A cracked display is no fun. I know you’re
thinking you have to live with it, but I’m here to tell you you don’t. And today
I’m going to show you how to replace the display in your Galaxy S7. For this
repair you’re going to need a heat gun, a Philips #00 screwdriver, an iSclack
or a suction cup, opening picks, a spudger and a scraping card. just a
warning opening your Galaxy S7 may reduce the
water resistance capabilities of this device. Before we begin understand this
repair is on the difficult side due to all the adhesive. Take caution and be
patient as it’s easy to break components that are adhered. as always
make sure that the phone is completely turned off once you’ve turned off the
phone we’re going to try to remove the back panel start by taking out the SIM
card at the top of the phone. The S7 is unfortunately held together with
adhesive so you’ll need to heat and loosen the glue on the back before
moving on we are using a heat gun for this device please take caution not to
overheat your device. Do this by staying in the lowest power and not getting too
close. Heat up all sides of the phone Then use your iSclack or suction cup to lift up one edge of the panel just enough to
insert an opening pick. This pick will ensure that the glue does not reset as
it cools. Now use an additional pick to cut the adhesive up the left side and
another one for the right. If you run into a lot of resistance, just use more
heat before cutting with the picks. Once everything is cut you should be
able to lift the back panel from the phone. Time to remove the 12 Phillips
screws holding the antenna module, the NFC module, and the speakers in place.
Once the screws are removed lift the modules out of the phone. It’s important to note that you should disconnect the battery as soon as the connector is
accessible no matter what component you’re going to replace. Now we can see
the battery. To remove the battery we’ll need to pry a bit of adhesive to get it
out of the phone. You can use a spudger, but I found these pics work quite nice. Moving on to the motherboard—
disconnect all the cables holding the motherboard down, including the two small
antennas on the left side. With everything disconnected you should be
able to lift the motherboard carefully from the top of the phone. Do not remove
the motherboard completely, as there’s a cable connected to the underside of the
board. Disconnect that and remove the board from the phone. On to the display! We
recommend not doing this repair unless the screen is already broken. There is
adhesive around the entire perimeter of the display. Start by heating the side
with the volume buttons with your heat gun. And just like before, take caution
when using your heat gun. You don’t want to overheat any components on the inside. Once it’s nice and warm, take your pick
in between the mid frame and the display. If you run into resistance, hit it with
more heat. Leave one pick in to keep the glue from resetting. Cut the glue on the
edge but don’t round the corner just yet. Then add a card under the mid frame on
the opposite side just like you did with the first pick. With the card in place,
insert another pick and cut the adhesive on the right side. With both long edges released, attempt the top corners. When you move to the bottom two corners, take caution. There’s some delicate cables at the bottom you don’t want to cut. Now you
should be able to lift the display from the phone. You can find all the parts and
