Smartphones based on modern mobile operating systems - Android, iOS and Windows Mobile sometimes do not turn on or do it every other time. Problems can lie in both hardware and software.
The reasons why an Android smartphone does not turn on, as well as a device on a different OS, are often different. For example, it may not work when the battery has expired. Usually this problem occurs only on older devices. As a rule, it is preceded by a rapid drop in the charge in the battery for a long time, a long charge.
The phone battery may begin to oxidize (also usually true for older devices). If this starts to happen, then it is better to get rid of the phone as soon as possible, as there is a risk that the battery will ignite. A swollen battery is sometimes visible even from under the case.
In most cases, the smartphone does not turn on precisely because of hardware problems, so it will be very difficult to fix them at home. In the case of the problems described above, the battery will have to be disposed of, since it is unlikely that it will ever work normally, and replaced with a new one. Other problems can still be dealt with.
Issue 1: Battery not inserted correctly
Perhaps this problem is one of the most harmless, as it can be fixed at home in a few movements.
If your device has a removable battery, then you may have taken it out earlier to, for example, access the SIM card. Take a close look at how to insert the battery correctly. Usually the instruction is located somewhere on the battery case in the form of a schematic drawing or in the instructions for the smartphone. If it is not there, then you can try to find it on the network, as some phone models have their own characteristics.
However, there are cases when, due to an incorrectly inserted battery, the performance of the entire device can be seriously impaired and you will have to contact the service.
Before inserting the battery, it is recommended to pay attention to the socket where it will be inserted. If its plugs are somehow deformed or some of them are completely absent, then it is better not to insert the battery, but to contact a service center, as you risk disrupting the smartphone's performance. In rare exceptions, if the deformations are small, you can try to fix them yourself, but then you act at your own peril and risk.
Problem 2: Power button damage
This problem is also very common. Usually it affects devices that are used for a long time and actively, but there are exceptions, for example, defective goods. In this case, two options can be distinguished:
- Try to turn on. Most often, on the second or third attempt, the smartphone turns on, but if you have encountered such a problem before, then the number of necessary attempts can greatly increase;
- Send for repair. A broken power button on a phone is not such a serious problem and is usually fixed in a short period of time, and the fix is inexpensive, especially if the device is still under warranty.
If you find such a problem, it is better not to hesitate to contact the service center. The fact that the smartphone does not enter sleep mode immediately, but only after a few clicks on it, can also indicate problems with the power button. If the power button sinks or there are serious visible defects on it, then it is better to immediately contact the service center, without waiting for the first problems with turning the device on / off.
Problem 3: Software failure
Fortunately, in this case there is a great chance to fix everything on your own, without visiting a service center. To do this, you only need to do an emergency reboot of the smartphone, the process depends on the model and its characteristics, but it can be divided into two categories:
- Removing the battery. This is the easiest option, since you only need to remove the back cover of the device and pull out the battery, and then reinsert it. For most models that have a removable battery, the removal process looks almost the same, although there are small exceptions. Any user can handle this;
- The situation is more complicated with those models that have a non-removable battery. In this case, it is strongly not recommended to try to disassemble the monolithic case and remove the battery on your own, as you risk disrupting the smartphone's performance. Especially for such situations, the manufacturer has provided a special hole in the case where you need to stick the needle or knitting needle that comes with the device.
If you have the second case, then before trying to do something, study the instructions that come with the smartphone, everything should be detailed there. You should not try to poke a needle into the first hole in the case that comes across, as there is a big risk of confusing the desired connector with a microphone.
Usually, the emergency reset hole can be located on the top or bottom, but most often it is covered with a special plate, which is also removed to install a new SIM card.
It is not recommended to push various needles and other objects into this hole, as there is a risk of damage to something from the "insides" of the phone. Usually, the manufacturer puts a special clip with the smartphone, which can be used to remove the platinum to install SIM-cards and / or make an emergency reboot of the device.
Issue 4: Charging socket failure
This is also a common problem, most often found in devices that have been used for a long time. Usually, the problem can be easily detected in advance, for example, if you put the phone on charge, but it does not charge, charges very slowly or jerks.
If such a problem occurs, then initially check the integrity of the connector for connecting the charger and the charger itself. If defects were found somewhere, for example, broken contacts, damaged wire, then it is advisable to contact the service or buy a new charger (depending on what is the source of the problem).
If some debris has simply accumulated in the charging port of the smartphone, then carefully clean it out of there. You can use cotton swabs or discs in your work, but in no case should they be moistened with water or any other liquids, otherwise there may be a short circuit and the phone will stop working altogether.
No need to try to fix the detected defect in the charging port yourself, even if it seems insignificant.
Issue 5: Virus entry
It is very rare for a virus to completely disable your Android phone, however, some samples can prevent it from loading. They are rare, but if you become their “happy” owner, then in 90% of cases you can say goodbye to all personal data on the phone, since you have to reset the settings through the BIOS analogue for smartphones. If you do not reset the settings to the factory settings, then you will not be able to turn on the phone normally.
For most modern smartphones running the Android operating system, the following instructions will be relevant:
To understand if your device has been infected by a virus, remember some details of its operation shortly before you could not turn it on. Pay attention to the following:
- When connected to the Internet, the smartphone constantly starts downloading something. And these are not official updates from the Play Market, but some obscure files from third-party sources;
- While working with the phone, ads constantly appear (even on the desktop and in standard applications). Sometimes it may promote dubious services and / or refer to the so-called shock content;
- Some applications were installed on your smartphone without your consent (at the same time, you didn’t even receive any notifications about their installation);
- When you tried to turn on the smartphone, it initially showed signs of life (the logo of the manufacturer and / or Android appeared), but then turned off. A second attempt to turn it on led to the same result.
If you would like to save the information on the device, you can try contacting the service center. In this case, the chance that the smartphone will be able to turn on and get rid of the virus without going to the factory settings is significantly increased. However, 90% of this type of viruses can be dealt with only by a complete reset of all parameters.
Problem 6: Broken screen
In this case, everything is in order with the smartphone, that is, it turns on, but due to the fact that the screen suddenly failed, it is problematic to determine whether the phone turned on. This happens quite rarely and is usually preceded by the following problems:
- The screen on the phone could suddenly go “stripes” or start flickering during operation;
- During operation, the brightness could suddenly drop sharply for a while, and then rise again to an acceptable level (relevant only if the "Auto brightness adjustment" function is disabled in the settings);
- During operation, the colors on the screen suddenly began to either fade, or vice versa, became overly pronounced;
- Shortly before the problem, the screen could itself start to go out.
If you really have a problem with the screen, then there can only be two main reasons:
- The display itself is defective. In this case, it will have to be completely changed, the cost of such work in the service is quite high (although it depends more on the model);
- Loop fault. Sometimes it happens that the plume just starts to move away. In this case, it must be reconnected and fixed more tightly. The cost of such work is low. If the cable itself is faulty, then it will have to be changed.
When your phone suddenly stops turning on, it is best not to hesitate and contact a service center, as specialists will help you there. You can try to contact the manufacturer of the device through the official website or phone number, but he will most likely direct you to the service.
The Lenovo A319 phone is one of the best options for lovers of budget gadgets. The manufacturer has a good reputation, and the smartphone itself is quite inexpensive. Nevertheless, no matter how reliable the device is, one day you may encounter technical problems.
Many are worried about the question: what to do if the A319 does not turn on? And what if Lenovo a319 does not turn on and hangs on the splash screen? Many users of this gadget faced this problem. Since it is very common, we suggest that you familiarize yourself with the main options for solving it.
Option number 1. Reboot
We are all used to the fact that if some technique does not work, then it needs to be rebooted. And it is not at all necessary to find out why exactly it does not start or starts to turn on, but does not load to the end. There are a huge number of reasons for failures, and even experts cannot always name the problem that you encountered in a particular case.
So if the Lenovo A319 won't boot up or freezes when turned on, the best and easiest way to resolve the issue is to reboot your phone.
Have you tried restarting your device but that didn't help? Then repeat five more times. Getting the system to boot normally is not so easy, but multiple reboots in the vast majority of cases become successful.
You can also try holding down the home button and the power and volume keys at the same time. Some Lenovo models, including A 319, respond to such an impact and stop hanging.
The main advantage of these methods of solving the problem is the absence of any risk to the phone and the data stored on it. This is their main difference from the methods of returning the phone to life, which we will consider next.
Option number 2. hard reset
If an elementary reboot did not help, and still Lenovo a319 does not turn on or does not boot beyond the splash screen, you need to resort to more drastic measures. The best option is to reset all settings, or, in other words, Hard Reset the phone. To do this is quite simple - you just need to go into Recovery mode.
To make it easier for you to perform this procedure, we offer a simple algorithm:
- Turn off the phone by pressing the power key for 10-15 seconds.
- Simultaneously hold down the power and volume down keys. You can do this with one hand, but we recommend using both. There were cases when, through negligence, people dropped the device, trying to press both buttons with the fingers of one hand.
- We are waiting for the manufacturer's logo to appear, and after a few seconds we get into Recovery mode.
- Using the volume up and down buttons, select the "Wipe Data" item. It involves deleting all data and settings from the phone. Thus, whatever the software problem, most likely you will fix it.
- The system will ask you if you really agree to the deletion of all data. Confirm the action and wait about a minute. Then you agree to reboot the device and wait for the updated software to be downloaded.
If all systems start normally, and the phone functions as it did before the problems occurred, then congratulations - you have found a relatively simple and painless way to solve the issue. If the phone still does not turn on, or the download does not go beyond the splash screen, it remains to resort to the third method.
Option number 3. Flashing
The third method is the most radical, but you should definitely use it if the phone suddenly turns off, does not turn on or freezes. We act according to simple logic - if the system cannot be restored, then it should be replaced. In the case of computers and laptops, we usually reinstall the operating system, and for phones, firmware changes work.
First, download the firmware to your computer, and then transfer it to the memory card installed in the phone. The firmware is downloaded as an archive, and you do not need to extract files from it. We throw it on the card in this form.
Now we go to Recovery in exactly the same way as in the previous case, that is, by holding down the power and volume buttons. If there are installation files on the memory card, the system will recognize them by offering you the following item: install zip from sdcard. Just it is needed if the phone turns off and we need to change the firmware. Confirm the action by starting the file upload.
The flashing usually takes a few minutes. Do not be alarmed if the phone turns off during it - this is quite normal. It can reboot, and repeatedly. And this is not a cause for concern.
After several reboots, the system will turn on, and, most likely, you will no longer see freezes and brakes. This means that the problem is in the past, and now you know how to turn on the phone, which started to slow down or does not turn on.
Modern electronics needs both hardware power and appropriate programs. If the most powerful Android tablet cannot be launched, there is no point in it. However, in most cases, a device that has fallen into such a binder can be saved.
The nature of the problem
Why do troubles arise when the tablet turns on, but does not load beyond the logo (as, indeed, smartphones), or does not turn on at all?
- Flashing error. Similar incidents happen if you (or the unfortunate master from the service center) try to install firmware intended for another device on the tablet. Perhaps during the installation process, a power failure suddenly occurred, and the computer from which you installed the firmware turned off.
- Complete discharge of the battery. A fairly rare cause, but it does occur (particularly with Lenovo tablets).
- Clogged memory. When loading, any modern device needs free memory (). If there are problems with it, the tablet may take an unbearably long time to load and never fully boot.
- Mechanical damage. As a rule, they manifest themselves in the complete failure of the device to turn on, but there are exceptions.
With the tablet turned off, we are unlikely to be able to make an accurate diagnosis (except for cases of mechanical damage, traces of which remained on the body). But recovery methods are in any case common.
How to solve the problem?
recovery mode
Modern Android devices are equipped with special recovery tools. Recovery Mode is designed to work with the system "at a low level". Through this mode, you can install a new firmware or a program deeply embedded in the system (for example, Google Apps). But the easiest way is to enter Recovery Mode and reset the system.
For different models, the entrance to the recovery is done in different ways. As a rule, to do this, you need to turn off the device, and turn it on again, hold down the power button along with the already pressed volume up (or down) key. However, some manufacturers are getting creative and applying their own solution (for example, with the Home button - like Apple). Therefore, before the procedure, search the Internet for how to enter recovery mode specifically on your model.
In the menu that appears, the touch display will not work. Move up and down through its items with the volume buttons, and confirm with the power button. Select Wipe Data Factory (factory reset), apply it. After that, select Reset (reboot) and reboot the tablet in normal mode.
Of course, if you haven't made any backups, then your apps and personal data will be reset. But it's not hard to restore them, especially if you've enabled the persistent .
Flashing via computer
If you can’t enter Recovery mode, then try restoring the tablet through a computer. There are many utilities for this purpose, however, for each specific model (or chipset) it is necessary to choose the right application.
So, for tablets on NVidia processors, the developer released a special application called NVFlash. To flash models on RockChip, there is an application RockChip RK Batch Tool. Other manufacturers also release their own flashing utilities. It is important to study the characteristics of your tablet and find the right software.
Important: find the firmware version that exactly matches the hardware properties of your tablet. Otherwise, the gadget can be destroyed completely.
Hardware solution
Sometimes using software methods to save the device does not work at all. Then the only solution is to completely change the main board with all the chips. As a rule, it can be ordered in online stores (most often in Chinese). If you are confident in the directness of your hands and have the necessary equipment (you are unlikely to cope with a simple soldering iron with a wide tip and a screwdriver), then you can carry out the procedure yourself. It will cost incomparably cheaper than buying a new tablet.
Users who are not confident in their abilities can contact service centers. Yes, there the procedure will be somewhat more expensive. But you will have to wait less, and the repair will be carried out with high quality. And also cheaper than buying a new similar tablet.
Yes, your personal data and settings will inevitably die. But (see above) they can be restored through cloud services or simply manually.
Important - how to prevent such problems from occurring
If you want to be ready for such problems and get out of a difficult situation without loss, we advise you to do the following things:
- Turn on data sync for all accounts you trust, primarily Google. Activate photo backup on Google+ or Facebook. By default, photos are saved in hidden albums that only you can see. If something goes wrong with your device, you can recover all your data after restoring it (or buying a new one).
- Back up your apps regularly, preferably to a memory card or even to the cloud. We recommend the Titanium Backup application, which can save not only the applications themselves, but also their settings and data, as well as send copies of them to the Dropbox server. Moreover, we advise you to buy a licensed copy of this application: in case of problems, it will pay off.
- Do not clog the memory of the tablet. Try to install only the most necessary applications and games, and if possible, install them on a memory card. When choosing a card, pay attention to at least class 10, and preferably UHS-I. Only such cards will provide you with decent speed. We categorically do not recommend saving on trifles and buying class 4 cards.
- Protect the device from physical damage. The advice is no longer new, but never superfluous.
In our world, people can no longer imagine life without a smartphone. It has become an extension of our hand. For most, the breakdown of your favorite gadget will cause panic and hysteria. This, of course, is not very good, but we have to put up with it. Modern mobile devices are very capricious things. Sometimes they behave unpredictably. In order not to be left without communication, you need to know what to do with the device if it suddenly "bucks up" and does not react to the user's actions in any way. The most common problem with gadgets is that the phone does not turn on beyond the splash screen. What to do in order to revive your "pet"? Let's try to answer this.
Possible causes of failure
There are several reasons for this behavior of the smartphone. And depending on them, the decision to repair will be made. The first (and most common) reason that the phone does not turn on beyond the Android splash screen is a failure during the installation of an operating system update. This happens, because the Android OS is not very stable. It's still half the trouble. However, the same result can be obtained after the device falls from a fair height. It's much worse.
Also common causes may be a malfunction of the battery, charger, or the connector itself for charging the gadget. Now we will analyze, further screensavers. In most cases, you can fix everything yourself. Fatal breakdowns are extremely rare. But at the initial stage, the main thing is to correctly diagnose the problem in order not to make mistakes in the future.
System failure
It's the safest thing there is. If the operating system crashes, you need to enter the recovery mode and reset the factory settings with clearing the cache. Be careful! After this procedure, there will be no third-party application installed by the user. You can enter the recovery by holding the volume up button and the power button at the same time. True, for different models of devices there may be different combinations. Then you need to go to Wipe data and factory reset and confirm your choice. Then you need to mark Reboot system now. after that the phone will reboot. If everything is fine, then the reason that the phone does not turn on beyond the Lenovo splash screen was precisely a system failure.
Sometimes factory reset doesn't help. Then there is another option. You just need to reflash the phone. It's not that hard to do. The web is full of instructions for each specific smartphone. And on any adequate forum you will be happy to help implement your plan. You shouldn't be discouraged.
If the cause is the battery and charging
You can check this very easily. It is enough to find somewhere a similar battery and a similar charger. If, after replacing all the components, you did not see any changes, then the reason that the HTC phone does not turn on beyond the splash screen is much deeper than you thought. There are only two options here: a breakdown of the charging socket or the board itself.
Dealing with a faulty battery or a "buggy" charger is easy. These are not particularly expensive smartphone components. They can simply be replaced with new ones. The problem with the hardware board will be much more noticeable. Here already (in most cases) you can not do without a visit to the workshop. Sometimes you have to pay a very tangible amount for repairs.
If the reason is the board and hardware
It is very difficult to do something with this on your own. You need to have certain knowledge in radio electronics and own the appropriate tool. If you have all this, then you can easily solve the problem. But if the phone does not turn on beyond the splash screen due to a faulty board, and you do not understand anything in this matter, then it is better to take the gadget to a service center. For by arranging repairs on your own, you risk turning your device into a dead brick.
You can try to find a familiar smartphone hardware repair specialist and save on repairs. Only it is unlikely that he will reanimate your device for free. Only if it's a very good friend. But, in any case, you will have to spend money on "magarych". And it is not known how much this will result in.
Summary
Now you know the main reasons behind the screen saver. There are ways to deal with this unpleasant phenomenon. Unless it's a hardware issue. But, as statistics show, in most cases, such a problem is caused precisely by the failure of the operating system. And to eliminate this annoying misunderstanding is very simple with a few buttons.
4 years ago
Hi all. Today I would like to analyze all the most common reasons why an Android smartphone may not turn on. I will not touch on those situations when you need to disassemble the phone and interfere with the electronic stuffing, since this is the work of completely different specialists.
If your smartphone or tablet suddenly stops turning on, it is not necessary to immediately run to a service center or workshop and send it in for repair. Most likely, there is a chance that you can manage on your own and save some money (home accounting programs for Android will also help you save, look for them on the blog). Below we will consider the main measures that can be taken if an Android smartphone or tablet does not turn on. And so, let's get started.
Android phone does not turn on. 5 ways to solve the problem.
Method number 1
From my own experience I will say that in 80% of all cases, if they come to me with a problem that the phone does not turn on, the whole thing turns out to be a dead battery. And I perfectly understand when they tell me that they charged the smartphone all day, but it still does not turn on. Some devices have one unpleasant feature - if the battery is very much discharged, it will not charge, even if you support it on charge all day.
In this case, a frog-type charger will help us, which allows you to charge almost any battery directly by removing it from the phone. It is enough to recharge the battery in this way for 15 minutes. After that, insert it back and put the phone on charge as usual, everything should be OK.
If getting a frog is problematic for you, then you can use any old mobile phone charger. Cut off the old plug and protect the wires.
Make sure that the charger is not connected to the outlet at this time.
We fix the bare wires on the battery with adhesive tape for a few minutes.
Important. Do not reverse polarity.
Method number 2
Faulty charger. Of course, the second thing to check is the health of the charger. Everything is simple here - we take a known working charge and try to charge our smartphone. If the process has begun, then we buy a new one and rejoice. Although it sounds trite, it helps every fifth person.
Method number 3
If the phone does not turn on, then it may just be frozen. To revive your device, we use a long-known, but still relevant method - take out the battery and insert it again.
Unfortunately, this technique does not work on many modern phones with a non-removable battery. In this case, to reboot, you need to find the reset button and press it, for example, with a paper clip. It can be anywhere, but is usually located near the SIM card slot or on the back of a smartphone or tablet. Near the reset button, sometimes there is an inscription reset or off. The photo below is an example of the location of such a button in a smartphone.
Method number 4
This method is applicable if your phone does not turn on, but does not turn on completely. For example, it hangs on your Android logo and nothing else happens. This happens due to a malfunction in the software of the smartphone. Then a hard reset or, in translation, a hard reset will help us. It is done differently for each device model. In order to find out how, enter the name of your phone and the words hard reset, for example LG G3 hard reset, in Google or Yandex and follow the instructions. In the future, I hope to create a separate section on the blog on this topic.
Unfortunately, not all smartphones support hard reset, it depends on the recovery installed in the device. If you are interested in learning more about what it is, look on the Internet.
For example, there is no such function by default in many Sony phones, but the manufacturer has provided the ability to restore the software using a special Sony pc companion utility.
Method number 5
Not often, but it does happen smartphone does not turn on due to the fact that the contacts under the battery do not reach. To fix this, you need to bend the contacts with tweezers or a small screwdriver to improve the connection to the battery. The main thing here is without fanaticism, otherwise you will only make it worse.
If none of the methods helped and your phone still does not turn on, then the problem most likely lies in the hardware itself and only a service center can help you.
Sincerely, Ivan Derbenev.
