This guide will show the process behind replacing a daughterboard in the Samsung Galaxy Tab S3. This will be useful for fixing a broken charging port, as the port is soldered onto the daughterboard. It would also be useful if the home button, auxiliary, charging port and left speaker simultaneously stopped working, as these components all filter communications through the daughterboard to the motherboard for processing.

Do you need to remove the front display assembly to replace the daughterboard? From the images it appears you just have to go in through the back glass to do this job. Confused.
