Proximity sensor replacement

When the proximity sensor of a smartphone has problems, it is necessary to replace the component. This sensor is responsible for detecting the presence of the user's face during a phone call, turning off the screen to avoid accidental touches.

To replace the proximity sensor, it is necessary to disassemble the smartphone and access the motherboard. It is important to have technical knowledge and ability to perform this procedure, as any mistake can further damage the device.

First, it is necessary to remove the back cover of the smartphone and remove the battery. Next, you need to remove the screws that secure the motherboard and unhook the flexible cables that connect it to the rest of the device.

With the motherboard loose, it is possible to see the proximity sensor, which is usually located next to the front camera. It is necessary to remove the old sensor carefully, detaching it from the motherboard and removing any residue of glue or adhesive that may be present.

Next, you need to install the new proximity sensor, fitting it to the motherboard and fixing it with glue or an appropriate adhesive. It is important to follow the component manufacturer's instructions to ensure correct installation.

After installing the new sensor, it is necessary to reassemble the smartphone, connecting the motherboard to the flexible cables again and fixing it with the screws. Finally, you need to replace the battery and the back cover of the device.

It is important to emphasize that the replacement of the proximity sensor must be carried out by a trained professional, as it is a delicate procedure that requires technical knowledge and skill. In addition, it is necessary to use quality components to ensure the proper functioning of the smartphone after maintenance.
