The phone just does not turn on what to do. What to do if the phone does not turn on: main problems and solutions. Full battery discharge

When your phone does not turn on, there is no benefit from it, you understand. But why does he refuse to work? Let's try to consider the most common cases and solutions on how to be and what to do if the smartphone does not turn on.

The same situation can have very different roots. In some cases, you will get off with a few minutes spent, in others you cannot do without contacting specialists. But in any case, it is better to be prepared and know everything possible in advance.

Possible causes and solutions

Let's try to consider some cases. Sometimes the problem can be eliminated by simply looking at it more carefully. And if you still have to contact the workshop, you will know what to prepare for.

The battery is dead or defective

One of the first reasons why a smartphone does not turn on is battery drain. It doesn't take long for modern phones (especially powerful flagships) to use up a full charge; some of them, with active work, sit down in a matter of hours. And if you accidentally left a resource-intensive game or a flashlight utility on, then this is generally a nightmare! You may not expect the battery to run out so quickly.

First, try charging your phone. If it charges and turns on (not immediately, after a few minutes) - the problem is solved.

If not, but the battery in it is replaceable - do not be too lazy to go to the store and try the same with another battery. If the problem is solved in this way, then you will not have to go far for a replacement.

Worst of all, if the case is non-separable. Then you cannot avoid going to a service center or a workshop.

Charger

Frankly speaking, one of the simplest cases. If your mobile phone, having completely discharged, cannot turn on again - maybe it just does not charge?

Just test it with another charger. If charging starts, then, obviously, the matter is in the charger. You can also check the problem charger in parts - a separate adapter and a separate USB cable to replace the non-working component.

power button

The power button is perhaps the most commonly used on the phone. And for the same reason - the most vulnerable. It can be damaged if your "patient" falls successfully - on a button or a corresponding board, or simply from heavy use.

It's good if your phone has alternative ways unlocking (for example, tapping on the display or pressing the Home button), but, alas, they are not suitable for turning on a turned off device.

Check that with the button, it will turn out only in the conditions of a repair shop.

However, there are ways that can help you at home:

However, all these methods are just a straw for a drowning man. There is a high chance that none of them will help. Then your road is straight to the workshop.

Socket not working

This reason is rather anecdotal, but it also takes place. So, if your mobile gadget is dead and does not want to turn on even when plugged into an outlet, try connecting it to another outlet that is known to be working. Perhaps, in fact, you do not need to carry your mobile to the workshop, but call an electrician to your house.

Problems with the charging connector

In the era of Micro USB, of course, it is problematic to bring the connector to complete wear and tear. However, this happens, especially if you use cables from other manufacturers.

So, for example, manufacturers of advanced cases often complete their gadgets with a cable with an extended plug, which can be used to charge the device without removing the case. But attempts to fully insert such a plug directly into the connector can end in failure.

In this case, you need to try whether the gadget is charging from other chargers (and yes, from other outlets!) If so, then we can assume that you got off lightly. If not, then you will have to change the connector in the workshop. Fortunately, replacing the connector is not the most difficult technical task.

Software failure

On the forums of Android connoisseurs, terms like "brick" or "bootlap" are often found. They do not mean anything good: “brick” is an Android device that flatly refuses to boot after firmware, and “bootlap” is a constant cyclic reboot.

Why does this occur?

• the firmware process was interrupted. For example, by negligence, a child, a cat, or you yourself pulled the cable out of the socket. Or your electricity was cut off; that is why it is better to use laptops with a fully charged battery for flashing.
• you tried to install firmware from another model on your phone. Sometimes the same model is produced for different regions in different modifications, which also affects the software.
• you did not carefully follow the instructions that are necessarily attached to each software update.

What to do? Each model has its own recovery procedure. Since you undertook to flash Android yourself, it means that you have elementary ideas about the basics.

As a rule, to restore devices in the bootloop, you either need to clear all the data, or upload the correct firmware version to the memory card and install it through the Recovery menu. How to enter this menu depends on the specific model of your "patient".

"Bricks" are usually restored through a computer. For models based on different chipsets, there are separate recovery utilities. Unfortunately, this is too broad a topic to cover in one article.

Update error

Upgrading your OS is now easier than ever. In most cases, it comes "over the air": you do not need to download the firmware image to your computer and connect with a cord. The image is downloaded directly to the device memory and installed from it.

But sometimes there are process errors. For example, if there was not enough memory to unpack the archive. Or if the battery died right in the middle of installing an update.

As a rule, there are protective measures and recovery methods in the OTA update mechanism. But if they do not work, you will have to install the firmware in the old way, through a computer. How? - look for details specific to your model. Or again, contact the experts.

Mechanical problems

Modern smartphones are quite fragile technology. Even models with protection, which are pretty good at resisting scratches and abrasions, can be hit so that they suffer. What can we say about fragile budget cases and displays without protective glass!

Usually, if the device does not turn on due to a fall, the cause of the problem is visible to the naked eye. The display could have survived, but the lid could fly off, cracks and dents could remain on the case. This is enough to damage the electronics.

The following options are possible:

• communication between the batteries and the system board is broken. Then the smartphone turns off immediately;
• communication between the battery and the power controller is broken. In this case, the device will "die" after the battery is discharged and will not respond to an attempt to charge it;
• the battery is damaged. Various manifestations of the problem are possible;
• the system board is damaged. Perhaps the saddest of the situations. The problem can manifest itself immediately, and some time after the fall.

In any case, if your smartphone has started to junk even a little after a fall, bring it in for repair.

What to do if the smartphone fell into the water and does not turn on

It's hard to imagine your phone falling into water and getting wet without your knowledge. So, you managed to swim with him through the lake without noticing the swimming shorts in your pocket. Or dropped into a deep puddle, so deep that it took a while to find it. In general, the newly found device does not turn on, no matter what buttons you press.

Exist general instructions on dealing with "drowned":

Maybe this procedure will not save. But at least you will know the cause of the problem when you go to the repair shop. Tell it like it is.

There is no need to hope that the case will be regarded as a guarantee, to hide your awkwardness or be ashamed of the trouble that happened to you. This will not increase the cost of repairs, and specialists will be able to quickly find the affected components.

Of course, a faulty smartphone can be taken in for repair immediately, without trying to fix it yourself. But sometimes the cause of problems is ridiculously simple, and you just need to understand it in order to fix it.

Some other cases require some action on your part (especially software failures), but by delving into the problem, you can avoid spending money and wasting time. We hope this material has helped you in the fight against malfunctions.

Today we cannot imagine ourselves without means of communication, such as a mobile phone. Sometimes the phone fails for reasons unknown to us. To figure out why it refuses to work, we propose to consider the main reasons for the breakdown of the phone.

Visually examine the phone for mechanical damage. If there are none, the battery may be dead. You should charge your phone by leaving it plugged in for a day. If after this period the phone does not respond to commands, you should contact the specialists at the service center.

Mechanical damage

If damage is found on external parts (case, display, keyboard), they can be replaced, both independently and with the help of a specialist.

No network signal on phone

There may be several reasons for this:

1. This network is not supported by the operator. Replace the SIM card with an operator that supports the network in this locality.
2. Perhaps the antenna (radio path) is out of order. Only the service center will help you to cope with this problem.

Display blank

The main reason is moisture, which for one reason or another got into the phone. The problem is usually fixed by cleaning the phone.

The reason most often lies in the software failure. The second reason is if the phone has been dropped frequently. You will be helped only in the service center.

Fast battery drain

This usually indicates that you have a bad battery and should be replaced. Another problem may lie in the power amplifier if the phone is discharged when receiving a call or dialing (due to the fact that the phone was often dropped). We replace the battery, if it does not work, then we go to the service center for help.

The smartphone does not see the SIM card

Several reasons for this problem:

1. this SIM card has expired;
2. the SIM card ran out of money;
3. not supported by this operator;
4. pollution and oxidation on the SIM card;
5. case in the card reader

Just turn off the phone

Possible failure in the self-sustainment program. Bad connection of the battery with the contacts in the phone. The elements or the printed circuit board itself are out of order (in case of mechanical damage). Low air temperature can also be one of the reasons for turning off the phone.

In case of serious problems with the phone, we go to the service center for help!

Breakdowns and system errors of the Android OS do not happen all that often, but owners of modern tablets or smartphones need to know how to act in such cases. Our article will tell you why the phone does not boot beyond the android logo and how to fix this problem.

The problem occurs when the system is rebooted, especially when the phone turns off on its own after being hit or dropped. The device refuses to fully boot up, even with multiple on / off, only the Android splash screen or the zte logo appears on the screen.

Causes of problems with loading the device

Situations like this don't happen out of nowhere. The reasons can be classified as hardware and system, mainly we are talking about typical cases.

The main reasons for download failures are:

1. Mechanical damage. Falls of your gadget negatively affect the operation of the entire device as a whole. Usually, after an impact or other type of mechanical impact, the phone or tablet does not turn on completely, but problems can also manifest themselves as a failure to boot the device further.
2. Not enough memory. If there is not enough space on the internal or external media, it may take a long time to boot the system. Often in such cases, the tablet or smartphone does not turn on at all.
3. Wrong flashing. This is the most common reason for contacting a service center. When flashing the system on your own, or with the help of the same "specialists" from among your friends, the update process may fail and the phone (tablet) will refuse to boot at all. Such a problem can also arise when contacting an uncertified workshop, whose workers are not properly qualified to perform such manipulations.
4. Complete discharge of the battery. A fairly rare cause of problems with smartphone downloads, but it cannot be completely ruled out.
5. Damaged and stuck power button. Switching on in this case occurs in a cycle, not reaching full load. It is possible to diagnose such a problem only in a service center.
6. Memory card incompatibility. Rarely, but there are situations when it is a new flash drive that interferes with the normal operation of the device.

Possible troubleshooting steps can only be taken after the cause of the problem has been determined. It will be difficult to do it yourself, unless we are talking about mechanical damage to the phone. Otherwise, it is better to trust the professionals and contact a good service center according to the profile of your model.

What to do in this case

If you are faced with the problem described above that the Android smartphone does not load beyond the logo, you can try to fix the system failure yourself. If a smartphone or tablet “survived” a serious fall, overheated or came into contact with liquid, it is unlikely that it will be possible to restore functionality without professional help. If we are talking about a system error, you can act according to the above algorithms.

What actions help in such cases:

• The first thing to try is to reboot the device. In about half of the cases, this helps to turn on the gadget, after which you can diagnose the system, check the memory and the operation of applications.
• Charger connection. Also simple and effective method solving battery problems. If the screensaver on the phone has changed to a charge icon, you must wait until the process is completed and try to turn on the phone again.
• If the device malfunctions after flashing, a simple reboot of the system will be ineffective. To restore the device to working capacity, you will need to reset the settings to the factory settings. This may result in the loss of files stored on the internal storage.
• To delete all the changes made when flashing the device, you need to go to the Recovery Mode menu. Usually, to do this, you need to press the combination of volume and power keys on the switched off phone (combinations depend on the model of the device). If such manipulations do not affect the system, then the problem lies much deeper and it cannot be solved on its own.
• In the proposed menu, you can select one of the options for updating the system. The “Wipe data factory” section will help you reset the settings to the factory settings, so the data installed during flashing will be deleted. To activate this mode, you need to find and confirm the “Reset” item in the section. The device after this procedure will reboot and update.
• If the failure appeared for an unknown reason and this was not preceded by a fall or software changes, you can flash the device. It is not recommended to do this on your own, unless you know for sure the optimal algorithm and a program that is fully compatible with your gadget.
• If the system conflict is related to the installation of a new drive, it is recommended to remove the memory card and reboot the system. Typically, such troubles happen when the phone is incompatible with the drive model, or if specifications memory cards far exceed the optimal physical capacity for such a device.
• If the problem appeared after downloading applications or installing updates, the best option would be to remove new programs. To do this, just turn on the device in safe mode and manually remove the possible "culprits" of the problem.
• The most difficult solution to the problem requires replacing or repairing the board and chips. It is best to do this in a service center, but the cost of such repairs, along with spare parts, is often not much lower than buying a new device. That is why this option is not so popular, especially since repairs do not guarantee trouble-free operation of the smartphone in the future.

The proposed actions are rather a recommendation, because system failures in the operation of the device are not always permissible to fix on your own. The problem can affect the programs and settings of your gadget much deeper, and inept actions will lead to a complete failure.

Android tablet won't load past the logo

Tablet system errors are in many ways similar to phone-specific problems. The Android operating system implies the same algorithm of actions for devices with different characteristics. By the way, it is often this freedom for the user that leads to system errors. When downloading a large number of applications and games, as well as using unverified services, viruses can also be “introduced” along with the program, so the best prevention of such risks is to pre-install protective applications and regularly update and scan the system.

Phone won't load past splash screen

Is your phone freezing and refusing to turn on? In addition to the above problems, you can consider several more options for such failures. First of all - breakdown of internal elements. Modern devices contain a lot of "smart" electronics, which are more sensitive to careless treatment.

Problems may occur in the following cases:

1. The smartphone is often completely discharged, and charging is insufficient.
2. The phone often overheats.
3. System crashes occur after installing updates with insufficient battery power.
4. After a virus attack or opening of potentially dangerous files and programs.

If it is impossible to independently determine the cause, as well as a serious breakdown of the device, it is recommended to contact a good service center and diagnose the device.

If your Android does not load beyond the logo, you should definitely eliminate the main causes of such problems. Drops and bumps, inept flashing of the device, as well as turning off the phone when the charge is low - this is what most often becomes a negative factor affecting the incorrect operation of the device. Our article will tell you what can be done in such cases and when it is better not to aggravate the problem with independent actions.

Sometimes smartphones or Samsung tablets Galaxy even for no reason can stop turning on. Crash occurs operating system Android, but most often users have problems due to pre-installed root rights. Now you will learn how to revive the device, if it is, of course, not a hardware failure.

There are several ways and we will start with the most obvious and simple.

Method 1: Check your charger and cable

Perhaps your Samsung smartphone is dead and will not turn on. You connected the charger but nothing happens. First of all, try to take a charge from another gadget, and if the phone reacted to it and began to receive a charge, then the problem is in it. Next, you should change the USB cable to determine what exactly has stopped working. If, after replacing the wire, your charger began to charge the battery of your smartphone, then the reason is its malfunction.

On the advice of Samsung technical support, we suggest trying the following very effective way to restore your mobile phone:

1. Press and hold the "Volume Down" and "Power" buttons
2. Hold them for 7-12 seconds
3. If after that your device started working, then a very common failure occurred in its operation.

If the problem persists, then move on to the next solution.

Method 3: Clear the cache

We format the phone's memory section, which stores the entire cache.


Did the attempt fail? After the reboot, the device did not work properly? Let's move on to more complex methods.

Method 4: Reset to factory settings

All data will be lost, including unsynced contacts, messages, call list, application data and files that are in the phone's memory. The contents of the memory card will remain intact.

Method 5: Flashing with ODIN

If the device did not work after resetting the parameters, then you should try to reflash it. We are looking for firmware for your smartphone model, download the ODIN program from this link and install drivers for Windows, and then proceed to the instructions.

Method 6: Taking the Samsung Galaxy to a Service Center

If none of the above solutions to the problem suit you and the phone still does not turn on, then you need to take it to a Samsung service center. They will probably find out the reason for the loss of working capacity.

Results

Now you know what to do if the Samsung Galaxy smartphone does not turn on. We hope you do not have to use these tips, and your gadgets will work without failures and any problems.

Mobile phones are functional, productive means of communication that have partly replaced PCs and laptops. The modern smartphone is built using the latest developments, but is still vulnerable to failures and physical damage. In this regard, users often have the question of what to do if the phone does not turn on. This is because it is not difficult to disrupt the performance of devices. However, often the reasons that the phone does not turn on are simple, and you can eliminate them after reading our article, which describes the reasons why the smartphone has stopped turning on, and also suggests methods for solving them.

Dead battery

One of the reasons why the phone does not turn on is a dead battery. To start your smartphone, connect it to the charger and hold down the "Power" button. Please note that sometimes the battery runs out so badly that it will take 10-20 minutes for the device to start up again. If this happens, we recommend that you do not remove the gadget until it is charged up to 100%.

Faulty charger

If the power supply is faulty, then it must be replaced with a new one, exactly the same so that it is compatible with the phone and supports the necessary charging technologies.

Until you buy a charger, replenish the percentage of the device's battery using the Power Bank or connect the mobile to the computer via a USB cable in charging mode.

Battery failure

As a rule, the battery on a smartphone begins to degrade after a year. After one and a half or two, you will notice that the device is not enough for a day, but for half a day or a little more. If your device is more than 3 years old, and it suddenly turned off, and you cannot start it, check the battery, it is probably out of order.

If the gadget has a removable battery, get a new one and the problem will be solved. However, most modern phones come with a non-removable battery. Therefore, it is better to replace it in a service center.

Charging socket failure

The smartphone may not charge due to broken charging contacts. If you are tech savvy and you have a screwdriver with a voltage indicator, you can try to repair the contacts yourself with tweezers. In any other case, go to a repair center or return the gadget under warranty.

Overheating or hypothermia

All mobiles do not tolerate high and low temperatures. Hot weather leads to overheating of the battery, it discharges faster and more actively loses its maximum capacity (try to never allow the battery to heat up above 45 ° C). The cold also becomes a test for phones (the device often just turns off). At low temperatures, the charge melts before our eyes. This problem is especially true for Apple smartphones, which have a very small battery capacity (high-capacity phones are more frost-tolerant).

If, due to external factors, the gadget can overcool, overheat, and then turn off and refuse to start for some time, wait until its temperature is balanced, and then try to activate it. You may need to put it on charge.

Broken power button

One of the reasons why the device refuses to turn on is the wear of the power button. A problem with it can arise after the gadget falls on a hard surface or due to banal wear and tear. Between the power key and the contact with which it interacts, there is a silicone or rubber layer, damage to which will prevent the phone from starting when the Power button is pressed. Go to the repair, there the device will be quickly diagnosed, and the replacement of the part, if needed, will be cheap.

Memory card problems

The phone may not turn on due to a defective memory card. This happens if it has virus software that blocks the start of the Android system (you need to check for viruses). We wrote in detail about how to get rid of the virus in one of the previous articles. In this case, it would be optimal to pull out the USB flash drive and check it for viruses through a PC. If that doesn't work, then format it.

Buggy firmware update

If the Android phone does not turn on, then the problem may be in the operating system update that you recently installed. This happens especially often after flashing to a custom (unofficial) build. There are several options for how to fix the situation, but we will have to do this through stock or custom recovery.

Option number 1. Reset to factory settings

Option number 2. Flashing to a stable software version

You should simply install the previous version of the firmware on your mobile, which worked stably. Depending on the phone, the procedure may differ, however, if you have a custom recovery (from which you installed a non-working OS), then do the following.

1. Throw the firmware file (if necessary, then the package Google Apps, which is called GAPPS, which can be downloaded from https://opengapps.org/) to the root directory of the device.
2. Enter recovery.
3. Open "Wipe - Advanced Wipe".
4. Check the boxes next to Dalvik/ART Cache, System, Data, Cache.
5. Move the slider at the bottom, wait for the process to finish.
6. Return to the main screen, go to "Install", select the firmware file, start the installation by swiping the slider.
7. Once completed, click "Wipe Cache/Dalvik Cache".
8. Next, install GAPPS in the same way, and then select "Reboot System".

Software updates

Now programs on smartphones weigh quite a lot. They constantly download updates to the phone, with which the device sometimes fails, the memory is clogged, from which the mobile phone reboots. Just uninstall the apps you don't use and you can turn on your phone if it won't turn on.

Display problems

The device does not turn on also due to problems with the display. If the metamorphosis described below occurs with him, then this is a signal that he is “dying” or the train has departed.

1. On the screen, different bands appear and disappear for no reason.
2. The brightness is severely reduced or the screen flickers.
3. White or yellow spots appear on the matrix.

If you have the skills and special tools, then you can try to repair it yourself. However, it is better to consult a specialist.

The factors described above affect the operation of the phone. Therefore, to extend the life of the device you need:

• in case of breakdowns, immediately contact the master;
• do not drop your smartphone;
• prevent it from getting into the water;
• install updates and applications from trusted sources.
