Introduction |
| Use this guide to replace a cracked or broken screen on your Samsung Galaxy S21 Plus. | | This guide was performed on the ***XXXXXXSM-G996B/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. |
