Use this guide to remove the rear glass of the Samsung Galaxy S9.

Opening the Samsung Galaxy S9 will damage the waterproof sealing on the device. If you do not replace the adhesive seals, your phone will function normally, but will loose its water-protection.

You’ll need replacement adhesive to reattach components when reassembling the device.

    • Before you begin, switch off your phone.

    • Apply a heated iOpener to a long edge of the phone to loosen the adhesive beneath the rear glass. Apply the iOpener for at least two minutes.

    • You might need to reheat and reapply the iOpener several times during the removal procedure to get the adhesive warm enough to cut. Follow the iOpener instructions to avoid overheating.

    • The adhesive of the Samsung Galaxy S9 is very strong. A hair dryer, heat gun, or hot plate may also be used if you aren't able to open the device with the iOpener. Be careful not to overheat the phone—the AMOLED display and internal battery are both susceptible to heat damage.

    Nightmare. Impossible to get the back off so far. Being trying using the iOpener with hair dryer for last 1hr. No chance.

    You’re right Chris. I’ve tried on 3 separate occasions now and haven’t been able to budge that back. All that has happened is the pick has taken a piece out of the glass back leaving a rough edge now.

    it was not easy but doable.

    It’s difficult, but the trick I did to get it was to wrap the hot iOpener around a bottom corner, apply the suction cup, then I covered the opener and phone with a paper plate, better insulating the area. Then I set my blow dryer to high heat and low velocity and heated the area under the plate for about a minute. Right after turning off the blower, I took off the plate and pulled the suction cup with a cutter at hand. You’ll hear a bit of a cracking/popping noise when the adhesive is starting to give, just apply a little more force and push the cutter at the seam. This method worked great for me, so good luck and just keep at it — you’ve got this!

    I used nearly boiling water in a storage zip bag on the phone for 10 minutes. I can’t really recommend this method, but thankfully the bag did not leak - an iOpener is probably a much better way to go. Regardless, the bag covered the entire back of the phone, and the phone was too hot to hold, but I still could not get the glass to budge with the suction cup after struggling with it for about an hour and multiple reheats. I ended up epoxying a 2”x2” square of PVC board to the bottom of the cover and built a relatively complex fixture that pulled on the PVC with the turn of a screw while it held down the frame by the edges. After heating the edges up again It did lift the glass enough to get a pick underneath it, but it cracked the glass and it was a pain to slide a pick around the edge while the glass was cracking all the way around. Once I finally got all the glass off, I spent the next 30 minutes (which is what this entire process is supposed to take… what a joke!) cleaning the adhesive off the phone.

    Heavy Duty Heat Gun from popular discount tool store for the win!

    Well, it is not obvious how to do this. I have no iOpener, but a heat cushion for remedy hurting muscles and sometimes a backpain. It is filled with grain of some kind and it is to be heated in a microwave oven for about 3 minutes. After that I enveloped this cushion round the phone and brewed myself a cup of tea. After ten miutes the phone was warm (almost hot) and I was able to press the tip of a small (very small) knife above the charging port into the connection between the phone body and the backplate. A very small opening emerged slowly (this is the critical point in this process) and I was able to start using the iFixit opening picks. It became obvious to me that the opening picks are too blunt to achive this with them. But after starting carefully with the (very small and very sharp) knife, everything went straight forward. Thou I had to give the phone a second heatpush with my heat cushion before the backplate came loose.

    • In the following steps, you'll be cutting through the adhesive securing the back cover.

    • The adhesive in the inside of the back cover is laid out as seen in the image.

    • You'll be slicing through the adhesive in the areas shown:

    • Thick portions of adhesive

    • Thin areas of adhesive

    • Avoid prying or slicing in this area, to protect the fingerprint sensor flex cable.

    • If the phone's rear glass is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.

    • Press a suction cup onto the back cover.

    • Lift the back cover's bottom edge with your suction cup, opening a slight gap between the back cover and the frame.

    • This may require a significant amount of force, but you only need to open a very slight gap with the suction cup to insert your tool. If you have trouble, apply more heat to further soften the adhesive, and try again. The adhesive cools very fast, so you may need to heat it repeatedly.

    • Insert an opening pick in the gap you created and slide it to the bottom right corner.

    • Insert a second opening pick and slide it to the bottom left corner.

    • Insert a third opening pick to prevent the adhesive from resealing during the rest of the removal procedure.

    The manufacturer obviously doesn't want owners to replace the battery, or they would have a simple method like they did in the past !!! They would rather have you throw it away and replace the phone !!!!

    • While inserting only the tip of the opening pick, slide it from the bottom left corner along the side to the top.

    • Slide the pick around the top corner and leave it there to prevent the adhesive from resealing.

    • Slide the opening pick from the bottom right corner along the side to the top.

    • Apply more heat if the adhesive becomes hard to cut. During the removal process, the back cover is under tension all the time and is likely to break if the adhesive isn't softened enough.

    • Slide the opening pick around the corner and cut the remaining adhesive at the top of the phone.

    • Don't open the phone all the way yet. The fragile fingerprint sensor cable still connects the back cover to the motherboard.

    • Carefully lift the side of the rear glass where the volume button is located.

    • Use the edge of a spudger to pry up and disconnect the fingerprint sensor flex cable.

    • Remove the rear glass.

    • When reassembling follow this guide to replace the adhesive and reinstall the rear glass.

    • In case you want to replace your rear glass follow this guide to transfer the rear camera bezel including the fingerprint.


Secure the new back cover with pre-cut adhesive or double-sided adhesive tape.

To reassemble your device, follow these instructions in reverse order.

After installing the rear cover, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond, such as by placing it under a stack of heavy books.

After you've completed the repair, follow this guide to test your repair.

Sollte nach Abschluss der Reparatur der Fingerabdrucksensor nicht funktionieren bitte folgende Schritte machen:

1. Schalte das Handy aus und hänge es ein Ladegerät

2. Starte das Handy im Restore Modus indem du die Bixby, Lauter und Powertaste gleichzeitig drückst bis das Samsung Logo kommt.

3. Wähle in dem Menü den Punkt: Wipe Cache Partition aus und bestätige mit Power deine Auswahl.

4. Starte das Gerät neu.
