What to do if the screen on your tablet is cracked and the sensor does not work

Tablet - a device that allows you to go online, call friends, play games, watch videos and listen to music. The gadget is very popular due to its compact size, light weight, fast Internet connection, availability and ease of use. Thus, a smartphone and a computer are combined in one device. Since the tablet is in operation for a long time, it is not surprising that its components fail. Most often there are breakdowns of the tablet sensor. There can be several reasons: electronics failure, poor-quality software, mechanical damage.

How to keep the tablet screen intact

Modern tablets are light in weight and very thin. Their screens are quite fragile. That's why you need to work with the gadget carefully. With a light fall, the screen will not crack completely, but small cracks may occur, and dust will start to clog in them. In addition, the screen can crack at a temperature difference, excessive pressure. To keep the device intact, you need to adhere to the following recommendations of experts:

• Do not carry the tablet in a bag without a protective case. Preference is better to give hard products.
• Glue a protective film on the surface of the screen and periodically change it. The service life of a good film is more than one year.
• Do not leave the gadget on chairs, armchairs and sofas.
• Do not give into the hands of people who have not previously used such a device, take care of it from small children and animals.

It is also important not to keep the tablet on your lap, sitting in the car, if you do not use it. You can forget it is there and stand up without putting the gadget away. It will fall.

Cracked screen, what to do?

If the tablet did not manage to save and when falling, it cracked, then you do not need to despair immediately. To begin with, experts recommend to understand what exactly broke and why the sensor does not respond to the touch of a finger. The tablet screen consists of a matrix that transmits the image and a glass screen, which is also called a touchscreen. If only the glass screen is damaged, it is easy to repair. You need to contact a service center, and the master will change the glass for a new one. Such a service will cost inexpensive. But if the matrix was damaged, then the repair will cost many times more expensive.

To determine whether the matrix was damaged when the tablet fell, it is quite easy. If it is in working condition, then the screen will show a crack, but the gadget itself will continue to work in the usual mode. But there is a risk that over time the damaged glass will damage the matrix. This, although rare, but it happens. In addition, the sensor on the broken screen will not work properly. That is why you should not delay your visit to the service center.

Of course, replacing the matrix will be expensive. In many models of tablets, the matrix and touchscreen are not disassembled, so both will have to be replaced. If the tablet's glass did not break during the fall, but the touchscreen stopped working, then, most likely, the loop came off and there was a microcrack. In this case, you will need to disassemble the device and check the signal. If the screen responds to touch only in a certain area, then it will be necessary to replace either the touchscreen or the module. The appearance of spots on the display also indicates its damage.

Since gadgets tend to fail at the wrong time, many users try to fix them at home. It is not recommended to do this, because such an undertaking is not always successful. At home, you can reboot the device, adjust the touchscreen or clean the screen from dust. It should be noted that to reduce the sensitivity of the touch screen can lead to inappropriate charger and poor quality of the protective film. It is better to entrust the repair to specialists.
