How to fix Android stuck on logo screen on Samsung Galaxy S, Galaxy Note, LG G, Moto X, Nexus and other Android devices

Some of our readers have asked us about solutions to download problems on their Android. This is one of those things where you get stuck with a phone that you can’t do anything on, so it won’t even start. This issue is one of the most annoying Android issues, and it can be tricky enough to work on a phone that won’t turn on. You do not have access to your device’s system settings. Let’s check the main prerequisites and solutions for Android download problems.

When download tasks appear on your Android, it can be one of the following:

  • The device does not start at all, it does not charge when you connect the device to the charger, but it is recognized by your computer when you connect it to the computer.
  • The device cannot start, but when you connect it to the charger, you will see that the device is charging.
  • He starts to cut himself in only to get stuck on the loading screen. It can get stuck on the logo screen or it can automatically shut down after achieving a certain point.
  • When you see an error message on the boot screen and the device does not start.

Some users like to expand the capabilities of their own Android device using a custom ROM or working with system files. When your device indicates boot errors, the system files are unstable so that they are corrupted or fiddled with. This is why it is best to avoid fancy ROMs, especially if you are not technically inclined.

This article does not provide solutions for custom ROMs, so there are a lot of things in custom ROMs that can go wrong, which is why our article focuses on the dilemmas faced by non-rooted devices.

Try pressing the power key again

I know you have already tried using the power button, but try it 2 or 3 times as much as possible. After charging the phone, press the power key several times to make sure that there is a certain problem with turning on the phone. If it is on, check if the power key is working properly. There might be a problem with how the power key is connected, and there might be a problem with any loose component. Take the phone to a technician who can check the internal wiring of the phone if the power key is not working properly.

Samsung Galaxy does not cut in or boots up to the inscription “Samsung”.

  • Solution to the problem: Open the back cover of the phone, take out the battery, SIM card, flash card. Put back all the details. Try to enable. If the discrepancy remains, we run over to the next point.
  • Try to charge your phone.
  • THE MOST WORKING AND PROVEN Method (!) Press the combination of the following buttons: Volume control (up) Power button Main menu button. Hold this key combination at one time (about a minute) until the technical menu lights up or the operating system update starts.

Hard reset

The first thing to do when you encounter this problem for us is to try performing a soft reset, which should help you restart your phone without getting stuck on the logo screen. A soft reset is device dependent. While traditionally this requires you to hold down the Power key for 8-10 seconds, there are certain phones, such as the HTC One, Samsung Galaxy Tab 3, and Sony Xperia Z3, that require you to hold down the Power and Volume up keys for 8-10 seconds. Depending on your phone model, one of them might be successful.

Reasons why Samsung won’t get it right or stuck on the logo screen

If Android does not load on the phone or tablet when it is turned on, or the Droid phone starts up, but does not go beyond the logo splash screen, then the prerequisites for this may be as follows:

  • Errors when flashing the device. These include the installation of an unsuitable or warped assembly, a violation of the firmware order, a power failure and other factors.
  • Out of memory.
  • The system may not start or boot extremely slowly due to insufficient memory.

The solution may be to optimize applications and remove unnecessary data. Memory card incompatibility.

Let’s talk most thoroughly about these and other problems that can become a prerequisite for this problem.


We are all accustomed 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 are faced with in a particular case.

So if Samsung A 20 won’t boot or freeze when turned on, the best and easiest way to resolve the issue is to restart your phone.

Have you tried restarting your device but it didn’t work? Then repeat it five more times. Getting the system to boot normally is not easy, but multiple reboots in the vast majority of cases are successful.

You can also try simultaneously holding down the Home button, as well as the power and volume keys. Some Samsung models, including, 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 bringing the phone back to life, which we will consider next.

Hard reset

If an elementary reboot did not help, and still Samsung A 20 does not turn on or does not load beyond the screensaver, you need to resort to more radical measures. The best option is to reset all settings, or, in other words, Hard Reset the phone. It is quite simple to do this. 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 holding down the power key for 10-15 seconds.
  • We simultaneously hold down the power and volume down keys. You can do this with one hand, but we recommend using both. There have been cases when, through carelessness, 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.
  • Operating with the buttons to decrease and increase the volume, select the item “Wipe Data”. It involves deleting all data and settings from the phone. Thus, whatever the software problem is, most likely you will fix it.
  • The system will ask you whether you really agree to the deletion of all data. Confirm the action and wait about a minute. Next, you agree to reboot the device and wait for the updated software to download.

If all systems start up normally, and the phone is functioning as it did before the problems occurred, then congratulations. you have found a relatively simple and painless way to resolve the issue. If the phone still does not turn on, or the download does not go beyond the screensaver, it remains to resort to the third method.

Samsung A 20 phone freezes on splash screen and won’t turn on

The Samsung A 20 phone is one of the best options for budget gadget lovers. 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 face technical problems.

Many are worried about the question: what to do if the A20 does not turn on? And what if Samsung A 20 does not turn on and freezes on the splash screen? Many users of this gadget have encountered this problem. Since it is very common, we suggest that you familiarize yourself with the main options for its solution.


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 a 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, a firmware change works.

First, download the firmware to your computer, and then drop it onto 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, holding down the power and volume buttons. If there are installation files on the memory card, then the system will recognize them by offering you the following item: install zip from sdcard. This is exactly what is needed if the phone turns off and we need to change the firmware. Confirm the actions by starting the file upload.

Flashing usually takes a few minutes. Do not be alarmed if the phone goes off during the session. 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 a thing of the past, and now you know how to turn on the phone, which began to slow down, or does not turn on.


The real trouble begins when system files are damaged. They can be restored by reinstalling Android, but erroneous actions can change the situation for the worse. Of course, in this case, there are chances to “revive” the phone, but if you are not interested in such prospects or Samsung is still under warranty service, it is better to immediately contact the service.

On the other hand, things are not that complicated. There is a special program. Odin, which only works with Samsung devices. All actions are performed on the computer, and the device itself at this time must be in a special boot mode. The reinstallation process and preparation for it are described in detail in the step-by-step instructions published on our website. There are also several examples of flashing the system for specific models of this manufacturer.

Battery charge

Connect your phone to a charger (preferably an original one) and wait 20-30 minutes. It is normal if, after a complete discharge, the smartphone connected to the mains does not have enough power to turn on for the first time. If you can’t directly charge, connect Samsung to your computer’s USB port.

Inspect the cable for damage. If possible, try charging another phone with it, or use a second charger.


If the Samsung smartphone does not start, the manufacturer recommends making a forced reboot. To do this, simultaneously hold down the power and volume down buttons for 10-20 seconds.

On a device with a removable battery, open the back cover, remove the battery, then insert it and try turning on the device again.

For some users, the phone started working after removing the SIM card or memory card, which turned out to be damaged. It is not difficult to check this version, and if it works, it will be possible to avoid more radical measures.

Troubleshoot Samsung device startup problems

First of all, make sure that the smartphone does not actually turn on. For example, when the matrix is ​​broken, it continues to work, but the screen remains black with no visible damage. As a test, make a call to it from another device.

Clearing the cache

This option clears the temporary storage partition. Every installed application leaves a cache in the device memory, and this can become the source of the launch problem. We have already written in detail about clearing the cache on a Samsung smartphone via Recovery Mode.

Recovery Mode

“Recovery Mode” is a dedicated boot partition. Its main task is to delete user data and files, reset settings, and update Android when there is no way to do it from a loaded system. This is an effective and safe way to get your Samsung smartphone back on track. Depending on the model, the key combinations for entering Recovery Mode may differ:

    If the mobile device has a “Home” button, we clamp it together with the power and volume up buttons.

If the smartphone has the “Bixby” button, hold it down simultaneously with “Volume up” and “Power”.

On devices without physical buttons “Home” or “Bixby”, just hold down “Power” and “Volume up”.

“Safe mode

Make sure the operating system does not conflict with the software. To do this, boot Android into Safe Mode, which disables all custom applications. This option is possible if the phone starts to turn on, but does not finish, but freezes, for example, on the screen with the logo.

At the bottom of the screen will appear the inscription “Safe Mode”.

If the download was successful in the BR, then you need to look for software that prevents the phone from working normally in normal mode. You can start with recently installed applications. Despite the fact that the third-party software is deactivated at this moment, it still remains in the system, so it can be removed using the method described in a separate article on our website.


After resetting data from the phone, contacts, messages, installed applications, etc. will disappear. This option returns the device to the factory state. However, some of the data can be recovered if synchronization with a Google or Samsung account has been enabled on the device. It will then be enough to log into the same account on this or a new smartphone.

The reset procedure is performed automatically after selecting the desired item in Recovery Mode. The complete algorithm of actions is described in a separate article on our website.

Samsung Galaxy turned off and won’t turn on. reasons

If your Samsung has turned off and won’t turn on, it can damage the operating system, but this happens very rarely.

Much more often the reason is in the battery. Of course, the first thing you do is connect the charger and nothing happens.

You are confident in the outlet, in the cable, in the charger itself and in the contacts in the smartphone socket. Check these things and make sure they are not the cause. It happens that the contacts on the battery are out of order, and this leads to the fact that the phone does not turn on.

In this situation, it can be very helpful to remove the battery and clean out the old contacts that connect to the battery.

Removing the battery will also reset the phone somewhat. The above method is only for smartphones with a removable battery.

Also pay attention to the power button itself. it also does not last forever, although it does not break often, it does happen. If none of the above turned on the phone, then the problem may be inside the Samsung Galaxy phone. in its components.

Defects are a common and well-known problem with smartphones, which we use almost without interruption and have become indispensable for us.

They are susceptible to numerous failures: it turns off and does not turn on, does not turn on and does not charge, turns off and spontaneously turns on, turns on and off immediately, after the update the screen does not turn on or constantly reboots. this is how both a smartphone and a push-button can behave.

What to do? Before heading to the service, try my options below, and whoever is friends with a soldering iron can even get inside. I also intend to describe such options. Go.

Your Samsung Galaxy smartphone won’t turn on yet. see what’s going on inside

Mobile devices, which work much like computers, have periodic defects that we often don’t notice. Worse when our phone won’t turn on and we don’t know how to fix it.

The answer to the question is very simple. All you need to do is go to the service, unfortunately, this is not always possible.

What can we do to avoid high post-warranty repair costs? I will advise you on how to diagnose your device.

My Samsung Galaxy A20, A10, A50 won’t turn on or charge (Resolved)

Although the activity may seem very simple and obvious, but not everyone succeeds, and the first thing to do is to disconnect the battery.

Removing the battery and cleaning the contacts (connecting to the battery) in your phone can help.

Very often the smartphone has rusty contacts. Of course, many Samsung phones today have a non-removable battery. Then skip this step.

Removing the battery allows you to reset the phone. The second step is to view the charging connector.

It is worth looking into the connector, illuminating with a flashlight, to see if your plug is damaged from charging.

In addition to checking the outlet, remember that the battery can also be the reason the phone won’t turn on.

The next step is to connect your phone to your computer by plugging in a USB cable. If a window or “Install Driver / Software” appears on the computer, the Charge Controller may be damaged.

What to do? This is a little more complicated. In phones, it is often soldered to the motherboard, but there are also models in which it is a separate module.

You can try to replace the connector yourself, but if you are worried that repairing your smartphone will be overwhelming, then it is better to leave this business right away.

You can also see, for example, if the contacts have slipped off the display. This happens most often (although this is a very rare occurrence) when the phone is dropped.

Removing the cover will allow you to check for damage. If the connector on the display is connected correctly, then you need to look for the problem somewhere else.

One of the common malfunctions in our device, when the phone vibrates in our hands after pressing the “Power” button, but the screen does not turn on.

Even then, it can be determined that the defect is on the display side, and not on the charging connector or other components.

Worst of all, if the motherboard is damaged. this is the heart of the phone and does not bode well.

Even the service does not undertake its repair. based on the profitability of the repair. If none of the suggestions above work, then the motherboard malfunction is almost certainly.

The repair costs in this case may be greater than replacing the display. Also, you should remember that there are data recovery companies in the event of damage to the motherboard. Success.

samsung, turn

Let’s figure out why the Samsung phone won’t turn on. First, we will list the main reasons, and then we will give an explanation for each of the points.

How to fix Samsung Galaxy A20 that won’t turn on

Smartphone updates

Probably all users of modern devices like to experiment with updates of various applications, but they forget that not all updates are useful for smartphones. Some downloaded features go against the system of the device. this leads to the fact that it will turn off when it pleases.

Exit: from the switched off phone, remove the battery, wait a few minutes, insert the battery, turn on the device and remove unnecessary updates. If this does not help, you will have to apply a smartphone sweep. Wipe is a function that removes all settings from the phone and returns it to the factory settings.

OFF / ON button

Sometimes it is because of this button that the phone has a dark screen. When the device is completely new and the on / off button is faulty, get acquainted. this is a factory gaffe. Contact the seller who will change the phone or redirect to the service center.

If the device has been serving you for some time, and it suddenly became clear that the screen image is not loading, take it for repair. Such a problem could have occurred as a result of the impact of the phone or moisture that got into it. The service will offer you the following services:

  • keyboard panel replacement
  • deep cleaning of the device
  • partial or complete replacement of the keyboard controller

Charger status

You put the phone on charge, the required time has passed, but it has not turned on. Pay attention directly to the charger. In the device, the wires may break off or the contact may come off.

The way out is as follows: take a similar “charge” or use the “frog” battery. If these methods do not help, remember if you have charged your smartphone using someone else’s charger, which may not fit your mobile phone. Expensive phones are very sensitive to such changes and, after that, only a flashing can save them.
