Introduction

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

Before disassembling your phone, discharge the battery below 25%. If your battery is swollen, do not heat your phone. Swollen batteries can be very dangerous, so wear eye protection and exercise due caution, or take it to a professional if you’re not sure how to proceed.

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

What you need

Step 1

              Rear Glass Removal
  • 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.

Step 2

  • 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.

Step 3

  • 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.

Step 4

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

Step 5

  • 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.

Step 13

              Battery
  • Use an iOpener to loosen the adhesive beneath the battery. Apply the iOpener for at least two minutes.
  • In the following step, only apply the spudger in the areas marked in green, which is where the battery adhesive is located.
  • Avoid this area. There’s a gap in the mid-frame right below the battery, and you can accidentally damage the display through it.

Step 14

  • In case you have trouble to pry up the battery the adhesive may not be loose enough. You can apply some isopropyl alcohol under each corner of the battery and allow it to penetrate for several minutes to help weaken the adhesive.
  • Try your best not to deform the battery during the following removal process. Soft-shell lithium-ion batteries can leak dangerous chemicals, catch fire, or even explode if damaged. Do not use excessive force or pry at the battery with metal tools.
  • Insert the flat end of a spudger at the top left corner of the battery where the flex cable is located and start to pry it up.
  • Work your way down the left side of the battery and loosen the adhesive with the spudger.

Merci ifixit.

Mais je n ais pas compris la deconnection du NFC, es une nappe. Je ne comprends pas.

Sandra Hiller - Apr 22, 2020

Bonjour @Di Da, vous trouverez la partie qui parle de la démontage du coque / de la cache en plastique qui abrite l’antenne NFC et la bobine de recharge dans les étapes 9 à 11. Au fait, la cache en plastique et la nappe sont UNE pièce ensemble, on ne peut pas les séparer et dès que vous démontez la cache, la nappe va elle aussi sortir automatiquement. Elle n’est lié que par quelques contacts, vous n’avez pas besoin de déconnecter ceux-ci, ils se séparent automatiquement quand vous retirez la coque.

Wenn nach Abschluss der Reparatur der Fingerabdrucksensor nicht funktioniert muss man in den Restore Modus des Handy gehen.

Dazu das Smartphone an den Lader hängen und das Gerät ausschalten.

Dannach die Bixby + Power + Lauter Taste gedrückt halten bis das Samsung Logo erscheint.

In dem Menü den Punkt “Wipe Cache Partition” auswählen mit Lauter / Leiser und mit Power die Auswahl bestätigen.

Die Auswahl nochmal mit Yes bestätigen und warten bis das Gerät die Cache Partition gelöscht hat und das Gerät neu starten.

Dannach sollte der Fingerabdrucksensor wie gewohnt funktionieren.
