Introduction

Use this guide to replace a cracked or broken screen on your Samsung Galaxy S8.

This guide involves removing the rear glass cover, you will need replacement adhesive to reattach the back cover to the phone. If your replacement screen does not come with adhesive, you will need to use tape to secure it as well.

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.

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.

Ther first time you heat up the iOpener for this repair when its room temperature I had to heat it up for more than 30 seconds. I remember I had to heat it up for around 45 seconds. However, after that when you need to reheat it again during the repair 30 seconds will be enough.

I've been with Samsung for 8 years now!! Never did i have a case on any of my phones My Samsung 8 is 2 months old the case protector around the edge pop off and broke my phone it's like someone put a bullet hole in it

Heat the iOpener for thirty seconds.
  • 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.

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.

Travis Dixon - Reply

There is a clear problem here with the heating part using the iopener things....no details are given. Whoever is testing them needs to make it clear - What temperature does it need to be? And for which phone models, because they differ in what's needed. It's only £10-15 for a laser guided temp sensor unit, and the designers/repairers should have one of those already for doing these kinds of repairs. Explaining half a repair, is worse than not explaining at all :-(

I used a hot water bottle, works well as it covers the whole screen and stays hot for longer.

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

Slide the blade of a Halberd spudger down the side of the phone, separating the adhesive. Go slowly so that the tip doesn't slip out of the seam. If cutting becomes difficult, reheat and reapply the iOpener.

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.

Did my first repair two days ago. If you've done any other samsung repairs such as S7 or S7E, this will be cake for you to do. If you have big fingers like I do, the most challenging thing will be the fingerprint scanner flex on the back glass, connecting and reconnecting.

I go about this repair a bit differently if I want to salvage the lcd. I remove the battery motherboard and sensors , and start through the opening in the frame under the battery. I drip isopropyl alcohol along the perimeter of the battery opening applying heat and work a playing card in between the LCD and the frame, loosening adhesive as I go.

I like the way you think.

Jason Stewart -

Great guide, very accurate. Be very careful along the right side of the device, as it is very, very easy to shear the connector flex in half. To avoid any chance of damage, I remove the board and front camera/sensor flex. It's an easy job, and saves a massive headache if any parts are damaged. Overall quite a familiar phone to work on, if you've ever done any S6's and upwards.

Jonathan Ruiz - Reply

Hi Jonathan! This guide is to replace the whole screen assembly. The OLED screen is extremely thin and fragile and cannot be removed safely from the glass by the ordinary DIYer, to say nothing of the reassembly process. It makes it a bit more expensive to have a fused display but this repair isn’t possible with separated display/glass components.
