Title	Samsung Galaxy S21 Ultra Screen Replacement
Introduction	Use this guide to replace a cracked or broken screen on your Samsung Galaxy S21 Ultra. If the frame is deformed, it's important to replace it to make sure the new screen will mount correctly and won’t suffer damage from uneven pressure. If your battery is swollen, [[What to do with a swollen battery|take appropriate precautions|new_window=true]]. Before disassembling your device, ***discharge the battery below 25%***. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair. ***Note:*** This guide instructs you to replace only the screen while leaving the original frame and motherboard in place. However, some replacement screens for this phone come pre-installed in a new frame (a.k.a. chassis), which requires a very different procedure. Make sure you have the correct part before starting this guide. Although it’s not necessary to remove the interconnect cables to replace the screen we advise doing so. It makes the required motherboard removal and the reassembly way easier. Before you begin this procedure, be sure to have a set of replacement adhesives for both the rear glass and the screen.

Conclusion	If possible, turn on your device and test your repair before installing new adhesive and resealing. 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 these instructions in reverse order.*** The best way to secure the new screen is to apply a sheet of custom-cut double-sided tape to the back of the screen. Take your e-waste to an [[E-Waste|R2 or e-Stewards certified recycler|new_window=true]]. Repair didn’t go as planned?
