Samsung Galaxy S9 – Teardown / Screen replacement (with frame)

Samsung Galaxy S9 – Teardown / Screen replacement (with frame)


Hi, I’m Emal from iDoc
If you dropped your Samsung Galaxy S9 and cracked the screen, this video shows you how
to replace it yourself. To fix the phone, we replace the whole display unit. The repair is a bit more difficult, because
the back cover glue is pretty strong. You need about 60 to 90 minutes. We recommend the following tools:
Several flat picks, a wide, thin opening tool, a Phillips screwdriver, a suction cup,
a steel spatula, ESD tweezers and a plastic spudger. The opening tool should be as wide and then as possible, like the iFlex or iPlastix. You need a heat gun or hair dryer to soften
the glue. At our store iDoc.eu, you’ll find the spare part and
the most important tools in our repair kit – including our nifty magnetic pad. Our website idoc. eu shows detailed photos
and videos for each step. And now, enjoy this fix. Before you start, you should have all your tools ready. Also work on a clean surface to prevent dirt from entering and scratching the device. Switch off the device first to avoid short
circuits. Press and hold the power button until the
Power off option appears. To loosen the back cover, use a heat gun or
an ordinary hair dryer. Warm glue is easier to loosen, allowing you
to remove the back cover. The easiest way to loosen the back cover is
to use a flat and flexible tool such as the iPlastix or iFlex. You will also need several picks to unstick
the back cover all around. Heat the spot where you start and place a
suction cup on the bottom of the back cover. Press a flat tool between the back cover and
the frame and pull on the suction cup. The iPlastix is made of plastic, so it won’t
scratch the frame. On the other hand, it’s very soft and tricky
to insert. If necessary, apply the heat several times
and try again. Be extra careful, the back cover can break very easily. Removing the back cover might take half an
hour. You better take a little more time and work
carefully to make sure you don’t break anything. Once the tool is inserted, stick a pick into
the gap to keep it open. Then run the tool around the entire edge to
gradually loosen the glue. You can already take off the suction cup. Then heat the next part and insert the picks
one by one. The back cover glue is extra strong on the
lower edge. Once the back cover is loosened, lift it very
slightly. The fingerprint sensor underneath the camera
is still connected with a cable. Unplug the connector with a narrow spudger. Here at the edges you can see the glue. The back cover glue is extra wide just over
the USB connector. Now take off the back cover and put it aside. Then remove all the equally long Phillips
screws from the logic board cover and store them together. This phone has only 2 different screw lengths. If some screws don’t come off immediately,
you can also use a pair of tweezers. The logic board cover with the NFC tag is
latched in at the top. Pry it up a little and then take it out. Now the battery connector is free. To avoid short circuits during the repair,
disconnect the battery. In the next step, remove the speaker. These screws are also equally long. Lift the speaker a little using tweezers and
then remove it. Now disconnect the front camera connector
using a spudger. Pry it up from the free side where there are
no PCB components. Then take the camera out of its holder. Now remove the SIM tray. The best way is to use a SIM tool or a paper clip. Then pull out the SIM tray. Now disconnect the different plugs from the
logic board. Twist the spudger gently. Don’t use it like a crowbar, or you may damage
the logic board. There are small parts next to the connectors that break easily. Then disconnect the button plugs of the antenna cables. Grab the cable with the tweezers, not on the plug itself. Disconnect the plug with a twist of the tweezers. Now remove the single screw on the logic board. Before removing the logic board, make sure that all connectors are bent aside and don’t get stuck. The bottom side of the logic board is still
connected to the USB board. Fold up the logic board and flick off the
connector using a spudger. Then put the logic board aside. Use tweezers to loosen the glued on sensor cable unit. The cable unit is latched in at the top. Lift it up a little and unglue the copper
tape. Use a flat tool to unglue the earpiece – if
necessary. If your spare part comes with a new earpiece, you don’t have to reuse the old earpiece. Then remove the vibration motor, which is
also glued. Pry out the motor gently using a flat tool. Next remove the audio jack. It’s fastened with a screw. Loosen the screw and then unplug the connector. There’s a recess in the upper corner, where you can pry out the audio port. Then remove the other screws of the USB board. They’re all the same length. The cable of the USB board is glued to the
frame. Use a spatula to unglue it. Then pick up the USB board and gradually release it using the spatula. Now take out the whole USB board. As a last step, remove the battery. The battery glue is very strong, so you should use hot air again. Never heat the battery directly. Apply the hot air from the display side. We recommend running a flat tool, such as the iFlex, all around the battery. Be careful not to damage the battery and neighboring parts. Take your time and heat the glue several times. Now take out the battery. As you can see, the battery only has glue
around the outer edges and not at the center. You can get the matching spare part and tools
at idoc.eu Now take the new display and compare it to
the old one. If necessary, you have to reuse some gaskets
or holders. Remove the backing films from the sticker
surfaces, so you can attach the front camera or sensors, for example. Now insert the battery into the display unit
and press on the glue. Then take the USB board, place it in the case and press it in. Make sure that all parts are correctly seated. Stick the flex cable back to the frame. Now put the antennas in their holder. Start with the blue antenna. Fasten the USB board’s screws now. Reinsert the audio jack and press it in. Attach the connector and fasten the screw. Then insert the vibration motor and press it in. Then put the earpiece back in. Now insert the sensors into their holder and press them down. Make sure they are sitting properly. Take the logic board and plug in the connector at the bottom. Now slowly fold the logic board into the
device. Make sure you don’t squeeze in any cables. Bend all antennas and connectors to the side. Press the logic board in to make it click
into place. Then attach the single screw to the logic
board. Now attach all the plugs. You can position the antenna plugs with tweezers
and then click them on. Also attach the connectors for the display
and the volume buttons. All connectors engage with a click. If not, remove the connector and try again. Now insert the SIM tray. If it gets stuck, the logic board may not
be sitting right. Insert the front camera and attach its connector. Then place the speaker back over the USB board,
press it in and screw it tight. Make sure it’s latched in at the bottom. Now connect the battery again. Then attach the logic board cover with the
NFC tag. Latch it in and press it in all around. Then fasten all the screws again. Before reattaching the back cover, check the
glue. It should be sitting evenly on the back cover. You can remove any excess glue. Before attaching the back cover, plug in the
fingerprint sensor connector. Use a plastic tool to reach the connector. Then test your display. Turn on the device and open the dialpad. Enter star, hash, zero, star, hash to open
the test menu. The test menu lets you check the display for
pixel errors and test the touch screen. Also check all other functions such as the
camera, speaker, or status LED. If everything works, you can attach the back
cover permanently. Heat the back cover again to bond the glue. You can press on the back cover with your
fingers while the glue cools down. Please note that your smartphone’s water ingress
protection is no longer the same after you open it. Your device is fixed now, and I hope you enjoyed
it. You can find tools and spare parts at our

  1. I incorrectly inserted the sim ejector pin to the mic hole near the USB Type C connector.. Will it damage the waterproofing of my S9?

  2. Its not a piece of cake when the LCD screen and back glass is broken. Very tough to remove all glass from the phone and sometimes frame can be bend too. BTW its a nice video. Thanks.

  3. I have never ever had a crack in a cellphone before, I even had a s6 edge for over 2 years. Now after 1 month the screen of my brandnew s9 is allready cracked; I didnt even drop the phone but had it in a plastic bag and just layed it on the ground and it cracked…

  4. Hi iDoc, I was recently applying a uv screen guard and glue went into the front speaker and blocked it, I took a needle and pierced it lil hard and now there is a lil hole on the grill, Does that mean I should replace the whole screen to get rid of it ? And did that hole took out the water resistence? The hole is around half millimeter wide.

  5. The only detailed video i've found on youtube i shall be using this video to repair my s9 black screen coral blue frame and black back glass should look cool

  6. I have only the front glass of my samsung s9 plus that is broken.Can you please tell me if i can install new glass without pulling the whole thing apart?.Thanks in advance.

  7. No thanks lol ill leave it to the experts. I'll pay for the extended warranty. My LCD screen and camera component was just replaced at Samsung on my 2 month old Samsung s9 plus. It was nothing I did. It was bought that way but I refuse to switch to iOS because they are such boring phones. Samsung has extremely beautiful cameras when they work correctly.

  8. cracked my s9 cracked it on the edge on the screen, dropped it, didnt realize how expensive it is to replace screen, heard bank insuarce claim is cheapest way to go round it

  9. I just did this and the only difference in teardown with this and the S9+ is the blue & white cables are flip flopped and there are two screws that hold down the motherboard. Just a heads up…the rest is the same. 😉

  10. How can I know if I need the frame to replace my screen. what exactly is the frame and is it needed to replace my s9 screen

  11. Do you have any tricks for turning offa galaxy s9 with a damaged flickering screen when the power off button will not work. I dropped it and it has a very damaged screen and display, because of the constant flickering it's very hot and I can't turn off! 🙁

  12. What about the side housing around the edge of the phone can you replace that.. dropped mine and dented it, I think it's some sort of steel
