On some phones, users who once turned on RTH rights sometimes encounter such a problem: when they start up, the phone writes the message "Android launch, application optimization" and does not turn on. What to do in such cases? Sometimes you just have to wait, and for a noticeably long time (up to 30 minutes) - until all the planned synchronization has passed, which will subsequently need to be turned off.
If the phone still booted up after synchronization, we recommend clearing the cache. It is in the incorrect functioning of the cache on Android that this problem. The most convenient way to do this is through the installation free application from Google Play Store: Clean Master Lite. This is if, after much thought, your phone still starts up.
Download Clean Master Lite to clear cache Android
If you do not have the Internet at hand or there are other problems that prevent you from clearing the cache through the application, do it manually by starting recovery mode on Android.
1. Turn off the phone,
2. Clamp and hold the "Power" button and the lower "Volume" button,
3. We are waiting for the recovery menu to appear and select the “Recovery” item, using the sound control buttons,
4. Next, the line "No command" will appear in the menu,
5. Click on the "Enable" button and select the item "Wipe cache partition" in the new menu
6. Reboot the phone by selecting "Reboot system now".
If the steps described in this guide did not help and the phone still says: "Starting Android, optimizing the application" when it is turned on, and it does not start, a factory reset procedure will be required. It will affect the data in your phone - remember this. So create early backup the contents of your phone.
If it suddenly happened that your favorite phone or tablet suddenly and unexpectedly finished its work, then immediately run to the warranty center, or somewhere to the workshops and return it under warranty is not worth it yet. With a minor breakdown, there is a chance to quickly and independently fix some problems and save a certain amount of money. Below we will consider the main methods and measures that can be taken if the Android phone or tablet does not want to start.
Why the phone won't turn on
- Faults charger
- Battery malfunctions
- System errors
- Hardware problems
To begin with, it is worth checking the operation of the charger and connecting a working charger to the smartphone. Everything is elementary here - we buy or ask friends for a working charge in advance and try to connect own phone and check whether the charge is on or not. If the process has started, then we get a brand new charger and continue to use it. It sounds very banal, but according to statistics, it helps every third person. If not, then we look for the problem further.
If your device on the Android system absolutely does not turn on and you do not understand what exactly stopped working in it, then the next thing you need to look at and check is the battery and you will need to reboot the gadget with the battery removed. The fact is that the device may be frozen, but it may seem to you that it is turned off, but in fact it is fully functional and the system simply blocked the screen programmatically and in this state the smartphone stopped its work, this happens due to system errors.
You can fix such difficulties very simply by restarting the device. To fully reset, remove the back cover of your device and remove the battery. After the manipulations have been done, do nothing for about a minute, then install the battery back and try pressing the power button again. Perhaps these manipulations will be enough and it will fully work again.
Advice! If the device does not work after removing and reinserting the battery, connect the charger for a few minutes.
If your device has a closed, non-collapsible system and it is very difficult for you to remove the battery, then read the instructions for your model, usually the manufacturer took into account a special key for forced reboot and restore the system to factory settings. For example, on Sony phones such a key is located under the cap.
Some mobile phones have 1 very bad side - if the battery is completely discharged or the phone has been lying without recharging for a very long time, then it will not be able to charge immediately after connecting the cable, including if you keep the gadget on charge all day.
In this case, a frog-pin charger will undoubtedly help us, which allows you to connect any battery directly, through the contacts on it, by removing it from the telephone. It is quite simple to charge the battery in this way in literally 10 minutes. After the work done, insert it back into telephone set and on charging traditionally, everything is bound to recover.
Difficulties with the insides of the smartphone may appear if you drop it or hit it. In this case, it will be problematic to repair it without the help of others, since the battery could completely fail from the impact, or the system module was damaged. In this case, it is only better to take the damaged tablet or mobile to the service. If you still decide to fix it yourself, then you can find the board diagrams and cable locations on the network in order to diagnose and try to restore the device.
Hard Reset or Hard Reset Android
In the case of software problems or a software failure, it will be much easier to resurrect the device. For full reset nessesary to use standard function hard reset. For all models, this operation is performed identically, but it is better to find instructions specifically for your model. Absolutely everyone can perform a full reset, since this requires only holding down the necessary buttons. First of all, you need to turn off the phone if it freezes at the boot stage. To avoid losing any data, it is better to remove the memory card and SIM card. After the work done, you need to find out the combination with which a complete reset will be performed.
It often happens that the phone does not show signs of life due to the fact that the contacts do not reach the battery and in order to fix it, you need to use tweezers or a small screwdriver to mobile devices bend the contacts to fully connect the battery to the battery. The main thing here is not to overdo it and not make it worse, you can’t ask a friend who knows the tools better.
If you found out and checked all the prerequisites described, but your Android phone never woke up, then it’s more likely a hardware failure or the firmware has crashed along with the bootloader or the memory module has failed. In this case, the telephone must be returned to service center, because without the help of experienced and knowledgeable people you can not do it. Also, for many models, full firmware helps, but this is if the device at least somehow reacts to the power button.
If the Andoid phone does not turn on, then this does not mean that it is broken. It is possible that the problem is not so serious and can be solved without outside help. In this article, we will look at some of the most probable causes, which can lead to problems with inclusion android phone and also tell you what to do in such cases.
Reason #1: The phone is frozen.
If yours is, and you don't know what to do, then the first thing to try is to hard reset your phone by removing the battery. The fact is that it may seem to you that the phone is turned off. Although it actually works, it just locked the screen and hung in that state. It is also possible that the phone is turned off, but something is blocking it from turning on.
You can fix such problems only by completely rebooting the device. To do this, remove the back cover of your Android phone and remove the battery. After that, wait a few seconds, put the battery back in and try to turn on the phone again. It is likely that such a simple procedure will be enough for Android to turn on in normal mode.
If your Android phone has a non-demountable design and you cannot remove the battery, then read the instructions for your model. It is likely that the manufacturer provided a special button for forced reboot. For example, on Sony phones, such a button is located under the cap.
Reason number 2. The phone is discharged.
If your Android phone is completely discharged, then it may not turn on even if you connect it to a charger. This problem is especially common on older phones, in which the battery has already exhausted its life and does not accept a charge well.
In order to eliminate this problem, just leave the phone on charge for a few hours. It is likely that after a while it will turn on without problems.
Reason number 3. Faulty charging.
If your Android phone has been on charge for a long time and still does not turn on, then there may be a problem with the charger. The charger may have failed and is no longer working.
In order to exclude this option, try charging your phone from any other USB charging. If there is no other charger at hand, then you can try to charge the phone from the computer. But, keep in mind that charging from a computer will take longer. Therefore, be patient.
Reason number 4. Software problems.
In some cases, the Android phone starts downloading, but does not turn on until the end. At the same time, the manufacturer's logo or the Android logo may glow on the screen and nothing else happens. This behavior is usually indicative of software problems.
In that case, you can try with recovery menu. But, we will immediately warn you that resetting the settings will delete all data in internal memory(including contacts, sms messages, photos, etc.).
Reason #5: Hardware failure.
If you have checked all the above reasons, but your Android phone still does not turn on, then most likely the reason is a hardware malfunction. In this case, the phone must be carried to a service center, since there is little you can do on your own.
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 boot up completely, even when it is turned on / off repeatedly, only android screensaver, or the zte logo.
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:
- 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.
- Not enough memory. If there is not enough space on the internal or external media It may take a long time for the system to boot. Often in such cases, the tablet or smartphone does not turn on at all.
- 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.
- Complete discharge of the battery. A fairly rare cause of problems with smartphone downloads, but it cannot be completely ruled out.
- 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.
- Memory card incompatibility. Rarely, but there are situations when it is the new flash drive that interferes normal operation devices.
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 above problem 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 recovery menu mode. 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 occurs in unknown reason and this was not preceded by a fall or program 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 will 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. operating system Android 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:
- The smartphone is often completely discharged, and charging is insufficient.
- The phone often overheats.
- System crashes occur after installing updates with insufficient battery power.
- 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.
If problems arise with a wet gadget, do not connect it to the mains and stop pressing the buttons. as soon as possible and only then follow the advice from this article.
If you are sure that the inside of the smartphone is dry, feel free to continue.
