This post is for Samsung Galaxy Tab 4 T231 Earpiece problem solution. It works on Samsung T231 . Earpiece which some people also call speaker is used for listening to calls. It is placed on the Top front side of the phone.
If you have damaged the Earpiece soldering prints I have marked all the Samsung Galaxy Tab 4 T231 Earpiece Jumper Ways in the next diagram. Please be very careful while doing any kind of hardware solutions specially if you don’t have much experience.
The first step that should be done is to check speakers themselves, if the speaker issues a small voice, the speaker can be sure there is a dirt hole, try to clean it., to clean it does not resolve the issue try the next step.
The second step try changing the speaker, if the speaker is certain that the cause of the problem, simply by replacing the speaker has a problem could be solved, if it does not work out try the next step.
The third step try to check the speaker lines as shown below, check one by one lane and a resistor connecting the speaker lines, if there is a path-breaking try doing jumpers with caution and care.
two terminals of the speaker from the connector are connected to diode.
In order to troubleshoot, all you have to do is to follow the following steps:
Put jumper if it is faulty, as one of the reasons for this problem is that the phone heavily dropped or water damage.
Check the diode by using multi meter, if it is faulty then change it.
