Screen Does Not Work Samsung

Samsung

Read more about the reasons why the screen does not work on the Samsung phone

We have already said above that the exact cause can be identified only with the help of diagnostics on the professional equipment of the service center. But, consider the main signs.

It is worth mentioning that under this breakdown, many smartphone owners often mean a non-working touchscreen, i.E. Touch screen. Describing a breakdown as a non-working display, it means that the screen does not respond to touches. We are considering cases when the display does not work, i.E. No picture.

The reasons

  • Physical damage. This category of causes includes not only shocks and falls, but also the ingress of liquids. There is not always visible damage on the screen surface. A microcrack in the board or one of the connecting components is enough for the screen to stop working. The influence of liquids was discussed earlier.
  • The display stopped working after updating the firmware. Here are the cases when the phone turns into a brick and does not fully respond, or there is an indication of switching on (diodes are on or there is a vibration response), but the screen still does not turn on. Probably the firmware is not suitable, or there was a failure during the update and the installation went wrong. In this situation, you will have to reflash the smartphone again.
  • The screen stops working while using the smartphone. Those. You are using your Samsung and at some point the screen goes blank. There is a high probability of failure of the proximity sensor, which is responsible for locking the screen during a call when you bring the phone to your ear.

We have listed all the reasons and cases of display failure in phones from Samsung and any other manufacturer. Most often, of course, the cause is physical injury.

Our advice: contact the service center. Trying to figure out the problem yourself, you can only harm and make the final repair more expensive.

Displaying the Android screen on a computer

This method is more complicated and will work if you had previously enabled USB Debugging on your phone.

You will need the ADB Run program. You can download its latest version and read the instructions THIS LINK

The bottom line: the phone screen is displayed on the monitor screen of your computer under Windows OS and you use the mouse to do what you need on the phone. In this case, save numbers or data.

Touchscreen not working on Android

In this article I will tell you what to do if the sensor (touchscreen) does not work on your Android phone and how you can pull / copy data or contacts from it.

This article is suitable for all brands that produce phones on Android 10/9/8/7: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

Attention! You can ask your question to a specialist at the end of the article.

  1. What to do if the sensor does not work on your Android phone / tablet
  2. How to transfer contacts or copy data with a broken sensor to Android
  3. We use the manufacturer’s standard programs
  4. Using a USB wired mouse as a manipulator
  5. Displaying the Android screen on a computer
  6. Other ways

Using a USB wired mouse as a manipulator

If your phone model supports OTG technology (you can find out in the specifications for the phone or google), then through the adapter you can connect a USB mouse and how to manipulate the transfer or synchronization of data with the cloud on a computer.

The adapter looks like this:

By the way! If you previously connected a mini-keyboard with a touchpad or a joystick to a Bluetooth phone (they were paired and saved in the phone’s memory), you can use them, provided that Bluetooth is enabled in the phone at the moment.

We use the manufacturer’s standard programs

The bottom line: each manufacturer has its own program for backing up phone data via a USB cable. Those. Put the program on the computer, connected the phone to the computer via USB and in the program choose what you want to copy or transfer.

Here’s a sample program for some popular brands. If you have another manufacturer, look for the link on its website:

  • Samsung Kies
  • HTC HTC Sync
  • Sony PC Comanion
  • Huawei HiSuite

What to do if the sensor does not work on your Android phone / tablet

In 99.9% of cases, physical damage to the screen is the cause. Even if no visible damage is visible (chips, cracks), the internal loop or one of the modules could be damaged. If moisture gets into the case, corrosion or module failure could occur.

Exit to contact the service center. It is unlikely that you yourself will be able to properly glue and then glue a new display module (now more and more often the screen is integrated with the sensor). This will require a special tool, experience and the new display module itself. I recommend entrusting this to the pros who will give a guarantee.

Our task is to understand how to extract the necessary information, since in the service it is unlikely that someone will do this and you need to keep your data confidential. At the same time, you do not have a data backup and you do not use cloud sync.

How to transfer contacts or copy data with a broken sensor to Android

There are several options. We select the right one for ourselves.

Apowersoft Phone Manager

A multifunctional program that allows you to manage your phone files, even if the phone’s sensor is faulty. True, you won’t be able to get access on a device with a completely inoperative screen: it must be possible to install the client on the phone.

To evaluate the functionality of the application, it must be installed on a Windows computer. The same must be done on a mobile device. Android owners can find the app on Google Play and download it by scanning the QR code. Next, you need to do the following:

  1. Connect the gadget to the computer using a USB cable.
  2. Launch the application and access the smartphone screen.
  3. Transfer the necessary data from the phone to the PC via the Export button, specifying the appropriate directory.

It is noteworthy that the screen diagonal in the Apowersoft Phone Manager application can be changed by decreasing or, conversely, stretching it to the maximum.

Displaying the Android screen through the browser

One of the easiest and fastest ways to establish control of a smartphone through a computer is to use the Google Chrome browser. In this case, third-party applications are not needed. Displaying an image on a PC without programs looks like this step by step:

  1. Opening the Chrome browser
  2. Installing the Vysor extension.
  3. We connect the smartphone to the computer via USB and run the installed utility.
  4. Click Find devices and select the desired device.
  5. Confirm USB debugging
  6. We get access to the phone via PC.

Broadcasting a screen from Android to a computer is possible not only through a browser, but also using special applications. About them further.

Phone display not working: types of breakdown

Many smartphone makers have removed the hardware interface to save on size, weight and cost. The result is a device that you can only interact with via a touchscreen.

Several scenarios for a non-working display can be described:

  • Small crack in the screen
  • Cracked screen, part of the screen not showing
  • Cracked screen, touchscreen not working
  • Crack with broken touchscreen and display problems
  • The screen is not cracked, but the sensor does not work

Each type of breakdown will affect the way you use your phone. However, none of these should render the device unusable.

A practical solution for a smartphone with broken display repair. However, some problems can prevent this: for example, lack of warranty or unavailability (high cost) of spare parts.

If you cannot fix your phone professionally, you can replace your damaged phone display.

In the following sections, you will learn how to access your phone despite a broken touchscreen display. Having gained access, you can recover data from the device.

Androidscreencast

Androidscreencast is a free utility for viewing phone content and remotely controlling the device via PC. Can be used on Android 4.1.1 smartphones and tablets with faulty screen.

Phone remote control: best apps

The first step in managing a phone that has a broken screen is preparing the smartphone. To do this, you must enable USB debugging. This can be done through the settings of the device, if, of course, the touchscreen and some part of the screen are functioning.

  1. Go to Settings Phone Information.
  2. Click on the build or firmware version (7 times) until a notification appears on the screen about entering developer mode.
  3. In the Developer options section, activate the USB Debugging item.
  4. Reboot your phone.

As a result, access to the phone screen via USB will be provided. This will allow you to recover data or obtain the necessary information through special programs.

Accessing the phone with keyboard and mouse

If the display turns on and you can see at least part of the screen (but you cannot use it), try the option with connecting a keyboard and / or mouse.

There are different connection options depending on the platform and Android version of your smartphone.

To access the screen you need:

  • Phone with USB OTG support
  • USB mouse / keyboard (or wireless adapter)
  • USB OTG adapter
  1. Turn on your phone
  2. Connect the USB OTG adapter to the phone jack (usually USB-C or Micro-USB)
  3. Connect a keyboard or USB hub with keyboard and mouse attached to the adapter.
  4. Control your smartphone with a mouse and keyboard.

Screen damage

Service centers often receive questions about what to do if the screen does not work after the phone is dropped. In fact, if the reason really lies in the fall, then you will definitely not be able to solve this problem on your own. The phone can only be repaired by contacting the service center.

It should be noted that when the device falls, several damage options are possible:

  • Damage to the display. Such situations can be solved only in one way by replacing the display, but it is almost impossible to do it yourself. It is best to take the phone, the screen of which is off, to a Samsung service center, where specialists will replace it with the original one.
  • Damage to the screen control chip. If the screen of a device from Samsung does not turn on, this does not mean that the display is to blame for everything. It is not uncommon for people to replace the screen, but the problem is still not solved. Replacing the microcircuit is quite cheap, which allows you to solve the problem as quickly and efficiently as possible. It is not recommended to do this on your own, as you need specialized equipment for soldering the boards.
  • Damage to the connection of the connector to the printed circuit board. This situation is as simple as possible. To solve it, you only need to disassemble the smartphone, the screen of which has gone out, and insert the detached part in its place. 90% that this method will help your device.

It is worth mentioning that there are other rare problems as well. Which can only be identified at service centers. Contact the experts if you have a screen on your Samsung phone. Samsung smartphones do not fail as often as they say.

Discharged battery

Let’s first analyze commonplace problems that can cause the screen to stop working. Let’s start with the difficulties that can be associated with the battery. Most often, the battery simply does not receive the proper amount of energy from the charger. On Samsung, this can happen as a result of a faulty charger that stops working properly, due to the burnout of the microcircuit inside the power supply.

Such cases are not rare and happen all the time, as a result of strong voltage surges. With a significant increase in the input voltage, the board burns out. It’s good if the charger suffers, and not the device itself.

It is also worth mentioning that the battery may fail, but this rarely happens on devices from this company. This problem can be solved by simply replacing the battery with a new one. You can do it yourself, just choose the right battery.

Why Samsung Smartphone Screen Doesn’t Work Causes and Solutions

Not everyone is watching their smartphone closely. Quite often, unforeseen situations arise due to the fact that the device does not turn on or the screen does not work on Samsung. This can happen for completely different reasons, ranging from ordinary mechanical damage to a factory defect. Let’s take a look at the most common reasons why a smartphone stops functioning correctly.

Operating system errors

If the device freezes and does not turn on after that, then it is highly likely that the main problem lies in the operating system. Android OS (this is especially true for older versions) is not famous for its stability, so sudden errors can occur regardless of the brand and model of the smartphone.

In such situations, not everything is clear, because in most cases, when the screen does not turn on, and the problem arose after freezing, you just need to pull out the battery for a couple of minutes, after which, most likely, the device will start without problems. Unfortunately, it is not always possible to solve the problem in this way, because sometimes the phone does not start even after that, and some devices are equipped with a non-removable battery (use the reset button located on the smartphone body). Where to find it, read the instructions.

If all the tips that were given above could not help you, then you will have to reset the device settings to factory settings. Unfortunately, all your data will be deleted, but the good news is that the operating system will start functioning normally again. Follow the instructions below:

  1. Hold down the Volume Up and Home keys.
  2. Press the power button without releasing the pressed keys.
  3. In Recovery Mode, you can roll back to factory settings. This process is individual for each smartphone, so you should look for instructions on the Internet.

Now you have learned about what to do if the screen of a smartphone released by Samsung does not work, you can summarize. Do not disassemble the device yourself if you are not sure of the success of the actions. Entrust it to the professionals working in the service centers. Only they can correctly diagnose a breakdown and replace a failed module.

Why Touch Phone Screen Doesn’t Work?

The touchscreen display on any phone can stop working for many reasons. Here are the most common problems that make your smartphone screen unresponsive to touch:

  • Physical damage resulting in damage to the touch screen. High temperature, cold, humidity, magnetism, or static electricity can damage the touchscreen on your Android phone.
  • Malware or performance-enhancing applications that affect the phone’s system in such a way that the sensor does not respond to touch. (Antivirus is recommended to avoid this)
  • Android system crash after firmware update, incorrect reboot, insufficient RAM or internal memory.
  • Incorrect settings.

A factory reset (resetting your phone to factory settings) will restore your phone to its default settings and fix most of the above issues. If the touchscreen just stops working for no clear reason, it is probably caused by a software issue. How to fix a touchscreen with physical damage later in the article.

Phone sensor does not respond to touch first aid guide device

Very often, the touch screen on a smartphone starts working incorrectly, incorrectly, or simply does not respond to pressing. As a rule, all problems in this case can be divided into 3 groups:

  • The touchscreen has stopped working on the smartphone and is completely unresponsive to any taps.
  • The touchscreen is not working properly: when you press a you get b.
  • Delay when clicking, braking, screen distortion, color change.

Let’s try to understand the reasons for such breakdowns and try to eliminate them without resorting to specialized service. No matter what model or brand of phone you are facing, this guide will help you solve almost any problem.

The smartphone screen does not respond to any touch what to do?

If the touchscreen has no physical damage but suddenly stops responding to your touch, it could be caused by a software problem. Here are the main and most effective ways to fix the problems that have arisen:

Before delving into any other troubleshooting procedures, restart your phone or tablet to fix software errors that might prevent your device from working.

Reboot any Android touchscreen device as follows:

Press and hold the power button until the screen turns black.

After 1 minute, press the power button again to turn on the device.

In many cases, the phone will respond normally to touch after rebooting.

Remove the memory card and SIM card

Sometimes a faulty memory card or SIM card is to blame. Hence:

  • Reboot your device and check if the problem is gone.
  • Put your device into safe mode

Corrupted or extraneous apps can also cause a touchscreen issue on your phone or tablet.

In safe mode, all downloaded third-party applications will be disabled, i.E. Only standard applications will be loaded, which are necessary for the operating system to work and maintain the minimum functionality. Therefore, if the display works well in safe mode, you should uninstall some applications, especially those that were installed very recently, before the touch screen problem.

  • Turn off your Android device.
  • Then long press the power button to reboot the device.
  • When you see the phone brand logo, release the power button, press and hold the volume down button.
  • Release the volume down button when the device boots up with the safe mode indicator in the lower left corner.

Attention! If your phone sensor is not responding to touch, lags behind, slows down or responds incorrectly, you can also try using this method.

When you see a message about restarting your device in safe mode, click OK. Safe Mode is enabled. If no problems are observed, start uninstalling third-party applications by periodically rebooting the device and checking the smartphone’s operation in normal mode.

  • Restore to factory settings

If the touchscreen is completely unresponsive, it may need to be restored to factory settings.

This procedure will erase all data on your device, including downloaded apps, photos, messages, contacts, etc. WITHOUT POSSIBILITY OF RECOVERY. Therefore, use this method as your last chance. Back up your Google account in advance.

The steps to enter recovery mode are different for many Android models. In other articles, we have already mentioned how to do this, so we will not repeat ourselves and proceed to the next method.

  • Calibrating the touch screen using the app

Type touch screen calibration in the Play Store search bar and the system will give you quite a few results.

Read the reviews carefully before downloading any of the applications, give preference to verified authors.

Physically damaged touchscreen: how to fix it?

If your phone or tablet has been hit, dropped, or otherwise damaged, the sensor will most likely stop working 90% of the time. Do not rush to run to the service center! Before replacing a new display, try these free tips first:

  • Preliminary diagnosis of damage

What to do if the touchscreen does not work after a fall? A diagnostic test won’t fix the problem, of course, but it does help determine which areas of the screen are really not responding. To access the diagnostic tool, you need to enter a specific USSD code in the dialing line of the phone number.

All codes differ for Android devices of different manufacturers, models, OS versions. Here are some tested codes that are commonly used (symbol. DO NOT write after the # symbol):

# 7353 # most Android smartphones, especially Samsung;

# # 3424 # # for HTC;

# # 7378423 # # Sony Xperia series smartphones;

# 0 # Motorola and subsidiaries.

For example, here’s how the test is performed on a Samsung Galaxy S4, Android 4.0:

  • Open the phone dial.
  • Enter # 7353 # to enter the diagnostic tool menu.
  • Select TSP Dot Mode or TSP Grid Mode which are used for touch screen testing.

TSP Dot Mode will show small dots when you tap on the screen, while TSP Grid Mode allows you to test every area of ​​the screen in a grid overlay. By using both of these modes, you can determine which part of the display is most affected.

  • Broken cable

If the device is dropped, the digitizer cable may be loose (detached) and the touchscreen may not respond. This can be fixed fairly easily by tapping lightly on each corner of the touchscreen several times. In 50% of cases, this method helps.

What to do if the sensor does not work on the Samsung a50 or does not respond well

First forced restart. This is important because it will refresh your phone’s memory. It is always possible that the problem is caused by a system crash or that some services have stopped working causing the touchscreen to stop responding.

To do this, press and hold the Volume Up and Power keys at the same time for 10 seconds or longer.

Your phone will start normally, but if the problem is really minor, then that should be enough and the touchscreen may work again.

Second security mode. You must enable safe mode if the problem persists after a forced restart how to do it is described here.

This will temporarily disable all third-party applications and will immediately inform you if the problem is caused by a third-party application or not.

If the touchscreen works fine in this mode, it means that a third-party application or service is calling it.

In this case, you need to move on to the next solution to fix the problem, but if the problem persists in this mode, skip uninstalling some applications and proceed to deleting the system cache.

Uninstall third party apps. The uninstallation of third party apps is triggered by the next step to be followed if your touchscreen is in Safe Mode.

It can be tricky, especially if you don’t know which app is causing the problem, but once you point it out, it will definitely fix the problem.

Third, clear the cache partition. To do this, you can boot the phone in recovery mode, but there is a simpler way, instructions here.

Caches are temporary files created by the system itself to keep your phone running smoothly and flawlessly, but they are prone to damage and when this happens, this is just one of the problems you may encounter.

Fourth factory reset. After following the previous procedures, the touchscreen is still unresponsive, you have no choice but to reset your phone to rule out the possibility that this is only a temporary software issue.

Please back up important files and data before resetting as they will be deleted, so please back up your data. Who does not know how to reset can find out here.

Fifth, take the phone to a service center. If all else fails, there may be a hardware problem, specifically the digitizer that is part of the display module.

It may already be damaged, or it may be a minor flex cable issue. However, this is a hardware problem and you need the help of an authorized technician to open your phone without losing your warranty.

I hope I was able to help you fix this with your device. Thanks a lot for reading! Success.

What to do sensor stopped working on samsung galaxy a50

Although Samsung Galaxy a50 phones have appeared quite recently (with the release of android 9), there have already been isolated cases that the sensor stopped working or if it works, then it is bad.

Let’s hope that if your sensor does not work, then the reason is not in the hardware, which can result from an impact when dropped, water ingress, exceeding the permissible temperatures, damage to the screen controller or a factory defect.

In such cases, you may need to replace the sensor on your samsung galaxy a 50, sensor controller, flex cable, connector, or cleaning from traces of corrosion.

Yes, sometimes these hardware components can stop working for some reason, but somehow I will share with you troubleshooting procedures that have proven to be effective in fixing problems when the sensor is not working.
