Replace Your Samsung Galaxy A70 Screen In 10 Steps

Replace Your Samsung Galaxy A70 Screen In 10 Steps

Replace the screen on your Galaxy A70 if it is cracked or broken with this guide.There are several factors to consider when dealing with a deformed frame. It is important to replace the frame in order to ensure the new screen can be mounted correctly and will not suffer from uneven pressure.

You need to discharge your phone’s battery below 25% before disassembling it. Your battery can catch fire and/or explode if it has been punctured, but the chances of that happening are much lower if the battery has been discharged.

We advise you only to replace the screen and leave the original frame and motherboard in place throughout this guide. You should note that some replacement screens for this phone come pre-installed in a new frame (a.k.a. chassis), which will require an entirely different procedure. Therefore, you should make sure you have the right part before beginning.

During the reassembling process, you’ll need a replacement adhesive in order to reattach components.

Listed below are some necessary tools that you will need before starting this replacement guide:

  • SIM Card Eject Tool
  • Opening Picks (Set of 6)
  • Heating pad
  • Spudger
  • Precut Adhesive Card
  • Adhesive Remover
  • Plastic Card
  • Suction Handle

Step 1 Eject the SIM tray of Galaxy A70

  • In order to remove the SIM card from your phone, you must insert an ejecting tool, a SIM eject bit, or the straightened end of a paper clip into the hole at the left edge of the SIM tray.
  • The tray will now eject, and you will be able to remove it.

Step 2 Soften the adhesive of Galaxy A70

  • Turn off your Galaxy A70 by pressing the power button.
  • You can soften the adhesive beneath the rear glass by heating a heating pad and using it to soften it. It should be heated for at least two minutes to soften the adhesive. It might be necessary to repeat this procedure several times during removing the rear glass.
  • Alternatively, you may use a hairdryer, heat gun, or hot plate as long as you do not overheat the phone, as the AMOLED display and internal battery can both be damaged by excess heat.

Step 3 Create a gap

  • As close to the right edge of the back of the phone as possible, apply a suction cup as close as possible to the center of the right edge.
  • Place the suction cup on top of the rear glass and pull back to create a gap between it and the frame.
  • You will need to place a pick in the gap.

Step 4 Slice the adhesive of Galaxy A70

  • Move the opening pick along the edge to the bottom right corner.
  • In order to prevent the adhesive from resealing itself, leave the opening pick in its place.
  • It is up to you whether to remove the suction cup once you have inserted the opening pick or if you would like to continue using it as a grip during the removal process.
  • Add a second opening pick under the bottom right corner of the book’s back cover.
  • You should move the opening pick along the board’s edge to the top right corner.
  • You can use the heating pad again if you have difficulty cutting the adhesive once it has been softened.
  • Ensure the opening picks are left in place to prevent the adhesive from re-sealing.
  • Make sure there is a third opening pick under the top right corner of the back cover.
  • In order to cut the adhesive, move the tip of the opening pick along the top edge of the phone.
  • In order to avoid the adhesive from resealing, leave the opening pick in the top left corner of the window.
  • Place a fourth opening pick under the top left corner of the board.
  • Use the opening pick to cut the adhesive by sliding it along the left edge of your phone.
  • In order to prevent the adhesive from resealing itself, leave the opening pick in its place.
  • Insert a fifth opening pick under the bottom left corner of the board.
  • Cut the remaining adhesive along the bottom edge by sliding the blade along the bottom edge.

Step 5 Remove the rear glass

  • In order to do this, you will need to remove the rear window.
  • For the adhesive to form a good bond, you must apply strong, steady pressure on the phone for several minutes after installing the back cover – a pile of heavy books works well.

Step 6 Unscrew the midframe

  • Take out the fourteen screws that are four millimetres long and hold the midframe in place using a Phillips screwdriver.
  • It is held in place by plastic clips attached to the midframe.
  • Near the volume button on the phone’s right edge, insert an opening pick between the midframe and front panel assembly.
  • Remove the plastic clips by sliding the opening pick to the bottom right corner.
  • As you continue to slide the opening around the bottom right corner to the bottom left corner, you will be able to separate the plastic clips.
  • To remove the plastic clips, slide the opening pick along the left edge of the pick.
  • The midframe should be removed.

Step 7 Disconnect the battery of Galaxy A70

  • You can easily remove the battery by prying the connector straight up from its socket with a spudger.

Step 8 Disconnect the display connector

  • It is possible to pry up the display connector and separate it from its daughterboard socket using the flat edge of a spudger.

Step 9 Apply a heating pad

  • The screen should be heated for two minutes by applying a heating pad.
  • Alternatively, you could use a hairdryer, heat gun, or hot plate, but you must be careful not to overheat the phone because both the display and the internal battery are vulnerable to damage from excessive heat.
  • You will need to apply a suction cup to the right edge of the display.
  • There is a possibility that the suction handle will not stick to the phone if the screen is cracked. You can try to lift the suction handle with strong tape, or you can superglue the suction handle in place and let it cure for a while before continuing.
  • Create a gap in the suction cup by pulling it up with a strong, steady force.
  • Using an opening pick, insert the tip of the pick into the gap.
  • To slice the adhesive, slide the opening pick to the bottom right corner of the pick.
  • To prevent the adhesive from resealing, leave the opening pick in place.

Continue to do so until you completely slive all the adhesive in order to remove the screen.

Step 10 Reapply a Heating pad

  • To loosen the adhesive underneath the screen, reapply a heated iOpener.
  • To loosen the adhesive underneath the screen, reapply a heating pad to the screen.
  • Avoid tearing the display flex cable by not using the plastic card underneath the bottom end of the screen.
  • In the gap between the display and the phone assembly, insert the left edge of a plastic card.
  • You must press the plastic card into the slot and slide it back and forth until you cut through the adhesives.
  • If you are sure that you have cut through the adhesive, you should remove the four picks from the corners once you are sure you have done so.
  • You should not remove the screen completely yet. There is still a cable threaded through the frame that connects the screen to the display.
  • Be sure to thread the display cable through the frame carefully not to damage it.
  • You should remove the screen.
