Use this guide to replace the rear camera 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.
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.
You’ll need replacement adhesive to reattach components when reassembling the device.

does 3x camera can be seperated too?
Hi Watcher,
you can detach the telephoto camera from the assembly easily including its frame. It is only held to the assembly by a small metal pin. However separating the cameras from their frame is very difficult. The frame sits very tight around them and in case of the ultra-wide and wide cameras you risk damaging both when trying to remove one.
Dominik, your repair guide is excellent. Thank you. Can you or ifixit recommend a reputible source for the camera components for the S21 Ultra? I read of bad experiences with parts sourced through ebay, and ifixit doesn't offer the needed parts for sale on their site. I wish they would!
hey, can you please tell me where I can buy these cameras?
unfortunately I was taking a video of a stone blast which shattered all three camera glasses and the lenses were damaged too. even though all three cameras are working but the pictures come out blur, so I need to purchase the whole set of cameras so I can replace them with the old ones.
Im from Pakistan!!
The telephoto camera has a real mechanical assembly that moves a physical lens according to the zoom setting, up to 100x. I took a picture of the August 2023 Blue Supermoon with it. The image on the screen is about 2.5 inches or 63 mm in diameter. This is excellent for a smartphone with no added lenses.
