Samsung A50 Won’t Turn On What To Do

Calibrating the Scanner

The module may fail due to incorrect configuration. You will need to delete old data and register new ones.

Note that the fingers themselves may be the problem. If a finger registered in the system has cuts, scratches, thermal or chemical burns, the device will not be able to receive the correct information. Better to register other traces in the system. After registering another fingerprint, it will become clear whether the module is functioning.

Customization can be done using a third party application. It will test the equipment and find out if there is a hardware defect or the whole thing is in the software.

If no messages are displayed on the screen, and the testing instructions are still hanging, the Samsung fingerprint does not work. There is a hardware defect.

Why does the fingerprint work poorly on Samsung A50?

The main reasons for a non-working scanner:

  • contamination of the screen, which prevents the sensor from receiving the necessary information. In addition, screen protectors or glass can also affect sensitivity;
  • unsuccessful update of the module;
  • poor quality calibration;
  • breakage or mechanical stress.

All of these reasons can be equally valid. Let’s figure out in more detail what actions can be taken.

Incorrect Samsung update

Samsung A50 Won't Turn On What To Do

Owners of the A50 often complained about the slow performance of the scanner. The procedure for passing the protection took too much time, sometimes the sensor would freeze and one had to apply a finger several times. The manufacturer offered users an update that should fix the problem. Unfortunately, after the update, many Samsung A50s do not have a fingerprint, as before. In addition, the situation has worsened.

The manufacturer recommended re-registering prints. deleting old data and registering new ones. Not everyone was able to carry out the procedure to the logical end. In some cases, the process would freeze at the very beginning. In others, it failed. Those who were able to re-register faced another problem. after some time the sensor stopped seeing prints altogether.

To solve the problem, it is recommended:

  • do not re-register;
  • if it has already been done, roll back the system to factory settings.

Through experience, users have come to the conclusion that the problem can be solved by re-registering the same finger in the module.

Wipe the sensor

The screen of the gadget goes to different places every day, collecting all the dirt. Few owners wash or wipe the device daily. However, gadgets also need hygiene. To clean up:

  • a piece of scotch will help. Cut a piece to the size of the scanner, stick and press firmly, remove with extreme care. This method will help remove coarse dirt and accumulated grease;
  • Use damp baking paper (used for baking) to wipe the touchscreen
  • an alcohol or specialized wipe will help remove grease, dirt and the most stubborn dirt. Don’t rub the screen hard.

Dry the scanner thoroughly after cleaning. Hands should also be clean and dry. Check sensor functionality.

What to do if the fingerprint does not work partially or completely?

Of course, you shouldn’t blame everything on an incorrect update. The fingerprint touchpad may not be working for another reason. A number of actions should be taken. Perhaps some of them will improve the performance.

Fingerprint works poorly on Samsung A50. what to do?

Some owners of Samsung A50 note that the scanner, which is supposed to protect the device from unauthorized access, is too slow. Sometimes the module only responds after a few finger taps. The manufacturer has released an update. The scanning device was expected to be corrected. But the problem when the fingerprint does not work well on the Samsung A50 remained relevant. In the article we will talk about what reasons can lead to module failure, its poor performance and what can be done on our own.

Replacing the fingerprint scanner

If the smartphone has just been purchased, but there are already problems with the pattern recognition sensor on your finger, you should immediately take it back. If Samsung A50 has been in operation for more than one day, the efficiency of the module may decrease. In this case, it may need to be replaced. Considering that the recognizer is not push-button, but touch-sensitive, the cost of repair can be high.


If you are trying to charge the phone from a computer device, or using the standard method through an outlet and the Samsung phone does not work, then the reason for this may be a faulty cables. First of all, you need to carefully review all the cords on the phone. If you checked, and they turned out to be intact and working, then the reason is not in them. It is necessary to continue to look for the reason.

The reason may be:

  • It is quite probable that the connector itself is not fixed in the phone. If this is true, then it will need to be replaced;
  • In the event that the same connector is slightly torn out of the so-called printed circuit board, the phone will also not charge;
  • The food controller may be broken. In the event that this is indeed the case, then it is necessary to replace it;
  • If the phone takes a long time to charge, it indicates a damaged power circuit. This detail is quite essential in the entire system, therefore, it is necessary to carry out diagnostics before its direct repair;
  • A small enough percentage may account for other problems.

It is also very likely that the problem is that the phone is quickly discharged, but very slowly or does not charge at all. Then the problem is in the battery itself.

Such problems are quite common and people do not know what to do in these cases. Therefore, we provide a solution to problems.

Why Can’t Charge Your Samsung Phone

Unfortunately, today, people who own Samsung phones suffer from the fact that the phone does not charge or charges, but with great interference. This problem has recently become quite common.

This article is for those people who also encountered this problem. If this problem is detected, it is necessary to immediately take the necessary measures, because this problem cannot be left to chance. Further in the article we will take a closer look at why this happens to the phone (does not charge) and what to do in such cases.

Elimination of breakage

First of all, it should be noted that if the problem is not in the charger, then it is best to contact a specific service center. There they will quickly carry out the necessary diagnostics and determine the cause that you could not determine.

In many centers, all parts are in stock in order to replace the breakdown and provide the highest quality repairs. Often in all centers the price for phone repair is acceptable. over, the advantage of the services of service centers is the provision of a guarantee for the entire phone.

A fairly common reason a phone won’t charge is a breakdown of certain electronic components in the phone. In the event of such a breakdown, in any service center, a person should be explained what is the reason for this malfunction and what to do to prevent this from happening again. It is also worthwhile to understand that when they say that the phone is not charging, they also mean a quick discharge of the phone’s battery.

A fairly common and common reason is the breakdown of a battery due to long-term use. In such cases, you can simply replace the battery with a new one and it will last for a long period.

Very often, the phone turns off due to the discharge of the battery when a sound or vibration signal is given. This is justified by the fact that the phone once fell, and such a breakdown happened.

Not so often, but the phone is discharged due to internal problems, namely, some kind of virus. This reason only happens on smartphones. To prevent such a problem, you must remember that antivirus can be applied not only on computers, but also on mobile devices.

There are also malfunctions inside the phone, after which the phone itself cannot recognize the charger. In this case, it is unrealistic to recognize the problem and even more so to eliminate it. Here you just need advice and help from specialists.

The minimal problem is that the screen crashes. For example, after flashing the phone, the screen may not display the fact that charging is in progress, and the battery itself safely receives the necessary charge.

What to do if the tablet does not turn on. 2 possible problems and 3 ways to solve them

Are you familiar with the situation when, when you turn on the tablet, it simply refuses to work, still remaining Malevich’s black square? The sensations of the user in the first seconds after that. a panic fear of the possibility of a serious breakdown. But you should not despair, because most of the problems of tablet devices are easily solvable, you just need to understand the nuances of the device. So why the tablet may not turn on and how to fix the situation? The article offers detailed instructions for a home repairman.

Software errors

When the visual diagnostics of the tablet did not reveal chips, cracks, blurring on the screen, other defects and the probability of hardware failures has completely “disappeared”. we can assume that the cause of the breakdown lies in the software component.

In this case, the tablet may not turn on due to:

  • Defects the device with malicious viruses or codes.
  • Malfunctions of downloaded software.
  • Damage to the operating system or individual applications.
  • Incorrect operation of the basic settings of the gadget.

It is not easy to determine which item from this list has brought chaos to the tablet program, but you can try to reanimate it with a few simple steps.

The tablet turns on but does not boot

If the touch device gives “signs of life”, but it didn’t go beyond the logo on the screen, the reasons may be very different. The table below shows the most common ones:

Tip: To avoid data loss in case of possible tablet malfunctions, it will not be superfluous to regularly back up the most useful information. You can transfer files to the cloud or any other selected device.

Failed settings

To reset all settings of a tablet (for example, such as Huawei MediaPad T3 10) to factory settings, you need to activate the Recovery program. It starts with a certain combination of buttons, but which ones, each manufacturer decides at its discretion.

Most popular ciphers:

  • turning on the volume (add);
  • reduce the sound side power button;
  • Power Home reduce sound;
  • sound start home.

One of these configurations will work 100% and enable the required software. After the tool runs, information similar to the one in the picture below will appear on the screen. Using the sound adjustment button, the search is directed to the line “wipe data / factory reset”. To press it, Power is used.

Next, an inscription will light up, which will warn that due to such a “hard” reboot, all downloaded data, personal information, contacts, etc. will be deleted. You can save some of the information by removing the SIM card and flash drive first.

Now click Yes and wait for the procedure to complete. After a factory reset, the tablet will turn on by itself (tested on Lenovo TAB 2 A10-70L model).

Using Safe Mode

This technique will be effective if it was possible to start the tablet, but its work leaves much to be desired: constant lags, system freezes, and more. To eliminate all interference with the normal operation of the device, use the safe mode.

You can enter it by opening the settings menu of the tablet PC. the “Power off” button. hold it. It will ask if the user wants to go to Safe Mode. It must be confirmed that yes. The next field will open, in which you can delete all unnecessary files, installed programs and applications that cause incorrect operation of the device. And to update the system, you just need to restart the device.

Hardware failure

The problem lies in the equipment itself, that is, there was a breakdown of some element or the contacts came off. The most common causes of hardware failures are:
“Ripped” micro usb slot;

  • connecting incompatible or non-working devices to the tablet (the same charge);
  • any damage to board elements;
  • “Fuse” or “hung” the power button itself;
  • the battery life has come to an end;
  • the loop of the screen inside the tablet has disappeared.

The first thing to do is find a 100% working charge, connect it to a tablet (for example, to Lenovo TAB 3 850M) and leave it there for 2-3 hours. After such manipulations, even those gadgets whose battery was very badly discharged and the power controller has already disconnected it from the charge circuit often “come to life”. You can check if the battery is charging by touching the power supply: it must be warm or hot.

If a miracle did not happen, and other ideas on how to start the tablet, if it does not turn on, did not arise in my head, the only way out is to contact the service center. If your tablet is still under warranty, you can get a free repair. The exceptions are cases where there is mechanical damage or contact with water.

How can you fix a software glitch?

If a tablet from Samsung, Lenovo or another brand does not turn on, but the user knows for sure that the device did not fall or suffered from any other kind of damage, it is worth performing 3 procedures.


When working with a computer or laptop, it is the restart of the system that helps the technique to get out of the “stupor”. The same technique works for the tablet as well. To reboot it, you need to hold the power button for 10-15 seconds, then try to start the tablet again.

You might be wondering: How does a tablet differ from a laptop

Has nothing changed? Then the second option:

  • find a small button or hole with the inscription Reset on the case;
  • take a thin object (pin or paper clip), and gently press the button;
  • withstand up to 15 seconds.

Try to turn on the device. Perhaps it is after these actions that the tablet PC will start.

Important! The Reset button is not available on all tablet models. Often only state employees are equipped with such an element.

The new tablet does not turn on, but there are a minimum of options, what to do? The same reboot will come to the rescue. The new device does not have a large amount of accumulated information, and therefore the whole process will take a couple of minutes.

The tablet does not turn on: possible problems

All mini-laptop malfunctions boil down to two problems: a hardware failure and a software problem. In order to be able to independently, if not “revive” a tablet (for example, an ASUS tablet that does not turn on), then at least understand the cause of the breakdown and what to do, it is worth understanding each of the factors.

So, what to do if the tablet does not turn on, and how to identify the causes of the breakdown:

  • inspect the device for traces of impact or fall;
  • check if the device is charging;
  • try rebooting while holding the start button.

If the actions taken did not have an effect, do a full reset of the settings. When even this did not work, there is only one way out. delivery for repair.

Adapter defective or missing contact

The most common reason why a phone won’t boot or run out of power quickly is a malfunctioning charger. To verify this, you need to connect the gadget to another power supply. If it started charging, then you found the reason and the problem was in the charger. You can do the opposite, connect a known working phone to a suspicious power supply. Thus, you are guaranteed to be sure of its malfunction.

If the smartphone does not charge from a working power supply, check the connector of the contacts. A clot of dust or pet hair can get into it. Gently use a wooden or plastic toothpick to clean the socket on the phone and try again.

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

Another possibility to “revive” the battery or make sure it is working properly is to use a universal charger. In common parlance, it is called “frog” and is capable of charging any removable battery from a household electrical network.

SD card

One of the reasons an Android phone won’t turn on is to use a larger SD card than the manufacturer claims. The craving for experimentation is in the blood of users. If the specification says that only 32 GB can be used, they 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 the declared 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 bring the smartphone to a working state.

System errors and failed updates

System errors, or a resource-intensive application that is not completely unloaded from RAM, can lead to the fact that the battery begins to discharge rapidly, as a result of which the phone turns off and does not start again. A malicious program can behave in a similar way. The virus, if its task is not to extortion, runs 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 power faster than usual while in idle state, you should check it for infection and force a restart. Further actions depend on the results of the anti-virus scan.

If the smartphone is clean and charged normally, there is no cause for concern. Otherwise, if the device does not start, or the phone runs out of power again quickly, a full reset and reconfiguration will be required.

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

In case of a failure when flashing to a new version of the OS, the situation is a little more complicated. When the phone starts up, but the download does not go beyond the splash screen, the situation can be saved by the recovery mode. What to do and how to enable Recovery Mode for a specific phone is best found on the manufacturer’s website or in the documentation for the device. When this is not possible, try generic methods. The vast majority of smartphones based on Android support it by pressing the power and volume keys. It will be an Up or Down button, depending on the manufacturer of the device. You can try both options sequentially.

What to do if your phone won’t turn on and won’t respond to charging

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

There are not so many answers to the question why the phone does not turn on, what may be the reason for its rapid discharge and what to do in such a situation. Let’s consider the most common options and solutions.

Hidden defects

Some users believe that physical damage is when the phone fell on a hard surface and shattered into smithereens. Until that moment, he also fell twice, but only “slightly” scratched and wrinkled. Meanwhile, it is impossible to exclude the appearance of hidden defects from impact on the body of the gadget. Damage to the internal contacts will result in the Android phone not turning on or charging, and sometimes working and suddenly shutting down. So if your phone fell, it is impossible to fix the malfunction of the motherboard on your own and you will have to contact a specialist for a complete diagnosis and a possible replacement of components.

If the phone does not turn on even after you have gone over all the probable reasons, you should contact the service center. Without showing excessive initiative in trying to revive it, you will save yourself time and nerves for specialists.
