Step-by-Step Battery Replacement Guide

Step 1. Power Off and Prepare the Tablet

Turn off the Samsung Galaxy Tab A completely before starting.

Step 2. Remove the LCD Screen

Heat the front screen gently to soften the adhesive.
A heating pad is the safest method, but a heat gun or hairdryer works too.

Take your time—do not bend or puncture the battery.

Add isopropyl alcohol or more heat if needed.

Lift and remove the old battery.

Step 15. Reassemble the Tablet

Clamp the back housing and mid-frame together, ensuring all clips lock.

Insert all 23 screws.

Step 16. Reconnect and Test the LCD

Plug in the LCD connector and power on the device to confirm everything works.

Step 17. Secure the LCD Screen

Apply new adhesive around the edges using pre-cut adhesive or B7000 glue.

Slide the screen from bottom to top into place.
Press around the edges to secure it.
