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

In place of the push-button mobile phones came the ergonomic sensory devices. What has changed with the application of the new technology? Yes, almost everything that is associated with the management functionality. Therefore, a tricky situation, when the sensor on the phone does not work, requires immediate resolution. And in some cases, the user has every chance to repair himself. However, we read about this and many other things below.

Why did the sensor stop working?

The reasons can be an incredible set. Despite the high adaptability of the touchscreen, this is in most cases a fragile and quite "fastidious" control element. The functional abilities of such a modern "miracle" are in full dependence on the various influencing factors:

• Weather conditions,
• Mechanical damage,
• Hit of a conductive liquid.

Software failure, spontaneous system failure can also be responsible for the fact that the sensor does not work on the phone. Of course, all these drawbacks are conditional, because it is the human factor that plays the main role in the life of the mobile device used. It depends on our actions depends on the operability of the device and its efficiency in operation.

Typical touch screen faults

Mechanical damage is most often caused by various breakdowns. Falling and deformation are original record holders of the widespread excuse: "I did nothing, just drove in a crowded minibus" "or" I'm not to blame for being so slippery. " The consequences of the impact and excessive pressure on the apparatus may be different. From the innocent splintering on the case cover to the cobweb pattern of the split display. The case can "suffer", but the touchscreen and the screen will need to be replaced. If the sensor does not work on the phone, it is worth paying special attention to the structural parts of the mobile phone. In the case where the body part of the device moves away from the touchscreen and you visually see the gap formed or found 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 gets inside the gadget. And often you do not know how water is in the bowels of the device. Although you should know that the condensate will pick up the most unfavorable moment to show its destructive abilities. Check the contact pads and sockets of the connectors for oxidation. Physical defects: flickering of the screen, distortion of the image and other non-standard manifestations in the work of the phone can say that the device needs emergency repairs. Delay and delay with professional help is not in your best interest ...

What you are capable of: independently - does not mean counterproductive

If the sensor on the phone does not work, first of all, calibrate the touchscreen. Usually this function is available in the main window of your device settings. Similar actions are carried out at obvious serviceability of the device when the case is intact, traces of deformation and oxidation are not detected, and the sensor reflects the glare of the light with a perfectly smooth surface. With not very bright forecasts, you will have to reincarnate as an engineer for the repair of mobile devices. Since subsequent actions require certain skills and specific knowledge.

Elimination of oxide and positioning of the touch panel

Armed with a special (mobile) tool: a cross and flat screwdrivers, an unnecessary plastic card (bank or other type). Prepare alcohol, a clean toothbrush, an eraser and ordinary table napkins.

• Before disassembling the device, watch the video on the phone's dismantling. For this purpose it is enough to register in the search engine the model of your device and finish the disassembly / assembly.
• Be careful while disassembling parts of the case, there is a great risk of breaking the connecting elements of the device: loops, wires, antenna and other attachments.
• Draw a diagram of your device and align the screws according to the drawing.
• The available places of oxidation wipe with alcohol, then with an eraser, after a napkin.
• The toothbrush should be used for general processing of corroded board and structural elements of the phone.
• Contact areas for connecting loops, especially the connector for the touch screen, handle with alcohol and remove the plaque with an eraser. The surface of the elements, in the end, must be clean and dry.
• Displacement or flaking touchscreen from the body is most often the cause, because of which the sensor of your device does not work. Therefore, to put it in place, use a household hair dryer. On the inside edges of the preheated (do not overdo it) glue the adhesive base will soften, and you will be able to return the sensor to its original position.
• Collect the device carefully and carefully, observe the order of installation and do not forget to screw in the fixing screws, and also to install the protective shielding elements removed from the microcircuits.

Finally

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