Use this guide to replace a cracked or broken screen on your Samsung Galaxy S21 Ultra.

This guide was performed on the ***SM-G998B/DS*** (international) model. Other models have an additional antenna cable sitting in the edge of the midframe.

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.

If you do not replace the adhesive seals when reassembling, your device will function normally, but will most likely lose its water protection.

Before you begin this procedure, be sure to have a set of replacement adhesives for both the rear glass and the screen.
