What to do if the phone does not turn on. After flashing the phone the phone does not turn on. Phone memory completely full

Discharged battery. For example, you forgot to charge the handset in the evening, and therefore the device in the morning. If your phone still doesn't work after you start charging, don't lose hope. Leave it to charge for 1 day. If the device still does not turn on after this, you need to look for the reason in something else.

The battery may have become unusable. To find out, open the back cover of the phone and carefully inspect the battery. The fact that it is faulty will be indicated by its swelling.

It is also possible that the charger was faulty. If possible, check its operation on another one. If it turns out that this device is working properly, then you should look for another reason.

If a memory card is inserted into the device, this may also be the reason why it does not turn on. Perhaps the card is blocking the startup process of the mobile phone. This happens especially often in cases where it is overflowing with information. In this case, remove the card from the slot and check if the phone turns on after that.

A strong mechanical impact on the device could have occurred, which caused a breakdown. It is difficult to determine this from the appearance of the phone case. However, the internal mechanisms of this device may have been damaged. In the event of such a breakdown, it is not recommended to open the device yourself; you should contact a specialist.

Mechanical damage most often results from:
- the device falls to the ground;
- damage by animals or small children;
- crushing in a bag or in the pockets of tight pants, etc.

Moisture can get into your phone, not necessarily because it has been exposed to water. It may be enough for the device to simply be in a damp room. In this case, you should also not take any action on your own; you should go to a specialist.

The reasons for moisture ingress may be the following:
- falling of the device into the toilet, bathtub with water, snow or pond;
- use in the rain;
- leaving a mobile phone outside during rainfall;
- fogging of the device, which is caused by its owner performing intense physical work.

If your smartphone does not turn on, it is possible that there is a software failure. You may, for example, need to update the firmware or roll it back. Another possible reason that the phone does not turn on is a broken power button. Determining this on your own is quite difficult. Such cases happen quite rarely, and they can happen due to the device falling from a great height.

What to do if the phone does not turn on?

First try to pinpoint the cause of the problem. If you managed to do this yourself, you need to think about what to do next.

So, if the problem was a faulty battery, it will need to be replaced. In the event of a breakdown inside the device, you will not be able to do without a service center. It is worth keeping in mind that repairing a phone is often more expensive than purchasing a new handset.

Sometimes smartphones fail; there can be many reasons, from an error in the phone’s firmware to a virus. You can use several methods to turn on the phone, but if none of them help, then it is best to take the phone to a service center.

If your Android phone won't turn on, you can try to turn it on.

Method No. 1. Reset factory settings on Android. Do not forget that this method will lead to the loss of all data that was saved on your smartphone. However, if the phone can be “revitalized”, then it will not be difficult to recover the data. To reset the factory settings, when the phone is turned off, you need to simultaneously press several buttons, the power button and the volume button. This will reset all settings so the phone turns on.

Method number 2. Reset factory settings. The first method of resetting factory settings is suitable for those whose Android phone does not respond at all to pressing any keys. The second method is for those devices that freeze at the loading stage. In this case, you can also reset the factory settings, to do this you need to dial code #3d5*361d4fb8#, this will result in the loss of all data, but the phone will turn on.

Method No. 3. Reflashing the device. If you do not know how to do this yourself, it is best to use the services of specialists from the service center. For those who can do the flashing themselves, you need to check whether the smartphone can switch to the “emergency mode” mode; to do this, you need to simultaneously press the “Return”, “Volume” and “Power” buttons. When carrying out this procedure, it is strictly forbidden to remove the battery from the device. If the smartphone enters the specified mode, it means that it is possible to flash it.

Virus. When using a device to access the Internet, there is a risk of receiving malware that not only deletes files on its own, but can also block the operation of the device. Therefore, if all of the above methods do not help you, it means that you have received a virus that has deleted all the files that are necessary for the operation of your Android smartphone. In this case, it is best to contact specialists.
When buying some smartphone models, you need to carefully monitor the updates that it offers, sometimes this is useful. There have been cases when an Android smartphone may stop working due to an unupdated firmware version; this is a warranty case, so you need to contact a service center. Now, you know almost all the reasons why an Android smartphone does not work.

What to do if your Android tablet does not turn on?

If your Android tablet does not turn on, there may be two reasons: either hardware, that is, problems with some spare part, or “software”, that is, an incorrectly installed operating system or installed incompetent programs.

Problems with the internal parts of the tablet may occur if you drop it or hit it. In this case, it will simply be impossible to repair it yourself. After all, the impact could damage the battery, some cable or board. In this case, it is best to take the faulty tablet to a service center. If you still decide to repair it yourself, then you can find diagrams of the boards and cable locations in order to check that they are connected correctly.

In the case of a software problem, it will be much easier to revive the tablet. To do this, you can resort to a hard reset. For all models, this procedure looks noticeably the same, but it is best to find instructions specifically for your tablet model. The standard hard reset procedure looks like this. First of all, you need to turn off the tablet if it freezes at the loading stage. To avoid data loss, it is better to first remove the memory card and SIM card. Then you should hold down the button to turn on the tablet and change the volume level. In some tablet models you need to hold down the volume up button, and in others you need to press down the volume button. (This is why it is better to find instructions for your specific tablet model). It takes about 10-15 seconds to press the buttons, this time also varies for different models. After this, the tablet should “respond” to you with vibration. In the menu that appears, select Settings, and then Format System. After this, the tablet must be rebooted.

Most often, this procedure does not help after the first time, so do not despair and repeat the procedure. If this method fails to restore the tablet’s functionality, then you can resort to flashing the firmware. It is best to entrust this to specialists who will not only repair the tablet, but also eliminate the cause of its breakdown.

Sometimes the reason the tablet freezes at the loading stage lies in a large number of downloaded applications, which are not always of good quality, so resetting the settings to factory settings helps 100 percent. In other cases, of course, it will be more difficult to repair it. In order not to risk permanently damaging the device, it is best to contact specialists, especially if the device is still under warranty; it is best not to take any action so as not to void the warranty.

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

Low battery

One of the reasons why the phone won't turn on is a low battery. To start your smartphone, connect it to the charger and hold down the “Power” button. Please note that sometimes the battery drains so much that it will take 10-20 minutes for the device to start again. If this happens, we recommend that you do not remove the gadget until it is charged to 100%.

Faulty charger

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

Until you buy a charger, replenish the device's battery using a Power Bank or connect your mobile to your 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 lasts not for a day, but for half a day or a little more. If your device is more than 3 years old and it suddenly turns off and you cannot start it, check the battery, it is probably faulty.

If your gadget has a removable battery, purchase a new one and the problem will be solved. However, most modern phones come with a non-removable battery. Therefore, it is better to carry out replacement at a service center.

Charging socket malfunction

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

Overheating or hypothermia

All mobile phones do not tolerate high and low temperatures well. Hot weather leads to overheating of the battery, it discharges faster and loses maximum capacity more actively (try to never allow the battery to heat above 45 o C). The cold also becomes a test for phones (the device often simply turns off). At low temperatures, the charge melts before our eyes. This problem is especially relevant for Apple smartphones, which have a very small battery capacity (phones with a large capacity can withstand frost better).

If, due to external factors, the gadget may 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 have to put it on charge.

Broken power button

One of the reasons why the device refuses to turn on is the power button is worn out. A problem with it can arise after the gadget falls on a hard surface or due to simple 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 you press the “Power” button. Go to a repair shop, they will quickly diagnose the device, and replacing the part, if needed, will be cheap.

Problems with the memory card

The phone may not turn on due to a faulty memory card. This happens if it has virus software that blocks the Android system from starting (you need to scan 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 remove the flash drive and check it for viruses via a PC. If this does not help, then format it.

Buggy firmware update

If your Android phone won't turn on, the problem may be with the operating system update you recently installed. This happens especially often after flashing firmware to a custom (unofficial) build. There are several options to fix the situation, but we will have to do it through stock or custom recovery.

Option #1. Factory reset

Option #2. Flashing to a stable software version

You should simply install the previous version of the firmware on your mobile phone, 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 operating system), then do the following.

Upload the firmware file (if necessary, the Google application package called GAPPS, which can be downloaded from https://opengapps.org/) into the root directory of the device.
Enter recovery.
Open "Wipe - Advanced Wipe".
Check the boxes next to Dalvik/ART Cache, System, Data, Cache.
Move the slider below and wait for the process to complete.
Return to the main screen, go to “Install”, select the firmware file, start the installation by swiping the slider.
Once completed, click on “Wipe Cache/Dalvik Cache”.
Next, install GAPPS in the same way, and then select “Reboot System”.

Software updates

Nowadays, programs on smartphones weigh quite a lot. They constantly download updates to the phone, which the device sometimes cannot cope with, the memory becomes clogged, causing the mobile phone to reboot. Just remove 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 due to problems with the display. If the metamorphoses described below occur to it, then this is a signal that it is “dying” or the train has left.

Various bars appear and disappear on the screen for no reason.
The brightness is greatly reduced or the screen flickers.
White or yellow spots “pop up” on the matrix.

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

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

in case of breakdowns, immediately contact a specialist;
do not drop your smartphone;
do not allow it to get into the water;
install updates and applications from trusted sources.

Modern smartphones are complex and quite delicate devices. One “fine” morning, you may find that the gadget that was put on charge refuses to work. Today we will figure out what to do if the phone does not turn on or boot, and also how you can fix this problem at home.

There are not many answers to the question of why the phone does not turn on, what could be the reason for its rapid discharge and what to do in such a situation. Let's look at the most common options and solutions.

Adapter faulty or missing contact

The most common reason why a phone won't boot or runs out of charge quickly is a faulty charger. To verify this, you need to connect the gadget to another power supply. If it starts charging, then you have found the reason and the problem was in the charger. You can do the opposite, connect a known good phone to a suspicious power supply. Thus, you are guaranteed to ensure that it is faulty.

If the smartphone does not charge from a working power supply, check the contact connector. It may become clogged with dust or pet hair. Carefully clean the connection socket on the phone with a wooden or plastic toothpick and try again.

If your phone has a removable battery, check the tightness of the contacts and their condition. There is a possibility that they were oxidized by moisture or bent when the battery was inserted after being dropped.

Another opportunity to “revive” the battery or make sure it is in good condition is to use a universal charger. In common parlance it is called a “frog” and is capable of charging any removable battery from a household electrical outlet.

SD card

One of the reasons why an Android phone does not turn on is the use of an SD card with a larger capacity than stated by the manufacturer. The desire to experiment is in the blood of users. If the specification says that you can only use 32 GB, you will definitely try 64. With a high degree of probability, the device will recognize the card. It will work normally until the recorded amount of information exceeds that declared for support.

If, after a software failure, the phone stops turning on or does not boot, just remove the problematic memory card from it. A forced reboot will return the smartphone to working condition.

System errors and failed updates

System errors, or a resource-intensive application that is not completely unloaded from RAM, can cause the battery to begin to drain rapidly, causing the phone to shut down and not start again. A malicious program can behave similarly. The virus, if its task is not extortion, works in the background. At the same time, he tries to use all available resources as quickly as possible. If your Android phone runs out of battery faster than usual while in standby mode, you should check it for infection and force a reboot. Further actions depend on the results of the anti-virus scan.

If the smartphone is clean and charged normally, there is no reason to worry. Otherwise, if the device does not start or the phone quickly runs out of power again, you will need a full reset and re-setup.

An unsuccessful software update can result in the phone not responding to user actions or simply turning off. Usually, this behavior is easily “cured” by rebooting.

If there is a failure when updating the firmware to a new OS version, the situation is a little more complicated. When the phone starts, but the boot does not go beyond the splash screen, the recovery mode can save the situation. It is best to find out what to do and how to enable Recovery Mode for a specific phone on the manufacturer’s website or in the documentation for the device. When this is not possible, try universal methods. The vast majority of Android smartphones support turning it on by holding down the power and volume keys. Whether it is an Up or Down button depends on the device manufacturer. You can try both options sequentially.

Hidden defects

Some users believe that physical damage occurs when the phone falls on a hard surface and shatters. Before that moment, he also fell twice, but only “slightly” scratched and crumpled. Meanwhile, we cannot rule out the appearance of hidden defects from impact on the gadget’s body. Damage to internal contacts will result in the Android phone not turning on or charging, or sometimes working and suddenly turning off. So if your phone falls, it is impossible to fix the motherboard malfunction on your own and you will have to contact specialists for a full diagnosis and possible replacement of components.

Finally

If the phone does not turn on even after you have gone through all the possible reasons, you should contact a service center. By not being too proactive in trying to revive him, you will save yourself time and nerves for specialists.

Among the frequent requests from service center technicians, there are problems when, for some unknown reason, the phone does not turn on and also does not charge. Of course, this causes a lot of problems, if only because the gadget turns out to be completely inoperable. Especially if important data is stored in memory without a backup copy.

Let's look at why this happens and how this situation can be corrected at home, without outside help.

The main sources may be:

System problems related to the Android OS itself. This can include viruses, crashes, and update errors.
Hardware components, that is, those related to the hardware and filling of the phone - breakdown of the display, battery, or any other mechanical damage. The latter arise due to falls, contact with water, oxidation and various deformations (torsion, compression, impacts).
External problems - most often due to a broken network adapter or power cord.

We will try to look in detail at each of the reasons why the phone stopped turning on and charging, and give practical guidance on how to behave in each case. However, if you are not sure that you can do everything correctly, contact the service center. Only a qualified technician can give an adequate assessment of the condition of the cell phone and advise the correct repair methods.

You may have to replace some parts, flash and install a working operating system, or buy a new charger.

Screen breakage

Often the root of problems with turning on is precisely the breakdown of the display. It is often misinterpreted and blamed on other problems. Multi-colored stripes may appear on the screen, it will stop responding to the owner’s taps or even show the picture.

It is in the latter case that many begin to believe that internal components have broken, the firmware has failed, or the battery has become unusable. But that's not true.

It’s worth noting right away that screen replacement is one of the most expensive repair procedures. Sometimes its price reaches half, or even ¾ of the cost of the device.

Therefore, if you have long been planning to change your old smart phone to a new model, a screen failure can serve as an excellent incentive.

The main causes of screen module failures:

Mechanical damage. To make the picture go dark and the touchscreen to stop responding to the owner’s fingers, it is enough to drop the cell phone from a short distance, sit on it, or press it with something. Smartphones do not tolerate bad treatment, so they need to be treated with care, not tested in extreme conditions, and immediately after purchase, protect them with a durable case or bumper on the back panel, and the screen with additional glass.
Water ingress is another conclusion that experts give after diagnosis. And we're not talking about spilled tea or falling into a full bathtub. Modern luxury gadgets are already protected from moisture, but cheaper and simpler models can break after exposure to rain, use with wet hands, or being in rooms where humidity exceeds 70%.
The last and not the most common reason is delamination of the resistive layer of the touchscreen. It happens rarely, but it has the right to happen. This happens after the smart device is exposed to direct sunlight for a long time, especially in hot weather. This is another proof that the gadget must be protected from overheating and hypothermia.

Whatever the problem, there is only one solution - a visit to the service center. You won’t be able to replace the screen at home, and a permanently broken gadget will cost much more than the services of a qualified technician.

Battery faults

Battery failure deservedly ranks first on the list of most popular requests. It is quite simple to understand that the problem is in the battery. If we are talking about battery wear, then this is a gradual process. First, the cell phone begins to charge slowly and discharge quickly, followed by spontaneous switching off and turning on, which ultimately leads to the “death” of the battery.

The reasons why the battery breaks may be as follows:

Wear and tear over time.
Physical influence.
Manufacturing defects.
Falls and blows.
Charging with Chinese adapters, or with mismatched current-voltage characteristics: too much voltage and current.
Oxidation of contacts.

Here, too, there is only one solution - replacing the battery yourself or having it serviced.

Faulty charger

If the phone is completely discharged and no longer charges, then the problem may well be a faulty charger. On modern models, the charging equipment consists of an adapter and a wire.

The breakdown can be in one or the other:

Due to power surges in the apartment, one of the components or both may burn out.
Factory defective equipment.
Incorrect operation, when the user bends the cord too much (the wires break and lose contact), storing components in places with high temperatures and where it can become dirty. If pieces of dust and debris get into the “teeth” of the wire, you can try to clean it with a regular needle. Fractures along the entire wire, if they are not critical, can be soldered at the nearest workshop (but then its service life will be significantly reduced).

Please note that you need to buy official certified chargers from the manufacturer. Low-quality Chinese counterfeits will not only quickly become unusable, but can also damage the smartphone itself.

Burnt out power controller

The power controller is a small chip located in front of the battery. In a number of cases described above, it can fail and burn out. To correct the situation, it is necessary to re-solder the part. It is highly not recommended to do this procedure yourself; serious aftereffects for the gadget are possible. The cost of repairs is not as high as it seems at first glance.

Update error

New firmware versions are regularly released for the Android OS, especially for the latest device models that can support such software. However, the system's automatic update process may experience problems. Each error affects the performance of the device, or can turn it into a “brick” that does not respond to user actions.

You can fix this problem by rolling back to factory settings, or as it is also called a “hard reset” or flashing it (this is best done at service points, because the gadget can “burn out” from home DIY).

Viruses

Android OS is susceptible to virus and hacker attacks. You can “catch” a virus while downloading programs, files or surfing the Internet.

It is better to prevent this difficulty than to solve it by downloading a good antivirus program (you can use a free one), for example, Dr.Web, Kaspersky, Avast.

Refrain from installing applications from unknown sources that require superuser rights, as well as Clean Master and the like. They have a negative impact on the operating system, other software, clog internal memory and wear out the battery by constantly running in the background.

Mechanical damage

Mechanical damage due to falls, impacts, water splashes and other physical interventions can also be sources of problems. Diagnostics and repairs will be carried out correctly only in certified service centers.

It is not recommended to replace parts or repair the phone yourself, especially if it is under warranty.

Conclusion

We looked at the main defects in devices and their components that lead to the phone refusing to turn on and charge. Some of them can be solved on your own, but with most it is better to contact a repair specialist. Refrain from doing it yourself if your phone is under warranty or you are not sure that you will do everything correctly. Sometimes it’s cheaper to take your phone to a service center right away than to fix collateral damage.
