Introdução
If your wired audio devices don't seem to be connecting to your Samsung Galaxy Tab A8 properly, or at all, use this guide to replace the headphone jack. Make sure to troubleshoot any possible causes and solutions before beginning this guide.
The headphone jack is how you can connect almost any wired audio device to your tablet, allowing you to play sounds to an external source instead of the tablet's built-in speakers. The jack can become damaged or dirty over time, and requires cleaning and maintenance to extend its lifespan. If no amount of cleaning or debugging the software seems to fix the problem, then replace the jack by following these steps below.
-
-
Fully power off the device.
-
Orient the screen so it is face-up.
-
Apply anti-clamp or other suction device to apply constant upward force on the screen.
-
Heat the screen to soften the adhesive with a heat gun or blow dryer. Be sure to heat all sides as evenly as possible.
-
-
-
Use plastic opening picks, or a Jimmy if necessary, to remove the adhesive and get under the screen.
-
Using the plastic opening picks, move around the screen slowly, one corner at a time. Every few inches, leave an additional opening pick behind where you are working to hold the screen open while continuing to remove the adhesive.
-
-
-
Continue to pry the screen off with the opening picks, using additional tools if more leverage is required.
