Android devices come with a built-in speaker that can be used to listen to music, watch videos, or take phone calls. However, if your speaker is not working properly, you may be able to fix it. To start, open the “Settings” app on your Android device. From here, tap on “Sound & notification.” Next, scroll down and tap on “Speaker.” If the “Speaker” option is not present, then your speaker may not be enabled. To enable the speaker, tap on “On.” If the speaker still does not work properly after following these steps, you may need to replace your device’s speaker. To do this, first remove the battery from your device and then unscrew the back cover of your device. Once you have removed the back cover, you will see a board with several ports on it. One of these ports is likely for a speaker; use a Phillips screwdriver to remove the screw that holds it in place and then replace it with a new one. ..
