Get ready to rock n’ roll with this fun guide to replace the fingerprint sensor on your Samsung Galaxy S8! Don’t worry, it’s a breeze. Just prepare that dating-night outfit as you’ll be getting down and dirty with the phone’s back cover removal. No worries though, we’ll have you back in action in no time! If you’re still doubting your superhero repair skills, you can always schedule a repair.
Step 1
Make sure to give your microwave a quick clean-up before diving in. Any leftover gunk on the bottom might just cling to the iOpener, and nobody wants that mess!
– Now it’s time to heat things up – literally. Place the iOpener in the microwave, right in the center, and get ready for the next step. If you need help, you can always schedule a repair

Step 2
– Get your iOpener ready by heating it up for 30 seconds.
– As you work through the repair, remember to reheat your iOpener in the microwave for an extra 30 seconds whenever it starts to cool down. And don’t worry if you need a hand – you can always schedule a repair with Salvation Repair.
Heads up, iOpener pals! Make sure you don’t toast this bad boy because it might go BOOM if it gets too hot. Keep that temps under 100˚C (212˚F), k? And no snuggles with the iOpener if it looks like a stuffed sausage. If it’s too toasty, take a break and give it some space. A well-warmed iOpener should chill out for about 10 minutes – just like us when we’ve had a tough day. If you need help, you can always schedule a repair!

Step 3
Caution: The iOpener is going to be pretty toasty! Handle it with care, and don’t hesitate to grab an oven mitt if you need a little extra protection.
– Carefully take the iOpener out of the microwave, grabbing it by one of the flat ends to steer clear of that hot center. Safety first, right?

Step 4
No microwave? No problem! Just pop your iOpener into some boiling water to warm it up.
– Grab a pot or pan and fill it up with enough water to give your iOpener a nice, cozy bath.
– Turn up the heat and bring that water to a rolling boil. Once it’s bubbling away, go ahead and turn off the heat.
– Carefully drop your iOpener into the hot water and let it soak for 2-3 minutes. Just make sure it’s completely submerged; it deserves a good dip!
– Using some tongs (safety first, right?), fish out the heated iOpener from the water.
– Give the iOpener a thorough drying with a towel. We want it nice and dry for its next adventure!
– And there you have it—your iOpener is now ready for action! If it needs a little more warmth later, just repeat the steps: heat the water to a boil, switch off the heat, and let it relax in the water for another 2-3 minutes.

Step 5
Hey there! If you want to get creative, you can also try using a hair dryer, heat gun, or hot plate. Just remember to keep it cool – both the OLED display and internal battery are a little sensitive to heat. So be gentle with the heat!
Yikes, opening your phone means saying goodbye to those sweet waterproof seals. Don’t forget to have that adhesive ready or be extra careful with any H2O exposure. Ready for the next step? Let’s go!
– Warm up an iOpener and place it on one of the longer edges of the S8 for around 2 minutes.

Step 6
– Let’s dive into the fun part! First up, we’ll be carefully slicing through the sticky adhesive that hugs the edges of the rear glass panel.
– Take a peek at the first image to see how the adhesive is arranged on the rear case—it’s got a bit of a pattern going on!
– Check out the prying guide from the outside of the phone; here’s how it goes:
Step 7
– Warm up that back panel until it feels like a cozy hug, then stick a suction cup near the hot spot of the device while steering clear of the curvy bits.
– Give that suction cup a gentle lift and slide an opening pick beneath the back glass with a touch of finesse.
Step 9
Take it easy and keep the tool snug in the gap. If the cut is giving you trouble, just give the iOpener another warm welcome and try again!
– Now it’s time to get this phone opened up – slide the opening pick down the side, gently breaking the adhesive seal. If you need help, you can always schedule a repair

Step 10
– Now, let’s keep that momentum going! Just like before, heat things up and slice away on the next three sides of your phone.
– Don’t forget to tuck an opening pick into each side as you go along to keep the adhesive from sticking back together. You’ve got this!
Step 11
As you gently raise the glass, take a quick peek inside to ensure that cheeky orange cable with the blue connector is free and clear. No one likes a tangled mess!
If the fingerprint sensor cable appears to be stuck or feels like it’s on a tightrope, hold up! Don’t push the phone open any further. Use the tip of a spudger to carefully disconnect the connector before you dive deeper.
The fingerprint sensor cable is like a tiny bridge connecting your phone to the rear glass near the main camera. It’s a bit on the short side, so when you gently lift off the rear glass, it should easily disconnect. No worries, it’s all part of the process!
– Grab those opening picks and gently slice through any leftover adhesive to get the phone open just a tad.
– When it’s time to put everything back together, tilt the back cover into place so the fingerprint sensor cable aligns perfectly with its connector. Then, take the flat end of your spudger and give that connector a gentle press straight down to snap it in securely.
– Carefully remove the glass from the phone.
Step 12
Feelin’ groovey? If you’re up for it, you can totally reinstall that back cover without breakin’ out the sticky stuff. Just sayonara to any big globs of adhesive holdin’ you back. After it’s all said and done, pop it in the sun and give it some lovin’ to keep everything stickin’ together. Ain’t waterproof, but the glue’s got your back in a pinch!
– Alright, time to jazz things up with a new back cover:
– Just follow this easy-peasy guide to pop on that old back cover like a breeze, or stick on a fresh one with no adhesive.
– You might also have to shift the camera bezel over to your new part. If that’s the case, check out our cool camera bezel replacement guide.
Step 13
– Got a new rear glass panel? Awesome! Just don’t forget to move the fingerprint sensor over to your shiny new panel like this:
– If that sensor is being a bit clingy, no worries! Just slide an opening pick gently under the plastic backing to help loosen the adhesive before giving it a little push.
Step 14
– After removing that old sticky stuff, give those fingerprint sensor edges a good cleaning with some strong alcohol (90% or more). Then, slap on some fresh adhesive and you’ll be good to go! If you need help, you can always schedule a repair.
If the fingerprint sensor’s sticky friend is still hanging on, you can give it a second chance! If it’s given up the ghost, don’t worry – just stick on some pre-cut adhesive buddy and you’re good to go. Need a hand? No sweat, you can always schedule a repair to get those touchy feely tech troubles sorted!
