Galaxy S20: Back Glass Replacement Guide
Hey guys! Today, we're diving deep into how to replace the back glass on a Samsung Galaxy S20. Cracking the back of your phone is a bummer, but don't worry, you don't necessarily have to rush to a professional. If you're a bit handy and patient, you can totally tackle this yourself. I’m going to walk you through the process step-by-step, making it super easy to follow along. So, let’s get started and bring that beautiful Galaxy S20 back to its former glory!
What You'll Need
Before we get our hands dirty, let's gather all the tools and materials you'll need. Trust me, having everything prepped and ready will make the whole process smoother and faster. First off, you'll need a replacement back glass specifically designed for the Samsung Galaxy S20. Make sure it matches the color and finish of your phone to keep that sleek look.
Next, grab a heat gun or a hairdryer. This is crucial for softening the adhesive that holds the back glass in place. Be cautious and use a low setting to avoid overheating any components. You'll also need some precision opening tools, like thin plastic pry tools or guitar picks. These will help you gently lift the glass without causing further damage to the frame or internal parts. A suction cup can be handy for getting that initial grip on the broken glass, giving you something to pull on as you start prying.
Don't forget a Phillips head screwdriver for removing any internal screws that might be holding down components near the back glass. You’ll also want some adhesive remover, such as isopropyl alcohol (90% or higher), to help dissolve the old adhesive. A clean microfiber cloth is essential for wiping away any residue and ensuring a clean surface for the new adhesive.
Finally, you'll need new adhesive strips or glue to secure the replacement back glass. Pre-cut adhesive strips are super convenient, but you can also use B-7000 glue if you're comfortable applying it evenly. With all these tools and materials at your disposal, you're well-equipped to tackle this repair like a pro! Remember, preparation is key, so double-check you have everything before moving on to the next step.
Step-by-Step Guide
Alright, let's get into the nitty-gritty of replacing that back glass. Follow these steps carefully, and you'll be rocking a flawless Galaxy S20 in no time!
Step 1: Heat It Up
First, you need to soften the adhesive holding the back glass. Grab your heat gun or hairdryer and set it to a low setting. Gently apply heat around the edges of the back glass for about two to three minutes. Move the heat gun in a circular motion to avoid concentrating heat in one spot, which could damage the internal components. The goal here is to make the adhesive pliable, not to cook the phone! Once the edges are warm to the touch, you're ready to move on.
Step 2: Create an Opening
Now it’s time to create a small gap between the back glass and the frame. Attach a suction cup to the lower edge of the back glass, near the charging port. Gently pull up on the suction cup while inserting a thin pry tool or guitar pick into the gap you’ve created. Be super careful not to force anything; if it’s not budging, apply a bit more heat. Once you’ve got a small opening, remove the suction cup and insert a second pry tool to keep the gap open. This prevents the adhesive from re-sealing as you work your way around the edges.
Step 3: Loosen the Adhesive
With your pry tools in place, slowly slide them along the edges of the back glass to loosen the adhesive. Use a back-and-forth sawing motion to help separate the glue. Remember to be patient and apply more heat if you encounter resistance. Work your way around the entire perimeter of the phone, ensuring you’ve loosened all the adhesive. Pay special attention to the corners, as they tend to be the trickiest spots. Take your time and don’t rush – a little patience here will save you from potential headaches later on.
Step 4: Remove the Back Glass
Once you’ve loosened all the adhesive, carefully lift the back glass. If it’s still sticking in some areas, double-check that you’ve thoroughly heated and pried around the edges. Lift the glass slowly and evenly to avoid bending or breaking it further. With the back glass removed, you'll likely see some residual adhesive on both the frame and the back of the glass. Don't worry, we'll clean that up in the next step.
Step 5: Clean Up the Residue
Now for the not-so-fun part: cleaning up the old adhesive. Grab your adhesive remover (isopropyl alcohol works great) and a microfiber cloth. Dampen the cloth with the adhesive remover and gently wipe away any remaining adhesive from the frame and the old back glass. You might need to apply a bit of pressure and use a scrubbing motion to remove stubborn pieces. Be careful not to let the adhesive remover seep into any openings or ports. A clean surface is crucial for ensuring a strong bond with the new adhesive, so take your time and get it as clean as possible.
Step 6: Apply New Adhesive
With the surfaces clean and dry, it’s time to apply the new adhesive. If you’re using pre-cut adhesive strips, carefully peel them off the backing and apply them to the edges of the phone frame. Make sure the strips are aligned correctly and press them firmly into place. If you’re using B-7000 glue, apply a thin, even bead around the perimeter of the frame. Avoid applying too much glue, as it can squeeze out and make a mess. A little goes a long way here. Whether you're using adhesive strips or glue, make sure you create a continuous, unbroken seal around the entire frame.
Step 7: Install the New Back Glass
Carefully align the new back glass with the phone frame. Take your time to ensure it’s perfectly aligned before pressing it into place. Once you're satisfied with the alignment, gently press down on the back glass, applying even pressure across the entire surface. This will ensure a strong bond between the adhesive and the glass. If you’re using adhesive strips, you can apply some heat to further activate the adhesive. A few minutes under a warm heat gun or hairdryer will do the trick. After applying pressure and heat, let the adhesive cure for at least 30 minutes to ensure a secure bond.
