Follow this guide to replace the screen and battery assembly on your Samsung Galaxy S20+ with a genuine Samsung part.
This guide is written for the genuine Samsung screen and battery assembly. The assembly consists of the screen, battery, and frame together in one part. Be sure you have the right part before you begin the repair.
Before you begin, refer to the Samsung Self-Repair document for safety information.
If your battery is swollen, take appropriate precautions. Before disassembling your device, completely discharge the battery. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.
Note: Retaining water resistance after the repair will depend on how well you reapply the adhesive, but your device will lose its IP (Ingress Protection) rating.
Some images in this guide may show minor discontinuities. They should not affect the overall guide procedure.

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.
To reassemble your device, follow the instructions in reverse order and perform the opposite actions, e.g., "reattach" instead of "removing." Skip steps that use heating and prying, and pay close attention to the 📌 bullets as you work through the steps.
After you've completed the repair, download the Samsung Members App from the Galaxy Store or the Play Store, and Samsung Self-Repair document (beginning page 10) to make sure your device is fully functional.
Download the Self Repair Assistant on your device and follow the Samsung Self-Repair document (beginning page 11) to perform a battery cycle reset.
Take your e-waste to an R2 or e-Stewards certified recycler.

I just finished this repair. Note that when separating the back cover, you can go straight in for the top and bottom. The sides have curves in the glass. This requires angling your tool slightly up towards back cover to separate. Too much could scratch the back glass.
Also, between step 23 and #0024 there is a missing step. Before you heat and remove the vibrate component, you need to remove the circuit board for the charging port. There are 3 screws to remove using the #00 Phillips screwdriver. Also, disconnect the two ribbons. You can just disconnect the Main side to remove them with the circuit board.
Finally, I have yet to be able to find the Galaxy Cal APK
Hi Dave.
Thank you for the comment! I have added the missing steps. To find the Galaxy Cal APK, there's a link in the conclusion section labeled "Galaxy Cal App" that should give you the APK.
I really appreciate the response and the link. I downloaded and when I tried to run, after install, the app received the message "Try again after getting new version." The apk was Version 1.0.1-usa. Can you please advise? Thanks.
This requires an immense amount of patience and the persistent use of heat to disassemble this phone. I ended up breaking the front camera module while trying to pry it loose. Fortunately, this is available as a repair part and I was able to replace the front screen, camera, and battery and the phone now works perfectly.
