Introduction

Use this guide to replace the back panel glass on the Samsung Galaxy S8 Plus.

If your replacement part does not come with adhesive mounted on it, you will also need to purchase adhesive for the rear glass and the fingerprint reader. You can buy pre-cut adhesive, or thin high-bond tape.

  • We recommend that you clean your microwave before proceeding, as any nasty gunk on the bottom may end up stuck to the iOpener.

  • Place the iOpener in the center of the microwave.

    • For carousel microwaves: Make sure the plate spins freely. If your iOpener gets stuck, it may overheat and burn.

which temperature must be used for heating? Thx

I found you need to be very patient when using the iOpener. It's worth taking your time, giving the heat time to work on the glue. When I finally got the battery out, there were some strips of glue left behind that I just cleaned off with some isopropanol before installing the new battery.

By the way, I had to run the iOpener for longer in my microwave for it to get hot enough. When it was too hot to touch, I figured it was hot enough for the batteries.

hello -

I didn't find this to be as hard as I had built it up in my mind to be; HOWEVER, saying that I need to say years ago I was the local Nokia service center in my town. But many years ago right after they got rid of analog times. Yeah. A classic installer/repairer mistake when starting something they haven't fixed or installed before is picking up the instructions, flipping through them; maybe even reading a section that is new-then tossing the instructions over the shoulder. "I got this." This usually comes right before something major gets broke. And I can tell you when you try to do it yourself and then mess it up horribly then take it to the repair shop. Well we called that "I can do it myself" syndrome and charged extra to put back together what they brought in in the box. Now knowing all this - I can't stress this enough because I am stupid, stupid, stupid. COVER YOUR SCREEN IN CLEAR BOXING TAPE AND READ ALL THE INSTRUCTION BELOW THROUGH TO THE END BEFORE EVEN ATTEMPTING THIS FIX. Take my advise.

I didn't have an iOpener, so I used a wheat type heat bag. If you do this though, make sure you put a layer of plastic between your Mac and the bag, or you'll get condensation in places you don't want it.

I started out using the iOpener but switched to my wife's hairdryer. A heat gun or hair dryer proved to be much more convenient and is a time saviour. You can heat more and the glue becomes more fluid make the next steps with the opening picks much easier

Use a hair dryer! Watch this vid: https://youtu.be/16GkvjVyOJA It is much easier to do if you heat it from the other side.

I wonder how many people actually wrapped in their iPhone into iOpener and put this "sandwich" into microwave??

I know this is obvious, but backup your iPad with iTunes before you start. I'd also turn off your passcode if you have one.

  • Heat the iOpener for thirty seconds.

  • Throughout the repair procedure, as the iOpener cools, reheat it in the microwave for an additional thirty seconds at a time.

  • Be careful not to overheat the iOpener during the repair. Overheating may cause the iOpener to burst.

  • Never touch the iOpener if it appears swollen.

  • If the iOpener is still too hot in the middle to touch, continue using it while waiting for it to cool down some more before reheating. A properly heated iOpener should stay warm for up to 10 minutes.

May I know the temperate limit about heating iOpener? (maximum 150 degrees Celsius?) thx so much.

I had to heat mine up for more than 30 seconds. After 30 seconds on high it was only warm. It had to keep trying different times and checking it until it got hot. I think the initial time that I put it in for was over a minute.

DO NOT USE IN NON ROTATING MICROWAVE! It will pop a hole. I had it in for 45 seconds the first time. It wasn't very hot inside and I saw it started to leak on the paper towel I put under it. Just a fair bit of advice. I think I will just stick with the heat gun. Loud but useful.

If I don't have a microwave then I try to use hot air gun so how many munuts i want to heat ?

I heated mine up for 30 seconds, tested, then again for 30 seconds. It felt adequately hot. Leaving it on the left side, per the instruction, for a minute did not loosen the adhesive. I ended up pulling the suction cup hard enough to shadder the old screen. Moral of the story, I don't think it gets hot enough safely to have an affect.

  • Remove the iOpener from the microwave, holding it by one of the two flat ends to avoid the hot center.

Image 1/2: The adhesive on the rear case is laid out as seen in the first image. Image 2/2: The prying pattern as seen from the outside of the phone is as follows:
  • In the following steps you will be cutting through the adhesive around the edge of the rear glass panel.

  • The adhesive on the rear case is laid out as seen in the first image.

  • The prying pattern as seen from the outside of the phone is as follows:

    • Thick portions of adhesive

    • Thin areas of adhesive

    • Avoid prying here, to protect the fingerprint sensor.

Image 1/1: The suction cup will not make a good seal on the curved portion of the glass, so avoid putting it on the very edge.
  • Once the back panel is warm to the touch, apply a suction cup as close to the heated edge of the phone as you can.

    • The suction cup will not make a good seal on the curved portion of the glass, so avoid putting it on the very edge.

  • Lift on the suction cup, and insert a Halberd spudger or opening pick under the rear glass.

    • Due to the curved glass, you will be pushing up, rather than inserting parallel to the plane of the phone.

  • Once you have the tool firmly inserted into the glass, reapply the iOpener to soften the adhesive, reheating it if needed.

Image 1/2: As you lift the glass, peek in to be sure the orange cable with a blue connector has disconnected. Image 2/2: Use the opening picks to slice through any remaining adhesive and open the phone slightly.
  • The fingerprint sensor cable connects the phone to the rear glass near the main camera. The cable is very short and should disconnect as the rear glass is removed.

  • As you lift the glass, peek in to be sure the orange cable with a blue connector has disconnected.

  • Use the opening picks to slice through any remaining adhesive and open the phone slightly.

  • If the fingerprint sensor cable seems snagged or stays taut do not open the phone any further. Use the tip of a spudger to lift the connector and disconnect the sensor cable before proceeding.

  • Remove the glass from the phone.

Image 1/2: Reheat an iOpener and apply it to the fingerprint sensor mounted to the rear glass. Image 2/2: Push the fingerprint sensor off of its adhesive from the outside of the glass.
  • If you're reusing the rear glass panel, skip this step and leave the fingerprint sensor on the panel. If you're replacing a damaged rear glass panel, you will have to transfer the fingerprint sensor to your new rear glass panel as follows:

    • Reheat an iOpener and apply it to the fingerprint sensor mounted to the rear glass.

    • Push the fingerprint sensor off of its adhesive from the outside of the glass.

  • If you have trouble pushing the fingerprint sensor out, slide a Halberd spudger along the edge of the sensor to cut some of the adhesive. This will make the adhesive less likely to be reusable, however.

Image 1/1: If you're reusing the original rear glass panel, you will need to remove the old adhesive from the rear glass panel and clean it with high concentration isopropyl alcohol. After the panel is clean, apply the new adhesive.
  • Before replacing the rear glass, remove any remaining adhesive and clean the edges of the phone body with high concentration isopropyl alcohol (at least 90%).

  • If you're reusing the original rear glass panel, you will need to remove the old adhesive from the rear glass panel and clean it with high concentration isopropyl alcohol. After the panel is clean, apply the new adhesive.

  • If you're installing a new rear glass panel, make sure you compare the old rear glass panel to the new rear glass panel and transfer any missing components to the new rear glass panel.
