How to find apps that take up a lot of space and reduce their size

We found out that memory itself cannot be lost, there are always some applications behind it. The question is. Which ones, because each one has different ones installed. Therefore, you need to find out which applications take up the most space on your device: open MenuSettingsApplications or Application ManagerApplication Manager (if there is such an item) → the list of applications will open. Under each application, you will see how much memory it takes.

Test the applications one by one and identify the ones that are taking up the most memory. You need to work with them further.

If you have a lot of space occupied by instant messengers (WhatsApp, Telegram, Viber.), Then most likely the memory is filled with pictures, stickers and voice messages. This happens unnoticed because these files are downloaded automatically. We recommend that you disable automatic download of these files. Below are the settings for the most popular messengers. For other messengers, please try to find similar settings yourself.

Whatsapp: in the chat list three dots top right → SettingsData and storage → in the Media Startup section, items Mobile network, Wi-Fi, In roaming → uncheck all boxes. Also in paragraph Vault you can see how much space the files are taking for each contact and delete them by selecting the contact and clicking Free space.

Telegram: in the chat list three dashes top left → SettingsData and memory → in the Media Startup section, items Via mobile network, Via Wi-Fi networks, In roaming → slide the switches to the left.

Viber: in the chat list three dashes bottom right → SettingsData and multimedia → items GSM autoload and Autoload over Wi-Fi → uncheck all boxes.

If other applications are taking up a lot of memory, then most likely the memory is being filled with cache. You can try to remove it for each application.

Important information!

Deleting a cache is not a one-time step. Have to repeat it every time the memory runs out.

Deleting the cache should not, but may affect the information stored in the application.

Removing the cache should not, but may affect the further performance of the application.

It is impossible to predict exactly how an application will behave after deleting the cache, because the programmer who wrote it might have associated important functionality with it. Therefore, if the application contains some important information, do not delete the cache.

To remove the cache: open MenuSettingsApplications or Application ManagerApplication Manager (if there is such an item) → select the application for which you want to delete the cache → Memory (if there is such an item) → Clear cache.

Why is there less free memory than stated in the specifications

One of the frequent questions is why there is less free memory than stated in the specifications of the device, for example, a smartphone with 8 GB of memory, and about 700 MB free.

The device specifications indicate the physical size of the memory module that is installed in it. For a smartphone or tablet to work, you need an operating system and service applications that are installed on this module. The amount they occupy depends on the device: for example, on the Galaxy J1. 6.5 GB, and on the Galaxy S10. 20 GB.

It turns out that the operating system takes up part of the free space from the total volume. That is why there is less free memory than indicated in the specifications.

As you can see from the recommendations above, pictures,, music can be easily transferred to a memory card, but there are very few applications that support this function.

Therefore, if you plan to download a large number of applications, especially games, buy a device with a large memory capacity. At least 16 GB, and in order to comfortably use the device. From 64 GB.

How to see how much memory is free

On most devices, the amount of memory can be viewed in the application My files (often found in the menu, in the folder Samsung). The first number shows how much is busy, the second shows how much memory is in total.

If on your device in the application My files such information is not displayed, you can find it in MenuSettingsMemory.

What to do if free memory runs out

Any application consists of three parts: application, data, cache. A detailed article that describes all three parts and what they are for is below the link.

In short, data and cache are the changing parts of an application that are needed to make it work. They can grow the original application size from a few megabytes to several gigabytes.

That is why it may seem that memory is wasting: during operation, installed applications increase their volume. Applications that work with the Internet are growing the most: YouTube, Facebook, Twitter, VKontakte, Instagramm, WhatsApp, Browsers and other similar applications.

For example, YouTube takes 30 MB immediately after installation:

And after watching severals already 259 MB:

Increasing the memory footprint is normal for applications to run. Therefore, if the memory on the device is constantly running out, the options are only as follows:

1. Buy a device with a large amount of memory and stop suffering from lack of memory;
2. Reduce the number of applications and keep cleaning the memory manually.

What happens when memory is full

When the memory is full, the device starts to slow down and freezes. A corresponding notification also appears on the screen.

To prevent this from happening, keep free at least 500 MB of main memory. If the memory is still full, use the recommendations from this article.

How to clear memory: delete photos, music, and other files or transfer them to a memory card

The application is used to manage files on the device My files. It is analogous to File Explorer on a Windows computer.

Find the app My files in the device menu and open it. It is often found in the folder Samsung.

From the start screen select Device memory.

The folders and files are displayed as they are stored in the device memory. Now you need to find large folders. To do this, select any folder (two options, the method depends on the device):

1. Or tap on the folder and hold it for a few seconds. A square or circle will appear next to the folder, and a check mark will appear in it;
2. Or, if there is a square or circle next to the folder, click on it. A check mark will appear in it.

Click on Options in the upper right corner (may look like three dots) and select Properties or Intelligence.

Also, this item may be at the bottom of the screen (no need to press Options).

In step The size the volume that the folder occupies will be displayed. If the folder takes up a lot (more than 300 MB), it is better to transfer it to a memory card.

Usually the largest folders are: DCIM. Photos from the camera, Download. Downloaded files from the Internet, WhatsApp or the name of other instant messengers. Files from chats in instant messengers, Music. Music.

To move, highlight the folder again, press Options and select Move. To delete, select Delete. You can move not only folders, but also individual files that are stored in these folders.

Also, these items can be at the bottom of the screen (you do not need to press Options).

Select item Memory card, and then Done or Move here. Folder moved.

Smartphone display elements

Before studying the direct instructions, you should figure out what modern displays used in most smartphones consist of. Their components include:

    Matrix. A panel of liquid crystal or LED type that contains an array of pixels that form the final image. On the back there is a stainless steel case, and the front part is covered with thin glass. The design includes a ribbon cable that connects the screen to the board of the mobile device.

A touchscreen is a panel that is placed on top of the matrix and registers the user’s touches. The software combines the received information with the arrangement of elements on the screen and performs the appropriate action. When falling, it often takes a hit on itself, as a result of which it cracks. Replacing this element is cheaper than matrices.

These components can be attached to each other in two ways:

    Through the air gap. This is a simpler design used previously, which means easy glass replacement without the use of special tools.

Without an air gap. The so-called OGS-display, which is a single whole, combining a matrix and a touchscreen. The replacement can be carried out independently, but it takes more time and requires the use of special devices.

How to change the main glass of a smartphone?

Touch screens have seriously expanded the functionality of mobile devices, but since the beginning of their use, technology had to be treated more carefully. Almost any fall from a height exceeding 1 m can damage the main glass of the phone or even the matrix. Tempered glass is used to protect the screen, and the phone itself is often worn in a case.

In the current article, we will figure out whether it is possible to replace the glass on a smartphone and how to do it depending on the design of the display. We will also consider the process of removing and gluing the protective glass, which will save you from the occurrence of more serious problems.

Replacing the protective glass on a smartphone with your own hands. How to replace the glass on your smartphone yourself

It follows from the above that the replacement is carried out by two different methods, depending on the type of connection of the matrix with the touchscreen.

Replacement on screen with air gap

Now let’s figure out how to replace the glass ourselves on a smartphone, the screen of which has an air gap. In this case, the procedure is not so complicated and can be done quite simply at home. In this case, you will be able to save a decent amount. Before starting work, make sure you have the following tools:

  • Small Phillips screwdrivers;
  • Plastic scraper (how to pry the elements);
  • A suction cup made of silicone and equipped with a ring;
  • Hair dryer for heating;
  • Glue B-7000 or similar;
  • Medical rubber gloves.
  • Glass replacement is carried out in the following stages:

    • Phone disassemble.
    • The screen is detached.
  • It is warmed up with a hairdryer to a temperature of 80 degrees. It is important not to exceed the specified temperature and not stay in one place for a long time, so as not to damage the component.
  • After warming up, the display is attached to the suction cup and the touchscreen is separated.
  • The body is cleaned from glue residues.
  • The touch screen is being prepared: the film is removed, double-sided tape is glued around the perimeter or glue is spread.
  • The touchscreen is pressed against the matrix, the excess glue is removed with a napkin.
  • After the glue dries, the components of the phone are assembled and checked for operability.
  • These are the two main methods of replacing the touchscreen on a smartphone on your own. And to avoid further damage, a protective glass is glued to the touch panel. Let’s analyze this procedure in more detail.

    How to remove protective glass from a smartphone

    First of all, you need to remove the old protective glass. Replacement is often done after it has been broken, so the procedure will be described from this perspective:

    • There is the most intact corner on the glass, where there are no signs of damage (usually the farthest from the impact site).
    • A sucker clings to this corner.
  • A plastic pick or similar thin object is carefully inserted between the screen and the protective glass. Gradually, the pick is pushed further, and the suction cup is pulled towards itself. Often, after peeling off one edge, the glass is easily separated by hand.
  • When performing the procedure, the most important thing is not to damage the main glass of the phone.

    3. Explore the characteristics of the desired smartphone or tablet

    If you study the technical characteristics of the desired smartphone or tablet in advance, this will help distinguish the original from a fake. The fact is that copies have significantly better specifications, so it won’t be difficult to see the difference.

    Ask the seller to test the device against popular benchmarks such as Antutu, Geekbench, and GFXBench, and then send you screenshots. Most likely, he will refuse to do this, which is a good confirmation that the device is not original. We also recommend installing the AIDA64 program on the phone, which displays a complete list of characteristics on the screen.

    Copies, for example, use other screens, processors, memory, flash drives, and cameras.

    2. Check by IMEI

    Checking by IMEI number is not a very reliable way to determine if the device is original, but in many cases it really helps. The determination procedure is also not very complicated, it consists of only two steps:

    First you need to find out the IMEI number of the phone. To do this, enter the service code # 06 # in the dialer and in a moment you will see it on the screen. It also has on the box from the device and we recommend checking them at the same time (the numbers must match).

    Now go to the Samsung website and enter the IMEI. It’s worth noting that you won’t check the device here if it’s older than the Samsung Galaxy S7. For example, I entered my Galaxy Note 4 number and the system reported an error. In this case, use the services of another service. IMEI.Info. Enter the same number and press the “Check” button to check. You should see device information if it is original.

    Keep in mind that highly advanced scammers can steal the real IMEI from a genuine Samsung gadget and replace it with a Chinese copy. However, this happens very rarely and the third method will help you make sure whether the Galaxy is a fake or an original device.

    1. Checking with the service code

    This is the easiest and fastest way to test any Galaxy smartphone for originality. Each device of the company has a proprietary menu that is launched by a secret code.

    1. Open the dialer app
    2. Enter code # 7353 #
    3. Such a menu should appear on the screen, where there are various options for testing phone components.
  • If you have it, then the device is original.

    Now you know all the popular ways to check a Samsung smartphone for originality. If you still have any questions. Feel free to write them below.

    What is “Safe Mode” in Samsung?

    Safe mode is an operating system mode in which all third-party applications installed on the phone (computer) are disabled. In fact, in it the device is its own factory sample, with the operating system installed on it, and nothing more.

    Samsung‘s independent transition to security mode means that something has gone wrong in the system. Usually the reasons for this are an error in the operation of an application, various viral and adware software, hardware failures in the phone, and other factors.

    Safe Mode. A handy tool for diagnosing problems on the Android OS. If you manually activated Safe Mode, then you probably want to see which of the applications is causing your system to crash or freeze, and the rapid discharge of its battery. However, if you entered safe mode by accident, and do not know how to get out and remove from it, then this material is for you. Let’s take a look at what Samsung smartphone owners should do in such a situation.

    Removing battery and SIM card from Samsung

    If your phone boots into Safe Mode and you can’t turn it off, a method to remove the battery from your phone can help. In this case, you need to remove the back cover of the device and remove the battery (of course, if it is removable).

    Also remove the SIM card.

    Wait a couple of seconds, then put the sim card back in and reconnect the battery. All that remains is to put the cover back in place and turn on the phone.

    Testing the system for harmful applications

    Although you cannot use third-party applications in Safe Mode, their data and cache are not blocked. As a consequence, there is a possibility that the downloaded application puts your phone in Safe Mode. Thus, we need to get rid of the malicious influence of such an application on our system.

    Exist three ways solutions to this problem: clear cache, clear app data and uninstall app.

    Let’s start by clearing your Samsung’s cache:

    1. Open your device settings;
    2. Select “Apps and notifications”;
    3. Then click on “See all apps”;
    4. Tap on the name of a malicious application in your opinion;
    5. Click on “Storage” and then tap on “Clear cache”.

    If that doesn’t work, then get started cleaning up the storage. Be careful: deleting app store deletes cache and your user data in the specified app.

    You can clean up Samsung storage as follows:

    1. Open your phone settings;
    2. Select “Apps Notifications”, then click “View All Apps”;
    3. Tap on the name of the malicious application;
    4. Click on “Storage” then click on “Clear Storage”

    If clearing your cache and app storage didn’t help turning off Safe Mode, it’s time to uninstall the app itself:

    1. Open the settings;
    2. Select “Apps Notifications”, then click “View All Apps”;
    3. Tap on the name of the problematic application on Samsung;
    4. Select “Uninstall” and then click on “OK” to confirm. This can help disable Security Mode.

    Using hardware buttons to disable safe mode

    You can also remove Safe Mode on Samsung using the functionality of your phone’s hardware buttons.

    1. Turn off your device.
    2. After turning off the device, hold down the power button;
    3. When you see the Samsung logo on the screen, release the power button;
    4. Then quickly hold down the volume down button.

    After completing the above steps, you will see a message about disabling Safe Mode.

    What you should pay attention to: What to do:
    A breakdown of one of the volume buttons may make the phone believe that you pressed and hold this button (especially when it comes to the volume up key). It can force your phone to boot into Safe Mode over and over. In this case, it is better to visit your local service center to solve the problem.

    Factory reset Samsung phone to remove Safe Mode

    You can get rid of Safe Mode on Samsung with the help of a phone reset to factory settings. This method can be considered as the most radical option, since all your files and progress in games will be lost.

    Factory reset method differs on different Samsung models.

    For example, it may consist of doing the following:

    1. Open your phone settings;
    2. Select “System” there, and then click on “Advanced”;
    3. Tap on “Reset parameters”, and then select “Erase all data”;
    4. Below, click on “Reset phone” or “Erase everything”.

    How to calibrate the screen on Android?

    There are two main ways to tidy up a damaged touch sensor. Special programs and with your own hand. We should also remind you that for HTC, Samsung, Nokia and other Android devices, the calibration procedure is almost identical. You can also see how to set up auto-rotate screen.

    What it is?

    Screen calibration is setting up the touchscreen to correctly execute commands when you touch it with your fingers or stylus. Of course, you can work with your device without such a setting, but then get ready to waste your nerves, time and other troubles.

    This procedure is required in most cases after the phone has been dropped, especially in water. Replacing the screen, the water stain under it, even the smallest damage may require urgent adjustment. Checking if you need calibration is as easy as shelling pears. First, remove the protective film to make the sensor work as clear as possible, then just enter any number or letter. If you chose, say “B”, and “A” appeared on the screen, then be sure. You need to set up the touchscreen.

    Calibration of the touchscreen on Android phones and tablets

    Many owners of Android devices with a touch screen often face a problem when the screen “does not listen” to them. That is, when you touch the touchscreen with your finger or stylus at one point, the phone perceives it as touching completely at another point. Or, the sensor will follow orders at all with only 3-4 attempts. And most likely the cause of these problems is the incorrect operation of the screen, and in order to fix it, you need to calibrate the touchscreen of the Android device.

    Calibrate the Android touchscreen. Android sensor calibration: programs, settings

    Setting using special programs

    In the free, and most importantly. In the free, access, you can find a lot of software for screen calibration. They are easy to install, easy to operate and, what is important, they give results. For example Clinometer, TOPON, Bubble. Just take a look at Google Play. But? Even if you don’t have access to Google Play, you can adjust the display without it using the second method.

    Step 2. Cleaning the touchpad

    The sensor may not respond to touch when the panel is dirty or when touched with wet fingers. Make sure your fingers are dry and the sensor surface is clean.

    How To Check The Touchscreen On Samsung

    You can use a damp cloth to clean the touchpad, then wipe the surface dry.

    Step 4. Reinstalling drivers

    The sensor may not work correctly or not work at all due to problems with the device driver. This situation can occur after reinstalling the operating system.

    To solve this problem, you need to install the correct driver from the CD that comes with the laptop, or by downloading from the manufacturer’s website.

    Step 1. Turn on / off the touchpad on the keyboard

    90% of the problems of a non-working touchpad are solved by its banal inclusion.

    To do this, you can use a key combination consisting of the mandatory Fn key and the system key, which may differ depending on the manufacturer and model.

    Here are the key combinations for the most common laptop manufacturers.

    Ace r: Fn F 7

    A sus: Fn F 9

    D e ll: Fn F 5

    Fuj і tsu: Fn F 4

    G і g а byt е: Fn F 1

    L e n about v about: Fn F 6

    Hewlett-Packard (HP)

    HP, as well as some other laptop manufacturers, prefer to move away from the standard layout of the Fn Fx keys and move the touchpad power button directly to the touch panel, it is located in the upper left corner and has a light indication for ease of operation.

    To enable / disable the touch panel, double tap on the button, which is also touch.

    Touchpad does not work on a laptop: how to animate the cursor?

    The touchpad does not work on a laptop, what to do and where to run?

    First of all, you need to figure out what a touchpad is, and what could be the problem.

    Touchpad (from the English touchpad. Touch pad). A device for controlling the cursor in laptops, netbooks, ultrabooks.

    The device was invented in 1988 by George Gerfeide, but gained popularity only 6 years later, after licensing and installation on Apple PowerBook laptops.

    • Step 1. Turn on / off the touchpad on the keyboard
    • Step 2. Cleaning the touchpad
    • Step 3. Enabling / disabling the touchpad in BIOS
    • Step 4. Reinstalling drivers
    • Step 5. Hardware failure of the touch panel

    Possible problems with the cursor control panel and options for solving them will be discussed below.

    Most laptop owners prefer to use a mouse for comfortable work rather than a built-in touchpad. A touchpad.

    The need to disable the touchpad may arise if you have a stationary computer mouse, as well as if you plan to type large amounts of text.

    The fact is that when typing, there are often cases when the cuff of a shirt, for hours, you can accidentally touch the touchpad, as a result of which the cursor moves over the text.

    In some laptop models, the process of disabling the touchpad is automated, but you have to enable it manually.

    Most laptop users, probably at least once faced with a situation when a computer mouse is not at hand and the only way out is to use the touchpad, which also refuses to work.

    Below we provide a list of the most common touchpad problems and how to solve them.

    Step 3. Enabling / disabling the touchpad in BIOS

    A less common phenomenon than the previous two, but also sometimes occurring. Disabling the touchpad in the BIOS.

    To fix the problem, go to the laptop BIOS. You can go to BIOS settings at the boot stage by pressing a certain key on the keyboard.

    The name of the key depends on the BIOS manufacturer. Usually these are the Del, Esc, F1, F2, F10 keys, etc.

    The moment when you should press the key can be determined by the appearance of the inscription with the name of the key to go to the BIOS. If you start pressing earlier or later, you will not be able to enter the BIOS.

    Next, you should find the menu item responsible for enabling / disabling the built-in pointing devices “Internal Pointing Device” (in our case, it is in the Advanced section), and see its state.

    Touch panel operation is possible if the value is set to “Enabled”, i.E. “Enabled”, if the set value is “Disabled”. The touchpad is disabled.

    Step 5. Hardware failure of the touch panel

    If none of the above tips helped, most likely we are dealing with a hardware rather than a software problem with the touchpad.

    Such problems include poor-quality connection of the cable to the motherboard or mechanical damage to the panel.

    If you are confident in your abilities, you can disassemble the laptop and check the quality of the loop connection. Sometimes, in order for the touchpad to work, it is enough to fix the connection connector.

    If you have no experience in assembling laptops or are not sure that you can do everything correctly, we recommend that you contact a qualified specialist or a service center.
