How to fix it: the sensor on the phone does not work

The push-button mobile phones have been replaced by ergonomic touch devices. What has changed with the new technology? Yes, almost everything related to the functionality of management. Therefore, a tricky situation when the sensor on the phone does not work requires immediate resolution. Moreover, in some cases, the user has every chance to make repairs on his own. However, we read about this and much more below.

Why did the sensor stop working?

Phone sensor not working

There can be an incredible number of reasons. Despite the high manufacturability of the touchscreen, in most cases it is a fragile and rather "finicky" control element. The functional abilities of such a modern "miracle" are completely dependent on a variety of influencing factors:

  • weather conditions,
  • mechanical damage,
  • entering conductive liquid.

Software failure, spontaneous system failure can also be the culprit of what does not worksensor on the phone. Of course, all these shortcomings are conditional, because it is the human factor that plays the main role in the life of the mobile device used. Specifically, the performance of the device and its efficiency in operation depend on our actions.

Typical Touch Screen Problems

Sensor stopped working

Mechanical damage most often leads to various breakdowns. Falling and deforming are record holders of the common excuse: “I didn’t do anything, I just rode in a crowded minibus” or “It’s not my fault that he is so slippery.” The consequences of impact and excessive pressure on the device can be different. From an innocent chip on the case cover to the spidery pattern of a split display. The case can "be patient", but the touchscreen and the screen will need to be replaced. If the sensor on the phone does not work, you should pay special attention to the structural parts of the mobile phone. In the case when the body part of the device moves away from the touchscreen and you visually see the resulting gap or find that the control panel has shifted, you need to install the parts in place. Sometimes a smartphone loses its sensory performance due to a small amount of liquid that has got inside the gadget. And often you don’t even know how water ends up in the depths of the device. Although you should know that the condensate will pick up the most unfavorable moment to show its destructive abilities. Check pads and connector sockets for oxidation. Physical Defects:screen flickering, image distortion and other non-standard manifestations in the operation of the phone may indicate that the device needs urgent repair. Procrastination and delay in getting professional help is not in your best interest…

Sensor not working well

What you can do: on your own is not counterproductive

If the sensor on the phone does not work well, first of all, calibrate the touchscreen. Usually this function is available in the main settings window of your device. Such actions are carried out when the device is clearly in good condition, when the case is intact, no signs of deformation and oxidation are found, and the sensor reflects the glare of light with an impeccably smooth surface. With not entirely rosy forecasts, you have to reincarnate as a mobile device repair engineer. Since the subsequent actions require certain skills and specific knowledge.

Oxide removal and touchpad positioning

Arm yourself with a special (mobile) tool: Phillips and flat screwdrivers, an unnecessary plastic card (bank or other). Have rubbing alcohol, a clean toothbrush, eraser, and regular table napkins ready.

  • Before disassembling the device, watch the video on dismantling the phone. To do this, just enter the model of your device in the search engine and add disassembly / assembly.
  • Be careful when separating parts of the case, there is a high risk of breaking the connecting elements of the device: cables, wires, antenna and other attachments.
  • Draw a diagram of your device and screwslay out according to the drawn drawing.
  • Poor phone sensor
  • Wipe accessible places of oxidation with alcohol, then with an eraser, after with a napkin.
  • Toothbrush should be used for general cleaning of corroded circuit board and phone components.
  • Contact pads for connecting cables, especially the touch screen connector, treat with alcohol and remove plaque with an eraser. The surface of the elements should ultimately be clean and dry.
  • Displacement or flaking of the touchscreen from the case is most often the reason why the sensor of your device does not work well. Therefore, to put it in place, use a household hair dryer. On the inner edges of the heated (do not overdo it) wheelbarrow, the adhesive base will soften, and you can return the sensor to its original place.
  • Assemble the device carefully and carefully, observe the order of installation and do not forget to screw the fixing screws into place, and also install the protective shielding elements removed from the chips.
  • Phone sensor not working

In conclusion

In case of a favorable outcome of all your manipulations, your touchscreen should work. If everything remains unchanged and the sensor on the phone also does not work, then only the replacement of this component of the control system will help you. What is not recommended to do at home. Therefore, you can not avoid a visit to the workshop. Take care of your sensor!
