The phone does not see the SIM card, what should I do? Why is Android not updating? How to force update Android? Updated android app not working
IN modern world You can't imagine a person's life without a phone. Every person has this little helper. It makes it easy to contact the desired subscriber. But imagine that your Android phone does not turn on. What to do in this case? Of course, without a smartphone it will be quite difficult. If you do not have a spare gadget, then you need to quickly fix your device. In this article, we will look at why the Android phone does not turn on.
Mobile check
If the phone has stopped turning on, then you should not immediately disassemble it and see what could happen there. Of course, if you do not have certain knowledge, all these actions can be disastrous for a smartphone. Subsequently, repairs can only become more difficult and costly. Why won't my Android phone turn on? What to do in this case?
Before proceeding with cardinal actions, it is necessary to check - maybe it did not break at all. First, you should find out if the battery is charged, or maybe the reason is a software failure of the device.
Mobile device battery check
As we have already found out, the phone may not turn on due to low battery. We put the smartphone on charge and wait about 30 minutes. After that, we try to turn it on. If the phone was able to "revive", then the problem is high charge consumption. How can this be fixed? It is enough to turn off Bluetooth and Wi-Fi after use. These elements are constantly working to find a possible network in order to inform the user about it. If you turn off these elements, you can save a charge for a longer period. You should also reduce the brightness on your smartphone, as a bright screen consumes a lot of energy.
If you have a function on your mobile phone that allows you to change the brightness automatically based on the room illumination, then you should turn it on. Let's get back to the problem. If the phone was able to turn on when it is charging, then let it stand for about 4 hours. It is worth checking the expiration date of the battery - it may be time to change this component. If the phone does not turn on, but the Android is charging, you need to consider other possible situations.
Smartphone power button
The phone may flash but not turn on. This may be due to a malfunction of the power button. The reasons why it may not work may be different:
- If you have just purchased mobile phone, and it does not turn on, the power button may be faulty, and the reason lies in the factory marriage. What to do in this case? You need to contact the store where you purchased the smartphone and ask for a refund, replacement or repair of the phone. The seller must do something in this case.
- Another reason is also possible, which is already associated with your carelessness. If you spill liquid on your mobile device or drop it, there may be various reasons why the phone will not turn on. In this case, do not disassemble the device yourself. Of course, if you have a warranty, you can try contacting a service center. Otherwise, you will also have to resort to the help of a professional. Unfortunately, even he is not able to fix any phone.
Memory card
So, your Android phone does not turn on. What to do? The reason may lie in the SD card. Your phone may not support a particular memory card, causing the mobile device to freeze or not turn on at all. You should choose a memory card in specialized stores, having previously learned that it will fit your smartphone. If different memory cards cause the same effect, then the problem is in the phone. In this case, you need to reflash the mobile device. You can do it yourself, but you should be careful, as you can only do harm.
Phone won't turn on after Android update
Sometimes situations happen with smartphones when it does not turn on after the update. As a rule, new gadgets are more prone to this. Various updates come to the mobile device, which, unfortunately, are not safe. Usually smartphones that have constant access to the Internet are affected by this. After such updates, the phone may randomly turn off and turn on after a while.
Another situation is also possible: you are trying to turn on your phone, and Android lights up there and nothing else happens. Reboots bring the phone back to this problem again. So, your Android phone does not turn on again. What to do? In this case, it is worth trying to turn off the device and stick out the battery for a few minutes, then turn it on and reset the settings. If the problem was not serious, then you will succeed, and after a while the phone will return to its previous state.
If it refuses to work adequately, then you should use a hardware reset. This will clear your phone of updates and all information. But, most likely, it will return to working condition. Of course, all personal information will disappear from you, but returning the phone to its former life will probably be more important. This reset will be done differently for each smartphone. You need to find the right way for your model. Phone won't turn on after factory reset? "Android", unfortunately, may not be suitable for such a solution. In this case, you will need to reflash your device.
After flashing the phone does not turn on (Android)
If you unsuccessfully flashed your device, then it may not turn on or hang on the Android logo. What to do in this case? Of course, you will have to reflash again.
First, we go to the manufacturer's website and look for the necessary firmware that will fit your model. You should not look for firmware through a search engine, as it will give out many different programs that, most likely, will not work. So you can only aggravate the problem and bring your smartphone to a “brick” state.
After the firmware, the phone does not turn on. "Android" can still be brought back to life. You will need to properly install the new firmware. If you do not know how to do this, then you need to contact the service center. So you can be sure that everything will be fine with the phone.
Mechanical damage
The most common cause of smartphone failure is mechanical damage. If the phone has been dropped or you have spilled liquid on it, then this is already a serious problem that cannot be dealt with so easily.
If the fall was not serious, then you can try to stick out the battery, SIM card, SD card. After a while, we return everything to its place. If the phone worked, then you were lucky, and his contacts just went away. Otherwise, the problem is more serious. If you do not have the necessary knowledge, then you should not try to disassemble and repair the mobile device yourself. In this case, contact the service center.
The devices are very simple. All you need to do is go to the settings, click the appropriate button and wait for the work to complete. However, no one is immune from all sorts of mistakes at the initial or final stages, therefore, in order to minimize possible problems We offer you some tips.
Data backup
This is a necessary thing that everyone keeps talking about: backup, backup, backup. The more copies you have (and the more often you do them), the later (in case of emergency) will be better. You can copy files the old fashioned way to your computer, or you can trust various cloud services.
Charge your device
Although the corresponding warning pops up during the update, not everyone takes it seriously. Often, when the battery is low, updating simply will not work. In any case, it is very important to have enough charge in your smartphone before starting the update process. We recommend having at least 70% or 80% in reserve.
Take some screenshots of your desktop
In most alternative launchers, all settings are usually backed up automatically. The stock solution does not provide such a function. When you upgrade, you will get the same set of icons and widgets on your desktop (but it's better to be safe anyway), but if you decide to install the firmware from scratch, then in order not to remember the location of the elements later, you should take a couple of screenshots of the desktop (and send them to your mail, for example).
Clearing the cache
Clearing the system partition with the cache after installing any updates is a holy cause. This is the easiest and surest way to avoid battery and performance problems at the initial stage.
To do this, turn off the device, press the volume keys and, without releasing them, the power button. After pressing the volume down button, select the "Recovery" option. Press the power button to confirm the action. After the device reboots, hold down the Power key and press and release the Volume Up button. Finally, use the volume down button to select the "wipe cache" option. Press the power button to confirm the action. Now it remains only to wait a few minutes. At the end of the process, the device will ask you to reboot.
We cannot guarantee that the new version of Android is free from bugs, but typical problems with random restarts and incorrect behavior of some applications can be completely eliminated using the above procedure.
What troubles happened to you during the upgrade process? Let's help others avoid similar mistakes!
According to AndroidPit
The article describes how to update Android.
If we take into account the statistics, then already in 2013, most of the smartphones purchased by consumers worked on the platform " Android". In addition, various manufacturers of such gadgets (except " Nokia" And " Apple"") by default install on their devices the operating system " Android».
Many factors, including being free and having many games/programs, have made this OS extremely popular. In this article, we will briefly talk about how to properly update " Android» to newer versions.
About Android
operating system " Android"in fact, it was not originally developed by the company" Google". Authors operating system for gadgets tried to distribute their creation through the company " Samsung”, which, in turn, refused this offer. But " Google» seen in « Android» great prospects and acquired the rights to this development.
The first gadgets on the platform " Android”, which went on sale a few years ago, have not yet made a splash on the market, the new operating system has so far been, so to speak, in its “raw” form. But after five years Android» gained immense popularity among consumers, pushing into the background « Windows Mobile" And " Symbian».
Now available to purchase Android 6.0”, although it is possible that tomorrow there will be newer versions of this OS with bug fixes. That's all well and good, especially when setting " Android from scratch or buy a gadget with a fresh version. But how can you be sure to update to new versions without any problems?
How to update "Android" to new versions?
First of all, you need to know:
- Before updating the operating system, the battery on your gadget must be charged up to 100%
- Before updating the operating system Android» all your programs, contacts, information, etc. must be stored in a separate location. Often, after updates, all information can simply be lost.
In total there are several options for updates " Android» to the latest versions:
- Auto
- Forced automatic
- Using a computer
Automatic update method is the most popular. Operating system " Android» itself looks for updates, and when they come out, the operating system « Android" prompts you to download and install them. The user is only required to give their consent.
By the way, updates weigh quite a lot, up to several hundred megabytes, so with your limited Internet traffic, it is better to use Wi-Fi, if available.
Forced-automatic method can be called semi-manual or semi-automatic. If the operating system Android» is not looking for updates on its own, then this role is assigned to us. To do this, go through your gadget to the Internet, open in your smartphone " Settings", then click on the item" About the system» and enable automatic search for updates. The menu should have a button System update". If updates have already been released, the smartphone will prompt you to download and install them.
It can be seen from these instructions that the update " Android' is a fairly simple process. But there are also problems. The system may refuse to download new updates. In this case, you need to reset the settings and try to download the updates again. In 90% of cases it helps users. If this does not work, then you will have to turn to another method of updates - through a computer.
Update using a computer happens using custom firmware. Custom firmware are unofficial updates. The fact is that any updates of any system can be both official (that is, created by the developers themselves) and unofficial - updates made by individual programmers. In custom firmware, as a rule, everything unnecessary is removed from the point of view of certain user groups and, accordingly, everything necessary is added according to the same criteria.
The whole point of updating the operating system " Android»on a gadget through a computer is as follows. You need to download the firmware from the Internet to a computer, and then from the computer using certain programs, download and install it on the gadget. But this is a relatively difficult process. It must be remembered that each model of a smartphone or tablet has its own procedure (selection of custom firmware, installation programs, etc.). You can learn more about this for your gadget model on the Internet.
Video: How to update an Android smartphone?
Surely you have heard about the Android operating system, unless you yourself own a device running this shell. This platform was liked by a good part of gadget owners and is the most common operating system among mobile devices. Since 2009, when the first version of the "robot" was released, the developers have not stopped improving and modifying their brainchild. New versions and updates are released regularly. But is it always necessary to update your device and how to return old version"Android" after the update? We will talk about this in this publication.
Why are updates needed?
First of all, for the correct operation of the system. Developers optimize performance, improve the interface, fix lags, because it is practically impossible to release a perfect system right away, and minor malfunctions will be noticeable only during its active use. In most cases, you can find out about an update using a regular message that will appear in the notification bar. You can upgrade by going to the update center, downloading and installing the new version.
Why might gadget owners be unhappy with the update?
In most cases, after the update procedure, the device should work faster, and all the flaws should be a thing of the past. All that users can complain about is some changes in the interface or, for example, the disappearance of shortcuts from the desktop (accordingly, the applications themselves disappear). This happens because installed programs are already outdated and simply do not correspond to the new firmware.
New versions of applications or their analogues can still be found on the Play Market, and trying to return the previous version of the OS due to the loss of old applications is a rather stupid idea. What else can annoy owners in new version firmware - so this is the appearance of some programs that cannot be removed. For example, it can be new services from Google. And then users without exception begin to think about whether it is possible to return the old version of Android. But most of all those who want to return to the old firmware are among those who tried to reflash their device on their own. Here, a huge number of problems may appear, up to the point that your gadget can turn into a "brick", that is, generally stop showing signs of life.
So before performing such manipulations, make sure that you have enough knowledge and experience, and best of all, contact a professional. Reflash the device only in extreme cases, when you cannot do without it, because such a procedure completely deprives you of the warranty. But you can still return to the previous version.
How to return the old version of "Android" after the update?
To begin with, come to terms with the fact that the standard resources of the system do not provide for the option to roll back the system, as, for example, in the Windows OS. Accordingly, when you return to the old version, all installed programs and personal files will be deleted. Therefore, just before the procedure for returning the old version, make backup copies of all important documents, files, phone numbers, and so on. Get ready to say goodbye user settings, saved accounts or applications, they will be erased all except the built-in ones.
Next, you will have to perform a factory reset yourself. How to do this depends only on your version of the operating system, but most often this item is found if you go to "Settings" and "Restore and Reset". Also, this parameter can be found in "Confidentiality". In any case, finding a factory reset will be easy. Next, you will need to perform a series of actions a little more difficult, that is, enter recovery. And how to return the old version of "Android" with it - read on.
Login to recovery
"Recovery" is a special boot mode for Android, with which you can reset settings or flash the system. If you buy gadgets in trusted certified stores and with an already installed OS, then they should have a stock "recovery" mode. How to enter the "recovery" depends only on your device model. The most common combination is the power button and the volume down key.
For example, if you do not know how to return the old version of Android to Lenovo, then this combination is suitable for most of their devices. I would like to note that before entering the "recovery", you need to turn off the phone. If you are looking for how to return the old version of the "Android" Sony Xperia, then here you need to hold down three buttons already: those that we have already named, and the camera button. You can easily find more detailed instructions for various models on the World Wide Web. But what to do after entering boot mode?
How to return the old version of "Android" after updating through the "recovery" mode?
You can navigate through the menu using the " highlight", and to select a specific item, you need to press "select". You do not need to be afraid of this mode, if you delve well - it becomes clear that there is nothing complicated. Now find the line with " wipe data / and select it. A new menu will open in which you will have to confirm the action. After - wait for the reboot and the OS will return with factory settings.
Charge your smartphone
What is worth noting in the first place is that before starting this procedure, you need to charge the device well. It does not matter how long the system rollback takes and how much the gadget will reboot after that.
If during such manipulations in the "recovery" mode the device does not have enough charge and it cannot complete its task, then, most likely, problems with its further use cannot be avoided.
The same applies to self-flashing the phone. For some users, certain system functions disappeared or did not work, up to the loss of touchpad functionality. In some cases, the firmware did not start at all and it was simply impossible to enter the OS. But even then recovery rescued again. If you cannot enter this mode or it simply does not exist, there are a number of simple utilities for flashing this mode directly through the "OS". Sometimes you may need a PC for this task.
We told you about how to return the old version of "Android" after the update. Take good care of your gadget and it will serve you for a long time.
