Eject the SIM card and microSD card tray.
 
Step 3 (Samsung Galaxy S8+ Rear Glass Panel)
 
The Galaxy S8+ rear glass panel is glued on solidly and is a tight fit within the frame. Apply heat to soften the adhesive.
 
With the precision knife create enough space to insert a playing card.
 
Attack the sticky adhesive and carefully dislodge the rear glass panel from the chassis.
 
You will need to detach the very short fingerprint reader cable from the motherboard before completely moving the glass out of the way.

Use the spudger to help free the Galaxy S8+ fingerprint reader from the adhesive securing it to the rear panel.

Remove the following 15 Phillips screws.
 
Pry up the upper antenna assembly that is combined with the NFC and wireless charging panel.
 
Easily lift out the lower antenna assembly that includes the single speaker.
 
Step 6 (Samsung Galaxy S8+ Battery)
 
The S8+ battery is well wedged and adhered in place. Use a playing card to muscle it free from the adhesive securing it to the midframe.
 
After a brief struggle out pops the 3.85-volt, 3,500 milliampere-hour (mAh) Samsung Galaxy S8+ battery.
