简介
Follow this guide to replace the screen and battery assembly on your Samsung Galaxy S21 Ultra.
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: 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.

How do we seal the back cover after replacing the screen? iFixit toolset does not come with glue or adhesive. It is not clear if the screen replacement part already has adhesive on it.
Save yourself a lot of hassle and don't separate the camera lens assy from the back cover. Then during reassembly withr pre-cut adhesive, cut that section away at the small lines indicated on the adhesive.
The back cover is glass... not plastic, so be careful..... use regular intervals of heat applications. Apply 10x the heat it says....
because the glue is strong. The older the phone the more stubborn the adhesive. Worse case scenario you might need to by the back cover.
We cracked ours a little but was reusable....
My screen replacement kit came with an adhesive cutout labeled as "G998 TAPE 3RD MIC HOLD TAPE". After much searching I was unable to find anywhere in these instructions or on the phone where it discussed using this adhesive. I am unsure where in the phone the adhesive goes. Clarification would be appreciated. I suspect it may go under the camera assembly but in these instructions that is removed whole with the motherboard so it may be an unnecessary item.
Thanks for the guide on how to replace the screen. My wife's S21 Ultra is working great and I look like the hero. My only suggestion is to add an how to add the Samsung adhesive strips and where they go. @john84651 Thanks for the tip on removing the adhesive from the antennas.
