Samsung Galaxy A3 (2017) Display Replacement

• Power off your phone before beginning disassembly.
• Use an iOpener to loosen the adhesive beneath the back cover. Apply the iOpener for at least two minutes. You might want to repeat this step several times during the back cover removal.
  • The adhesive of the Samsung Galaxy A3 (2017) 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.

  • Use a small suction handle to create a gap at the bottom end of the Galaxy A3.
  • Insert an opening pick and slide the tip to the bottom left corner to cut the adhesive.
  • Leave the opening pick in the bottom left corner to prevent the adhesive from resealing.
  • Insert a new opening pick and start to cut the adhesive towards the bottom left side of the phone.

  • 

  Step 3

  • Use an opening pick to cut the adhesive on all sides of the phone. Leave one opening pick in every corner to prevent the adhesive from resealing.
    • Reuse an iOpener 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 loose enough.
  • Insert an opening pick on the right side of the phone after you cut the adhesive on all sides. Fip it sideways until you can get a good grip on the back cover.

• Prepare an iOpener and apply it to the display for at least two minutes to loosen the adhesive beneath.
  • You may need to reheat and reapply the iOpener several times to get the phone warm enough. Follow the iOpener instructions to avoid overheating.
• If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping over the glass.
  • Lay overlapping strips of clear packing tape over the display until the whole face is covered.
  • This will keep glass shards contained and provide structural integrity when prying and lifting the display.
  • Wear safety glasses to protect your eyes from any glass shaken free during the repair
  • 

Step 11

• Once the display is warm to the touch, apply a suction cup to the upper edge of the phone.
• Lift on the suction cup, and insert an opening pick under the display assembly.
• Start to slide the opening pick along the upper edge of the phone to cut the adhesive. Leave an opening pick at the corner to prevent the adhesive from resealing.
• Continue to cut the adhesive on the remaining sides of the phone and leave an opening pick in each corner.
• The home button and soft key cables are located beneath the bottom part of the display assembly. Only insert the tip of the opening pick.

Step 12

• The screen's flex cable is located right behind the volume buttons, and may interfere with your cutting tool.
• After cutting the adhesive on all sides of the phone, insert a plastic card beneath the display assembly to loosen any remaining adhesive behind it.

Step 13

• Don't open the phone all the way yet. The display cable is still threaded through the mid frame and you might rip the cables of the home and menu buttons.
• Start to carefully lift the upper edge of the display assembly and thread the display flex cable through the mid frame.
• Check if the home button or soft key button cables stick to the display assembly before your remove the display all the way.
  • In case one of the cables sticks to the display, carefully peel them off with a pair of tweezers or an opening pick.
• Remove the display assembly from the phone.
• Before reassembling make sure to remove any remaining adhesive from the frame by using isopropyl alcohol (>97%) and a lint-free cloth or Q-tip.
