Introduction
Follow this guide to replace the screen and battery assembly on your Samsung Galaxy S21+.
This guide is written for the 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.
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: Restoring water resistance after the repair will depend on how well you reapply the adhesive, but your device will lose its IP (Ingress Protection) rating.

The iFixit IOpener is way to thin for this job unless you work maybe a single side at a time. I ended up using a hair dryer. On my phone the power button side was the easiest side to start on. The suction cup didn't help me much. Do not push it, especially around the camera lens, I cracked my back cover because of impatience. Pretty simple operation once the back cover was off. The Samsung "kit" has extra stuff that's not really needed. Overall, excellent directions, Thanks Alex!!
The first time I did this was about a year ago and the whole set of instructions it was less than 1/2 the time and way easier. I also used a hair dryer but the first time was a bummer. this second time now it was pretty easy and split apart nicely. I think after you already did it once helped a lot. the instructions were precise. It helped me a lot by reading all the instructions a few times thru and the project went as nice as anyone could ask for. Thanks Alex !very nice job I'm 67 yrs old and it was a Breeze.
