Is it possible to change the touchscreen without disassembling the phone? How to distinguish what is broken - a touchscreen (glass, touch glass) or a display

Hi all! The parcel arrived in this kind of foam. The packaging is like this, because... It's a fragile thing inside. Namely, a sensor for a mobile phone. I will replace it with one that was accidentally broken. It fell and broke, so I ordered myself a new touchscreen and will try to replace it myself and not contact any service center. I ordered from Aliexpress. Replacing a touchscreen with your own hands is quite a feasible task.

And so, we open it. This is the packaging. Two screwdrivers, why? And, in fact, the touch element itself with front protective glass. Then you can start replacing. To do this, you need to disassemble the smartphone, unscrew all the screws and get to the necessary element.

After all the screws are unscrewed, we separate the parts of the case. Probably, for this you need to carefully pry off the joint on the latches with something. After removing the cover, you need to start disconnecting all the cables. This must be done carefully so as not to damage anything, tear off or damage the smartphone. Some elements can be installed with something like double-sided tape, because... We must be careful and do not jerk sharply. For example, my bore buttons were installed this way. They were disconnected by carefully prying them off with a utility knife.

After disconnecting the board, we proceed to removing the old broken touchscreen. I had it glued on with double-sided tape, I think it’s the same in other models. We pry it off and start tearing it off. It is unlikely that it will be possible to save it, and there is no point.

After we have removed the old broken sensor element, we proceed to prepare the new one for installation. To do this, we remove the remaining adhesive elements at the installation site and then remove the protective films from the installation side of the new sensor element. Let's start installing it in place.

Once the sensor is installed, we can begin reassembling the device. We install all cables and connectors in place. We make sure that everything is installed as it was before disassembly.

Articles and Lifehacks

In this article we will try to briefly give an idea of ​​this procedure. When needed replacing the sensor on the phone? Why do most service centers claim that replacing it is impossible without replacing the screen? Is it possible to change the sensor at home and how? Let's try to answer these questions.

What do you need to know about replacing the sensor on your phone?

Often, even knowing how to do it, we think that the sensor and the front panel of the mobile device are not connected in any way. If such a panel is broken, we will have to replace the sensor.
If the sensor is broken, but is still working, do not think that repairs will not be needed. Sooner or later it will still fail, and therefore there is no need to hesitate. Efficiency is also important because replacing the sensor and screen in the future most likely will not help.

The most advanced models of mobile devices today have a rather complex design. The screen of the device consists of glass, a touchscreen (sensor) and a display. The peculiarity is that the module has a solid structure and all components are connected. This means that the screen will have to be replaced along with the sensor. Let's figure out how to replace the sensor along with the display on a phone using the example of the One V T320e device from HTC.

Instructions for replacing the sensor on HTC One V

So, we have a One V T320e mobile device with a broken screen. It is worth noting that this is not at all the reason. The gadget will have to change both the display and the sensor. Today, all this can be purchased as a set in any online store.

Let's start disassembling the device. On the rear panel, remove two special elements secured with latches. This is very easy to do.

Next, take a screwdriver and begin to unscrew the bolts. Remove the protective element at the top. We try to do this as carefully as possible so as not to touch the board. We lift the board (you will most likely have to glue it during assembly) and slowly “squeeze out” the screen with your fingers. You can also carefully pry it off using special tools.

Remove the back panel, unclip the battery connector and remove it. We lift the battery and remove it. Unscrew the bolts on the board, having previously snapped off all the connectors and disconnected the cables. It is recommended to do everything as slowly as possible so as not to damage anything.

After the board is removed, we connect a new screen to it for testing. We connect all the cables and thread them with our fingers. Connect the battery. Also, don’t forget about the power button connector. It needs to be slightly short-circuited, and then the device can be started in this semi-assembled form.
We are waiting for the device to load. We check how and how smoothly it works, go to the menu, and so on.

Now you can proceed to the final installation. We warm up our old display to remove it from the frame at a temperature of 200 °C. We remove the warmed-up display. The frame must be perfectly cleaned with a scalpel, since no dirt should remain on it.

After that, we cover the frame with double-sided tape to glue the screen. Don’t forget to re-glue the display guides, otherwise the backlight will not work correctly. We insert our new module into the frame. We also lay the guides correctly. Remove the tape from the cable.

We check how everything fits and gently press it. Now all that remains is to connect all the cables, place the board in place and assemble the mobile device.

Replacing the sensor on your phone with your own hands is not a very difficult task. In this article I will show you how to replace the sensor on your phone with a minimum of knowledge and a primitive set of tools.

Replacing the sensor on all devices, except those where the display and sensor are combined into one module, is performed in the same way. Therefore, this instruction will help a lot of people, even regardless of the phone model. There may only be differences during disassembly, but the technology and procedure will be the same for almost everyone.

They tried to close the door with this device (it was in the back pocket, and they closed the door with their butt). The door, of course, was closed, but the phone could not withstand this violence and happily shone with multiple cracks in the touchscreen

The display worked well, so only the sensor needed replacing.


You can, of course, take it to a workshop, but that’s not interesting and will be more expensive than replacing the sensor yourself :) Moreover, it’s absolutely not difficult.

What you need to replace the sensor on your phone

To replace the sensor we need a minimum set of tools and materials:

  • screwdriver
  • plastic card or something similar
  • regular tape
  • new sensor
  • tweezers
  • accuracy)))

Remove the back cover of the phone and take out the battery. We can say that half the work is done :)

We unscrew all the screws and put them in a secluded place so that they don’t get lost.

After this, use a plastic card to separate the halves of the phone case

Unsnap all the latches and remove the back of the case

Unfasten all interfering cables. On this phone there is only one - from the display

We check that nothing else is holding it anywhere and remove the phone board

put it aside

We see the sensor cable. Here it is primitive, so it is not even attached to the board, but simply pressed against it. This is a resistive sensor. You may have a capacitive one - it is larger and is usually connected to the board through a connector. How to disable them is described in detail in the article. I highly recommend reading it.

Now we need to peel off the sensor from the phone body. To do this, we pry it off and use our plastic card to guide it around the perimeter of the sensor

To make it easier, you can warm it up with a hairdryer.

Attention! Be careful when peeling off the sensor and take precautions because it is glass! You can cut yourself, a piece of glass can fly into your eyes, and the like!

This is the picture we got

Use tweezers to remove the remaining fragments and remove the work area from the glass.

Let's take a new sensor

It is covered with film on both sides. And without the film, they won’t exchange it under warranty if it suddenly turns out that it’s not working! Therefore, our task is to connect it for testing, and only then, after removing the protective film, paste it in its place.

It looks like this

That is, we assemble everything in the reverse order, but do not glue the sensor. We turn on the phone and, touching the sensor, check its operation over the entire area.

If everything works fine, then remove the film, remove debris from the display and press the sensor into place.

Here you may reasonably have two questions:

  • How and how to clean the display from debris and fingerprints?
  • How will the sensor stick?

The answer to the first question. Don’t even think about rubbing it with anything, you won’t achieve anything by doing this, you’ll only scratch it. The best way for me to clean the display is regular tape! Simply glue and peel it off sequentially over the entire display area and all dirt will remain on the tape and not on the display.

The answer to the second question. In this phone, the adhesive composition is applied to the device itself and it remains sticky for many years. The main thing is that after disassembly, dust and debris do not fall on it. But in most cases, the sensor is glued to double-sided tape, which is glued around the perimeter of the new sensor. You only need to remove the protective film or paper and glue the sensor to its rightful place.

Here, in principle, are all the simple steps to replacing your phone’s sensor. As you can see, everything is simple and fast.

If you have any questions, ask in the comments.

Peace to your home and strong phones!!!

Before you start repairing the tablet yourself, it is recommended that you familiarize yourself with the basic steps that will help you complete this job correctly.

Where to start replacing

Sometimes tablet owners have to deal with such an unpleasant problem as a cracked gadget screen. The touchscreen may break as a result of careless handling of the device. However, do not despair and panic. This problem can be easily solved. After all, you can replace the protective screen.

To do this, you can take your gadget to a service center, where repairmen will replace the damaged part. At the same time, there are cases when it is not possible to find a workshop nearby. In addition, the family budget does not always allow the use of specialist services. In this case, you can replace the glass in the tablet at home with your own hands.

Before you begin repair work, you must have the following tools on hand:


Important! Under no circumstances should you use metallic aids to avoid damaging or scratching the housing!

  • tweezers;
  • stationery knife;
  • soft fabric;
  • The screwdriver is usually a Phillips-head screwdriver.

When all the necessary funds have been collected, work can begin.

To disassemble the tablet, you must follow the following rules:

  • First you need to unscrew the bolts that are located in the end parts of the tablet, if any.
  • To detach the cover from the device body you will need a plastic card. With its help, you should lightly pick up the case itself and run it around the entire perimeter of the gadget.
  • The lid and the body are connected to each other by a cable that cannot be easily pulled out.

To do this, you need to open a special connector:


  • After this, you should rewrite on a separate sheet:
  1. markings on the cable;
  2. number of pins

Selection of glass model

The next step is to select a glass model.

It is worth noting that in a regular store it is unlikely that you will be able to find glass for tablet screens on sale. To do this, it is better to look into a specialized online store. It's even much more convenient. After all, you don’t need to go anywhere to make a purchase. In addition, the goods can be delivered directly to your home if you arrange courier delivery.

So, we find the necessary Internet portal. To order the correct model of protective glass, it is best to talk to the seller. An experienced manager will always be able to tell you which touchskin is best to purchase for a specific tablet model.

Once a new touchscreen has been purchased, it is worth checking that it is not damaged. After this, you can proceed to the next steps to repair the tablet.

We replace the touchscreen:


Assembling and setting up the tablet

After all the steps have been completed, you can begin assembling the tablet in reverse order.

After these simple steps, you can use the gadget as before.

Cost of replacing glass on a tablet

On average, the cost of touchscreens on the market varies from $12 to $70. At the same time, for older tablet models, glass will cost an order of magnitude cheaper than for new gadgets.

In addition, it should be taken into account that some tablet models, for example from the manufacturer Acer, come with touchscreens complete with a matrix. Thus, the price of the matrix must be added to the cost of glass. A similar set will cost from 50 to 120 dollars. In this case, the matrix itself will cost from 15 to 70 dollars.

If something irreparable has already happened and the glass is cracked, it is not recommended to delay repairs even if the touchscreen is still working.

Since the screen consists of:

  1. matrices;
  2. touch screen - touchscreen.

Most often it is the touch glass that breaks, but the matrix remains unharmed. Further use of the gadget may damage the matrix. In this case, we will have to replace both elements, and this is an extra cost that we do not need.

When replacing the protective glass yourself, you should pay attention to these recommendations:

  • Before gluing the touchscreen, you must first make sure that it is in working order, since re-gluing will take a lot of effort and time;
  • All actions must be performed very carefully so as not to damage the device.

How to protect your tablet screen from damage:

  • do not drop the device;
  • It is not recommended to leave the gadget on chairs or sofas, as you can accidentally sit on it;
  • glue a special protective film to the screen;
  • purchase a case with a hard surface;
  • protect the gadget from temperature changes, as this can cause the glass to crack.

By following these simple tips you can protect your screen from damage. At the same time, extend the life of the device. If the touchscreen is already damaged and there is no way to contact a service center, using these recommendations, you can fix the problem yourself and save money.

Unlike desktop computers, functions and programs in tablets are controlled by lightly pressing the fingertip on the screen at the desired point. The tablet reacts to touch thanks to a thin transparent glass plate superimposed on the display screen. When you press on the glass (touchscreen), depending on the type of sensors, the resistance, inductance or capacitance of the mesh applied to the glass changes and thus the tablet receives instructions for a specific action.

The touch glass is very thin, but strong enough to break with your finger. But if the tablet is dropped on a hard surface or hit with a sharp object, the touch screen cracks, which is what happened with the glass of the children's MonsterPad tablet shown in the photograph.

Checking the tablet's functionality using the mouse

The image on the screen was uniform without defects or distortions. The tablet remained operational, since when you pressed the Power button, a window popped up with a menu to turn off the tablet, but it became impossible to control its operation by touching the screen with your finger.

To fully check the functionality of the tablet, and the ability to turn it off before repair, it was necessary to connect a mouse to the Micro USB connector located on the side of the tablet. Mice usually have a USB connector. Therefore, I had to buy a USB-Micro-USB adapter.


When a mouse was connected, the tablet system automatically detected it, and an arrow-shaped mouse cursor appeared on the screen. Diagnostics showed that the tablet’s electronics are in good condition. Therefore, to repair the tablet, it is enough to replace the touchscreen with your own hands. After diagnostics, the tablet was turned off using the mouse.

While waiting to purchase a touchscreen, it is necessary to keep the tablet's battery charged, since deep discharge sharply reduces the tablet's battery life.

Where can I buy a touchscreen for a tablet?

The search for a store to purchase a touchscreen for a children's tablet MonsterPad at a minimal cost led to the website of the time-tested Chinese online store AliExpress. The site presented a large assortment of sellers of touchscreens for the MonsterPad tablet.


A seller with a large number of positive reviews and a high rating with an average price and free shipping was selected. When choosing a touchscreen, pay attention to the presence of double-sided tape on it. If the screen is without adhesive tape, then replacing it will be complicated by the need to purchase such adhesive tape, cut it and secure it.

If you can’t find a touchscreen by the name of the tablet, you can try searching by its markings, which are usually applied to the flat cable running from the touchscreen.

The touchscreens of many tablet models are interchangeable. The main thing when choosing is to pay attention to the type of sensor and its diagonal size, expressed in inches. For example, the MonsterPad requires a 7" touchscreen.

The resulting parcel was a large, compared to the size of the touchscreen, polystyrene box completely wrapped in adhesive film. It is convenient to open such packaging by cutting the film with a knife along the line of connection of the box halves.

The touchscreen was removed from the packaging and carefully inspected for defects. Everything was in perfect condition. Trying on the glass on the tablet confirmed the size matches. To check its functionality, all that remains is to disassemble the tablet and connect the touchscreen to the motherboard.

How to disassemble the MonsterPad children's tablet

Before starting to repair the tablet, to avoid scratches on its case and display and dust getting between the display and touch glass, you need to wipe the table with a damp cloth and cover its surface with a soft, lint-free cloth. The only tools you need are a knife and a couple of small screwdrivers with a Phillips and a flat blade. After preparing the workplace, you can begin repairs.

The MonsterPad children's tablet is easy to disassemble thanks to the screw fastening of the back cover. Using a sharp tool, remove the four plug legs glued with adhesive and unscrew the four screws using a Phillips screwdriver.


Then, even without the help of a plastic card, grab the case halves with your fingernails in the area where the tablet's power button and connectors are installed, and carefully move the halves apart. The power and sound volume buttons must be immediately removed and set aside so that they do not get lost or scratch the tablet screen if they fall under it.


The tablet has been disassembled sufficiently to begin replacing the touch glass. All that remains is to remove the cable coming from the touchscreen from the connector. In the photo the connector is in the far right corner.

If the tablet was disassembled to replace the battery, then its type is clearly visible in the photo. To replace the battery, you first need to unsolder the red and black wires coming from it from the motherboard and carefully remove it, overcoming the adhesion force of the double-sided tape.


To release the touchscreen cable, you need to use a screwdriver blade to move the clamps a couple of millimeters in the direction indicated by the red arrows in the photo. After this, the cable can be removed from the connector without force.

How to check the touchscreen before installing it in a tablet

After removing the back cover from the tablet, it became possible to test the new touchscreen for functionality. To do this, without removing the protective film, you need to place a new touch screen on the broken one, carefully turn the tablet over, and observing the numbering of the cable, insert it into the connector on the motherboard and return the latches to their place. Then turn the tablet over with the display facing up and turn it on using the power button.

After downloading the software, you need to tap on any icon or just work a little on the tablet. If there is a reaction on the display when touching and scrolling through pages, then everything is in order and you can start replacing the broken glass. Before starting the repair, you must turn off the tablet with the power button and disconnect the cable of the new touchscreen from the connector.

How to remove a cracked touchscreen

To remove a cracked touchscreen, use the end of a knife to pry it at any of the corners and try to lift it up.


In the MonsterPad tablet, the glass was glued weakly; there was no need to even heat the glued area with a hairdryer. The force of the fingers was enough to peel it off. The main thing is not to rush and perform this operation very slowly and smoothly.

Preparing the tablet frame and installing the touchscreen

After removing the cracked touchscreen, use a rag soaked in alcohol to degrease and remove any remaining adhesive from the frame.


Fortunately, the cracked glass did not crumble into pieces and there was no need to use a vacuum cleaner or hair dryer to blow off the small fragments. For the same reason, it is not recommended to scrape off glue residue with a tool.


To ensure that the cable did not interfere with the positioning of the touchscreen when gluing, a piece of polyvinyl chloride tube was inserted next to its release hole, as in the photo.

In the next step, the protective film was removed from the touchscreen from the applied adhesive layer to the edges.


All that remains is to tuck the cable into the hole in the tablet frame, rest the corner of the touchscreen near the cable into the notch of the frame and slowly attach it to the frame, controlling the accuracy of the placement in the opposite corner diagonally.


The touchscreen fit into the recess of the frame exactly, without gaps or displacement on the first try. There is no need to press the glass tightly at this stage of repair. It is advisable to do this after fully assembling and checking the operation of the tablet.



The cable is long enough, which is convenient for installation. However, to prevent the cable from breaking if it gets caught between the covers when they are closed, it must be folded in half and pressed a little, avoiding sharp bends.

All that remains is to install the pushers of the buttons for turning on the tablet and adjusting the sound volume and snap the back cover to the base of the tablet. Screw in the four self-tapping screws and install the removed plugs on them.


The independent repair of the tablet was successfully completed, it began to work and look like new, and the child can play his favorite games again. Now, I believe, he will be more careful with his tablet and other gadgets. I did not remove the protective outer film from the touch screen; let the owner of the tablet remove it and be the first to tap (touch) the surface of the screen.

I hope that the step-by-step instructions provided will help any home craftsman, even those who do not have experience in repairing such devices, cope with the repair of a tablet or smartphone.

The cost of replacing the tablet's touch glass with your own hands was less than 10% of the original cost of the tablet.
