Replacing the light sensor is a common maintenance on smartphones, especially when the original sensor is damaged or not working properly. The light sensor is responsible for automatically adjusting the brightness of the smartphone's screen according to the ambient light, making viewing more comfortable for the user's eyes.
Before starting to replace the light sensor, it is important that the technician has knowledge about the internal structure of the smartphone and has the appropriate tools to carry out the procedure. In addition, it is necessary to purchase a light sensor compatible with the smartphone model in question.
The first step to perform the replacement is to turn off the smartphone and remove the back cover. Then you need to disconnect the battery to avoid short circuit risks during the process.
With the battery disconnected, the technician must locate the light sensor on the smartphone's motherboard. It is usually near the front camera or speaker on the device. It is important to be careful when handling the motherboard to avoid damaging other components.
With the light sensor identified, the next step is to remove the old component using tweezers or similar tools. Then the new sensor must be carefully fitted into the proper location.
