Mobile phone models are constantly updated. And new models appear almost every two weeks. Are improving different functions and opportunities expand. Mobile usability is also very important for modern users. This is why touch screen phones are very popular.
The advantage of a touch screen on a phone is that the screen size is larger than a regular one, which means its menu is more accessible. In addition, various multimedia applications are more convenient to use on an extended screen. Controlling your phone and its functions using your fingers is also attractive to many people.
However, not all people have mobile phones with touch screens. After all, we cannot change our phone every month as new models are updated. And if you have a regular mobile phone, then the question may arise of how to make the phone touch-sensitive.
I tried to answer this difficult question Nokia company. In December 2007, a pen with Bluetooth module, which appeared on sales in the CIS countries. With the help of a pen it became possible to write on regular phone, supporting Bluetooth function phone numbers, addresses, any notes, without using a regular keyboard. This pen can also write on regular paper. However, due to the high cost of $240-280, the pen was not widely used. Indeed, in our time, for such a price it is easier to buy a phone with a touch screen rather than treat yourself to such an accessory device.
How to make the phone touchscreen differently - perhaps this question will be answered by some brilliant inventor who will figure out how to simply and, most importantly, inexpensively upgrade the phone to a touchscreen one. However, to date no such invention has been made. Manufacturers of new mobile phones are working on technologies for manufacturing new models with touch screens. But there is practically no development on how to make a regular phone a touchscreen one. And if you are interested in such an invention, then you can try to come up with, and possibly patent your invention.
Touch phones are undoubtedly pleasant devices that please the eyes and fingers. Is it true that an ordinary push-button telephone, even a black and white one, can be made touch-sensitive? This sometimes seems like a myth, but strangely enough it is true. What methods have people come up with just to be like those who have a fancy phone, and one of these methods turned out to be effective. It may not be strange, but you don’t need a lot of money and time to create a touch phone. Let's not stand on ceremony and find out how to make a regular phone touchscreen? If someone thinks that only some models can be turned into a touchscreen phone, then I will say right away that this is not so.
In fact, you can absolutely any old or new model turn your phone into a touchscreen device. And so, as many have guessed, the phone itself cannot be turned into a touchscreen device, this can only be done with a screen, but now we’ll talk about how to do this without breaking it. First you need to choose one or another phone that you would like to make touchscreen; for the first time it is better to take old phone, because if something happens it won’t be so bad. In order to learn how to make your phone screen touchscreen, you will need three things: the phone itself, hairspray, and a clean cloth.
It is better to take each of the ingredients with caution. For example, as mentioned above, you need to take an older phone or at least not an expensive one. You can take “Sensitive” hairspray, you can use others, but this one is proven, so if possible, it’s better to take it. You also need to take a clean cloth, or even better, use a cotton swab, it will be more reliable. These ingredients have been tested on the phone, so if you decide to learn how to make a laptop touch-sensitive, then it’s better to read something else. Apply hairspray to a cotton swab or cloth, then apply it with gentle but even movements on the glass panel of your phone.
Apply until the varnish dissolves. Then, after a couple of seconds, a thin film should form on the phone, which will turn an ordinary phone into a touchscreen one. This method is really simple and effective, but there are comments on the Internet that refute this method. This may be due to the fact that people are using low-quality varnish. After such experience, the question of how to choose a touchscreen phone will disappear by itself. You can make a touch phone out of any phone, you just need to follow the instructions and choose the right product.
Touchscreen phones are popular not because they are multifunctional, but because they completely eliminate the ability to work with buttons. Now this opportunity can be provided on a regular phone. It is not recommended to try this method on a computer or laptop, since the devices are very expensive and if something happens, no one except you will be responsible for them. How to do it and how to enable it touchpad on a computer, you can learn from videos posted on the Internet.
This is also a pretty good invention that helps simplify the user's work. In conclusion, we can say that a simple phone will cost much less than a touchscreen one, and if the problem is only switching functions with your finger, then this problem can be easily corrected with varnish, but if preferences lie on design and functionality, then in this case even varnish hair is powerless.
Grandma's phone is a cell phone with large, large buttons, big screen and increased ringer volume for people with low vision.
The name “granny phones,” which aptly dubbed phones for the elderly, has firmly entered the modern lexicon. And if previously elderly parents and grandparents received mobile phones mainly “inherited” from advanced offspring who decided to change their phone model to a more modern one, in recent years mobile phone manufacturers have been actively developing and producing grandmother phones - models specifically for this target audience.
A mobile phone is no longer a luxury item, but an absolute necessity.
And for an older person, the presence/absence of a cell phone can literally become vitally important: for example, it became bad, but the landline number does not work, or even this happened in a summer cottage, where the nearest doctor is 40 kilometers away! You never know the possible situations, not to mention the fact that the very opportunity to freely communicate with your children at any time will have a calming, almost therapeutic effect on an older person.
But in order for you to make the right choice and your gift not to become useless and inconvenient for your grandmother, who has poor vision, or for your grandfather, who is angry because he cannot figure out “how to use this thing,” it is important to understand exactly what requirements a mobile phone should have telephone for an elderly person. In principle, it won’t take long to list all the main necessary features and features of the “granny phone”:
- the largest and most comfortable keyboard buttons;
- accessible, understandable, one-level menu;
- minimum required set of functions;
- loud call ringer;
- ability to connect a headset compatible with a hearing aid;
- presence of an “SOS” button, which provides emergency call a predefined number or several numbers;
- It is desirable to lock the keyboard with a separate key or lever;
- monochrome display with clear, large, readable font, which will be convenient for people with low vision;
- the ability to listen to the radio without headphones;
- low, “budget” price (to convince a relative to use the phone and not put it in the sideboard as too valuable a thing).
Which granny phone you choose for your elderly relatives is a matter of taste and your financial capabilities. But when making your choice, do not forget that our grandparents need more than just a dialer.
Feature phones based on Android 2018
And although they don’t need extra functionality, it would be very nice to put your favorite melody on your phone. By the way, some quite “advanced” grandparents successfully master the cameras built into the phone and “on full blast“They use them to photograph their beloved grandchildren or their pets, the fish they caught, or their dacha achievements. It’s nice to save such information “for memory”, and you can show it off to your neighbors very clearly.
Choosing a phone is a responsible process that requires a certain approach. You need to be very careful when choosing a phone, because it is unlikely that you can change it every week.
Phones
Today on the store counter you can see various phone models that differ from each other not only in color and functions, but also in the presence or absence of buttons. On the market in this moment Most of all it is touchscreen models of phones, but push-button ones are quite enough. In this regard, you can often hear the dilemma - which phone to choose, touch or push-button?
Phone selection
The final choice must be made based on many different nuances. First of all, you need to understand whether you can live with the new screen and also work well with it. Of course, almost every person has a fear of the new and, first of all, this is due to natural instincts. For the older generation, it is better to choose push-button phones, since working with them is much easier (calls and SMS can be sent by simply pressing buttons), while a touchscreen phone still needs to be sorted out.
The second reason is directly related to the sensor itself, because it does not always work well, while the buttons always work as they should. Today there are two types of sensors: resistive and capacitive screens. Resistive sensors respond to any pressure. The first touchscreen phones had just such a screen. It is worth noting that such a screen had two films. When you clicked on the top one, a certain signal was sent, which was eventually read by the program. This kind of film was often scratched and dirty, because sometimes you had to press very hard on the screen. As a result, the phone lost its original appearance. The new generation of phones has a capacitive screen that reacts exclusively to current conductors (fingers, styluses, etc.). Such touch screen It's fairly easy to use (you don't have to press too hard with your fingers to get the phone to respond), but be aware that these screens have thin glass that can break.
The following reason for choice follows from the latter.
A person may drop a touchscreen phone.
How to turn a push-button phone into a touch phone
If its screen breaks, the phone will be impossible to use, which means that such phones must be treated very carefully. For the most part, push-button phones retain their native functions and if you need to call such a phone with a broken screen, then this can be done simply by pressing buttons.
The last thing is the inconvenience of using touch phones for people with large fingers. Most often, the touch screen is pre-programmed for a certain size of icons that cannot be changed (unless you reflash or use other special software), and if these icons are small, then you can click on other icons at the same time, which causes additional inconvenience.

IT Blog Touch Monitor
This article is about how to make a real touch screen monitor from a regular monitor.
I made a touchscreen monitor from a regular LCD 15 and the touchscreen itself.
Carefully! Lots of photos :)
So we have:
- 15″ monitor (I had Proview)
- crazy desire to get a touch screen
Let's get started.
First you need to take everything apart and see what's inside. To do this, unscrew the bolts. In my case there are only two, if the monitor is different, then there may be fewer or more bolts, but it’s easy to unscrew them.
After unscrewing, very often the front panel of the monitor still does not want to come off. This means you need to unlatch the latches. I can do this well with a screwdriver:
All. The cover was removed. We looked at the latches :)
Now we have a bare screen:
We pick it out of the case (don’t ask why, you’ll see for yourself right now)
They picked it out. We look, looking for empty spaces.
But now I’ll tell you why. At the very beginning of the article I said that we would install a touch screen. So, the touchscreen that I installed consists of the touchscreen itself (glass with a film glued to it) and a USB controller, which I also decided to stuff inside.
Here is the controller itself:
Quite small. A little more than 10cm in length, about 4-5mm in height.
The controller does not heat up, so I wrapped it with electrical tape just in case.
I glued it to the back with 2-sided tape. This tape will glue the controller to the case. Such fastening will be sufficient, since no force will be created on the touch-screen controller, so there is no need to fence anything extra.
Glue it to the body. It is advisable to glue it so that it does not stick out from behind the metal cover, but is level with it, since we still have to put the screen back :)
We remove the extra “ventilation grille ribs” of the monitor from below in order to bring the controller’s USB cable out. I did this with a regular soldering iron and scalpel.
We pass the cable.
how to turn a push-button phone into a touch phone
Since the kit includes a cable with filters (barrels), I had to cut off a few more plastic stiffeners.
To ensure that all this does not dangle during the installation process and to ensure that the cable is not accidentally pulled out of the connector when using our future touch panel, we secure the cable with plastic ties.
Now we proceed to installing the glass itself with the touchscreen. First, wash the monitor screen (which shows the picture) very carefully, because if you don’t wash it, it will be difficult to get to it, and we don’t really need stains “inside” the monitor! 🙂
After this, we glue it to the steel frame of the monitor screen Double-sided tape(car thin)
We glue the glass with the touch screen onto this tape. At first I had a desire to glue the glass over the entire surface, but after thinking about it, I abandoned this desire - it won’t fall out anyway (and there’s also a frame on top), but if you have to disassemble this structure, it will be very difficult to remove it from the car tape.
All that remains now is to connect the touch screen and the USB controller. A cable with a connector is used for connection. The cable is thin, so it can be “wrapped” around the screen and the base of the screen. So that it would not dangle, I also glued it.
It was very lucky that there was a mounting recess in the place where the touch screen cable goes. Now you don’t have to worry about the cable being pinched or anything else happening to it.
First test drive:
After I tried to put the front panel of the monitor back, it turned out that this panel presses on the touchscreen, thereby interfering with calibration.
I had to come up with this hack:
Well, I think the idea is clear - we make small protrusions so that the touch screen does not touch the front muzzle.
That's all. Finally, a video with the result of my work today:
As you can see in the video, I don’t have any problems with positioning at all and I don’t press the screen too hard either. Overall it works great.
P.S. Xeon will come soon and tell you exactly what kind of screen it is, where he got it and how much money it cost :) I really don’t know.

Xomep · Jan 24, 2013 · Comments on How to make a touch screen yourself, at home, are disabled
Many people know that there are touchscreen monitors: Matrix, Capacitive touch, Projected capacitive, Resistive, etc. Such touch screens cannot be assembled at home, but anyone can assemble an optical touch screen! So what do you need to collect with my own hands touch screen:
White, blank sheet of A4 paper (white matte acrylic)
Scissors
Webcam (the simplest 0.5)
Photo frame with glass, preferably the size of an A4 sheet of paper
An empty box, also preferably suitable in A4 size
With these tools we can create multi-touch.
Let's start assembling. We take an empty box (A4), draw diagonals from the inside at the bottom of the box, put a dot with a pencil at the intersection point, and punch a hole for the webcam. We strengthen the webcam. Next, insert a blank A4 sheet into the photo frame. We strengthen the sheet with clamps. We turn the photo frame with a sheet of paper upside down (the glass is facing the bottom of the box) and place it on top of the box, making sure that the webcam looks at the blank sheet of paper that we will place on top. The result is a “clean” box with a lid. Connect the webcam to the computer. Before connecting, make sure that the webcam drivers are installed on your PC!
To operate your touch screen, we also need special software.
1. So, go to the website CCV.NUIGROUP.COM, download (Community Core Vision) the program for your operating system.
3. Let's launch the program that controls the webcam. In the property tab, select black and white mode. Using brightness/contrast adjustments, we will ensure that only the tip of your finger is visible (not the entire part of your hand that the webcam sees) 4. Launch the mouse driver. For now it is deactivated. Let us remind you that the webcam must be running during operation!
How to make a push-button phone touchscreen?
Launching Community Core Vision. For proper operation systems must be enabled: Use camera, Track Dark, Send Tuio Oso. Next, we mark the working surface, and then it should be calibrated. Check the Flip Horizontal box and press the English letter “C”.
4 dots will appear on the monitor to assist you in calibration; press them on the surface of your touch screen. 6. Activate the mouse driver window, press the space bar. That's it, the job is finished! Now you can safely boast among your friends that you have assembled your own optical touch screen. Also, using the touch surface is very convenient to draw in Photoshop, Paint, Gimp!
The phone screen is the most vulnerable point. Indeed, it is very disappointing when, as a result of a fall or incorrect actions, such an important element as the phone screen becomes unusable.
Can I make the repair myself or do I need to contact a service center? What are you risking when self-repair We will look at the phone screen in this article.
iPhone screen replacement
Of course, if you need an urgent screen replacement on your iPhone 6 Plus and you are in St. Petersburg, it is logical to contact a specialized service center that can carry out qualified phone repairs.
However, replacing the screen on some iPhone smartphones has its own characteristics. The screen itself consists of a display itself that displays the image, a sensor that responds to touch and protective glass. All these elements are glued together with special glue.
If you dropped your phone and only the protective glass broke, but the display and touchscreen itself were not damaged, you can try to replace the glass at home. To do this, heat the glass with a hairdryer and carefully, using a knife, separate the glass from the screen, trying not to damage the touchscreen and the display itself.
Subsequently, the new glass is either glued using a special glue or installed with double-sided tape.
This “heartbreaking” moment is shown in more detail in the video at the end of the article; here we note that this entire process takes place with full responsibility for your actions and possible consequences for your favorite smartphone.
DIY repair
Repairing a phone screen with your own hands is not always practical.
How to fix a touch screen?
It is not always possible at home, because displays from different manufacturers have different designs, and sometimes it is better to entrust repairs to specialized service centers.
In conclusion, I would like to recommend purchasing official telephone numbers, protected by the official manufacturer’s warranty, it would be useful to familiarize yourself with information about consumer rights.
In any case, the possibility depends on you the right choice Your actions.

Master's answer:
It would seem that if the screen of a cell phone fails, then there is only one way out - throw away the old phone and buy a new one. However, there is no need to rush to waste money, because a damaged screen can be replaced yourself. This is actually not as difficult as it might seem at first glance.
Initially, you should determine whether the display is broken. If the image is distorted or several dead pixels, you need to contact a service center, whose specialists will be able to quickly eliminate these display malfunctions using special equipment. Well, if the image is completely absent, freezes or there is no response to pressing touch phones, in these cases, most likely, replacing the display is inevitable.
Turn off your phone completely by holding down the power button for a few seconds until the phone turns off. Remove back cover panel and remove the battery from the phone.
Using a Phillips screwdriver, unscrew all the screws that are located under the battery, remove back panel mobile phone and remove it side buttons. This way you have access to your phone's circuit board.
You will see a small cable that comes from the phone board and can be located at the top or bottom of it. Then, you need to remove the board from the phone, under which the reverse side of the LCD screen will be located.
Remove the screws that secure the LCD screen to the front of the phone. Remove the old LCD screen and replace it with the new one. Connect the cable to the screen and reverse order screw in all mounting screws.
Place the board in its original place and connect the cable. Secure the board with the mounting screws. Don't forget to insert the side buttons. After that, install and secure the back panel of the phone with screws.
Install battery and close the back cover of the phone.
Simple tips for those whose phone sensor does not work
This completes the screen replacement process. Turn on your cell phone and test the new LCD screen.
What to do if your phone's touch screen doesn't work? The touchscreen is broken.
Nowadays, ordinary push-button phones continue to be used mainly by people over 40 years old, and young girls and boys prefer to change their mobile devices to smartphones with a touch screen. Have cool smartphone with a touchscreen (Touch Screen - touch panel) - fashionable and stylish, and using it is much more convenient and enjoyable than push-button models. However, touchscreen devices must be handled with care as they may become unresponsive if dropped or exposed to liquids.
Accidental impacts, falls, shocks, moisture, hypothermia, overheating and pressure from solid objects directly impact the screen. to breakdowns touch display, which causes incorrect recognition of the touch of the sensor.
In case of partial or complete inoperability sensor The best thing a user who does not understand how their mobile device works is to take it to a service center. Professionals in their field will quickly replace or repair the touchscreen, and if the phone’s warranty has not expired, you can try to return it to the store. 
If you have some experience in repairing television and radio equipment, then you can disassemble a mobile phone with a broken touch screen yourself. You can repair a non-working sensor in cases where the body of the phone moves away from the touchscreen and you can visually see a barely noticeable gap. You can also restore damaged data yourself contacts in the phone's filling after water gets into it.
The most common in mobile phones are resistive and capacitive touch screens. A resistive touch screen consists of a glass panel and a flexible transparent membrane above it, on which a conductive (resistive) coating is applied.
Press your finger on the screen at this point panel and the membrane close, voltage appears on the electrodes and microprocessors automatically determine the coordinate using it.
Resistive touchscreens are not multi-touch. Realize real multi-touch, which allows you to track the coordinates of each press, is only possible in projected capacitive touch screens. The main advantages of projected capacitive touch screens are fast speed response to touch and more accurate determination of coordinates. Such high-quality multi-touch screens are used in iPhone and iPad tablets. If the multi-touch screen does not work on mobile device, then you shouldn’t try to fix it yourself. It’s better to entrust your expensive gadget to a specialist service center, which will replace its display with a new one.
Resistive and surface capacitive screens are simpler in design, and therefore if they break, you can try to fix the phone yourself. To do this you need:
1. Carefully inspect the touch screen of your phone to see if there are small cracks in it, which in 55% of cases lead to the device being “glitchy”. If traces of screen deformation are detected, its reliable operation can only be restored by replacing its display with a new one.
2. If the phone screen is intact, and the glare of light on it is displayed as a flawlessly smooth surface, then first try calibrate your mobile phone. To do this, go to “Settings” on your phone, then to “ Calibration" and click on it. This process is necessary to configure the touch display so that the phone responds to you the way you would like. Touch screen calibration should only be done in cases where the screen works but does not correctly recognize finger touches. For example, when you try to enter a number by pressing your fingers, another number appears on the screen. Calibration will help align the touchscreen and resolve these issues. 
3.
Crazy hands: how to replace the screen on your phone yourself
If the touch screen does not respond to touch at all, you will have to transform into a repair engineer cell phones. To do this, you should have a flathead and a Phillips screwdriver on hand, unnecessary plastic card, alcohol, eraser, toothbrush and napkins. Before disassembling your phone, enter your phone model into a search engine and add the word “disassembly” next to it. Next, watch the video or instructions dismantling your phone and, following it, carefully disassemble the body of your mobile phone into pieces. During the separation process, arrange the screws and other parts strictly according to the diagram so that during reassembly you do not have to look for them. Wipe the accessible areas of the phone first with alcohol, then with an eraser and a napkin. Use a toothbrush for general cleaning of boards that are susceptible to corrosion. Ultimately the surfaces of all details and parts inside your phone should be clean and dry.
4. Most often, the reason for the loss of functionality of the touchscreen is its displacement or peeling. To put the touchpad in place, you can use a regular hair dryer. The fact is that the screen is glued to the body with a special glue, which softens under the influence of hot air and releases the sensor, which makes it easy to put it in place.
You need to assemble a disassembled mobile phone very carefully, observing the order of screwing the parts and not forgetting to put all the protective shielding elements from the microcircuits strictly in their places.
