physical impact- for example, after a gadget falls to the ground. When the sensor freezes, most users immediately apply for warranty repair, not suspecting that they can do without the 45-day wait and fix the smartphone on their own.

The probability that after a reboot a frozen sensor will "resurrect" is 90%. But since the screen does not respond to touch, it will not work to turn off the smartphone in the usual way - you will have to make hard reboot... It is done like this:

Step 1... Press simultaneously two physical buttons - " Power"And" Home».

Step 2... Hold them until the Apple logo appears on the screen - about 10 seconds.

Then release the buttons.

Step 3... Wait 4-5 seconds and you will see the desktop of your mobile device.

On iPhone 7, you need to hold down the Volume Down key instead of the Home button.

How to turn off iPhone if sensor is not working?

If you just want to turn off the gadget, and not restart it, you should proceed a little differently:

Step 1... Clamp " Home» + « Power».

Step 2. Hold the buttons for 4-5 seconds - until the screen turns off - then release them. Don't wait for the "bitten apple" to appear!

After that, you can turn on the smartphone in the usual way - holding down the "Power" button for 2-3 seconds.

Not only the sensor problem is solved by a "hard reset". TO Hard reset they also resort if the iPhone has become poorly connected to the network or consumes too much energy.

Possible consequences of rebooting without using a sensor

If you apply Hard reset once or twice, negative consequences definitely won't... With a constant hard reset, there is a risk that the memory module will fail, as a result of which all data stored on the iPhone will be lost. There is a widespread opinion among users: each subsequent Hard reset increases the likelihood that memory "crumbles". However, this has not been confirmed by experts.

You should resort to a "hard reset" only as a last resort - when other ways to solve the problem have already been tried and have not brought any result.

Conclusion

"Hard reset" is the simplest and fastest measure aimed at returning the sensor to operability. But not the only one... If the user is afraid to produce Hard reset, he can refer to iTunes - the media combine will restore the device, and together with the restoration, the gadget will restart. There is an option for the most cautious users: wait for the smartphone to be discharged and turn itself off, and then "start" it in the usual way.
