Galaxy S21 Ultra Back Glass Cover Replacement for Samsung Galaxy S21U S21 Ultra 5G SM-G998B G998U G998U1 G998W Housing Door with Camera Glass Lens Parts and Pre-Install Tapes (Phantom Black)

Review: Great choice - It fit perfectly and was very easy to install. Total time for prep and install is around 15 minutes. It looks exactly the same as the original back cover. I've used it for months now without any issues with durability.
Review: OJBECTIVE, HONEST, & THOROUGH REVIEW - BEST OF THE WORST - I have fixed and flipped about 10 cellphones, so I know a little bit about the quality of replacement parts. I can tell you that this is an EXCELLENT back cover. I have seen some covers from AliExpress that are a lot worse than this. SAMSUNG LOGO ✓ This has the Samsung logo at the bottom. Some do not, which makes the back look empty and strange. PLASTIC, NOT GLASS ✓ Yes, this isn't glass, but that's a good thing. Don't ever get glass. Opt for plastic. You might think that it looks like the original, but glass simply is a bad material for a cellphone. If you install glass, it's likely you're going to break it. FLASH COVER ✓ This cover includes the lens cover for the flash camera. A LOT of cheap back replacements do not include the flash lens. SOLE CRITICISM The one major thing wrong with this cover is the color. There is a slight orange tint to the silver. Look at my picture. The phone on the right is an original cover. The left is this product. As you can see, under light, there is an orange tint. This seems like a major problem with all replacements. I guess manufacturers couldn't figure out the proper amount of tint to use. If you want a replacement that has almost no tint at all, you can buy this: https://www.desertcart.com/dp/B0D5YB7R7Z?th=1 But the lack of any tint made the cover look a bit flat. I didn't like it. SOME REPAIR ADVICE 1. Don't use glue. Use the sticker for the back cover. It's so much cleaner and easier. And it will make it easier for you if you need to take it off again. Otherwise, you'll have to spend hours picking at the glue. 2. Use a heat gun. It's easy to take off the back if you apply enough heat. A hair dryer simply isn't hot enough. If you're going to use a hair dryer, make sure you get the back hot enough. If you do, it makes removal easy. Just slide a plastic knife slightly underneath the edges and slice the adhesive.

## Questions & Answers

**Q: Can anyone confirm the small plastic housing from the flash also comes or do you need to remove it from the older cover? I only need the flash plastic**
A: Small plastic didn't come with a cover. You need to remove the old one and put in a new cover. Its a little messy and not easy to do.

**Q: Does it say Samsung on the back like the original?**
A: It does

### ⭐⭐⭐⭐⭐ Good fit. Use Youtube videos to understand disassembly and reassembly process before you begin.
*by T***D on October 16, 2023*

I found and watched a few Youtube videos on how to remove the back and then how to install a new one. I suggest watching a few of those if you are unfamiliar with the process. Be patient. Use heat carefully to soften the glue. I used a heat gun, sparingly. I found the included rubber bands insufficient to attain a tight enough seal for the glue to set. I cut two cell phone size pieces of cardboard from the box the new back came in. Placed those over the screen and back then wrapped the 3 rubber bands around them. I then used 5 small spring clamps around the edges to make sure it was clamped tightly together. I left it like that for about 2 hours. So far, it's only been a day, the back has remained nicely glued with no separation. Good replacement back glass at a good price that worked well on my S21 Ultra.
