  • Once the gap has been formed, insert an opening pick within it.

Step 4 Slice the adhesive

  • Place a second opening pick under the bottom right corner of the back cover.
  • Place the top right corner of the pick over the opening pick.
  • If you have difficulty cutting the adhesive, you can use the heating pad again to soften it.
  • Keep the opening picks in place to prevent the adhesive from resealing.
  • Under the top right-hand corner of the back cover, insert a third opening choice.
  • To cut the adhesive along the top edge of the phone, slide the tip of the opening pick along its edge.
  • To prevent the adhesive from resealing, you should leave the opening pick in the top left corner.
  • Add a fourth opening pick under the top left corner of the board.

Step 7 Insert an opening pick

  • to separate the midframe from the plastic clips that have been attached to it.
  • You should insert the opening pick between the midframe and the front panel assembly on the phone's right edge near the volume button.

Step 8 Detach the clips

  • Slide the opening pick to the bottom right corner of the opening pick to remove the clips.
  • As you slide the opening around the bottom right corner to the bottom left corner, you will be able to loosen the plastic clips.
  • Detach the plastic clips from the opening pick by sliding the pick along the left edge of the pick.
  • Now you can remove the midframe.

Step 9 Disconnect the battery of the Samsung Galaxy A70

  • You can dismantle the battery with a spudger by prying the connector straight up from the socket with the help of the spudger.
  • Using a spudger, pry the interconnect cable straight up from its socket by using the connector straight up from the motherboard.
  • Using a spudger, pry up the connector straight up from its socket to disconnect the interconnect cable from the connector socket on the daughterboard.
  • Once this has been done, the interconnect cable will be removed from the board.

Step 10 Apply adhesive remover

  • Putting a few drops of adhesive remover or high concentration (90% or higher) isopropyl alcohol into the gap at the bottom edge of the battery is recommended.
  • To remove the adhesive from underneath your battery, raise the bottom of your phone and tilt it in the direction of the rear camera. It will allow the adhesive remover to spread out.
  • It would help if you let the adhesive remover penetrate the battery adhesive for at least one minute.
  • The soft-shelled lithium-ion batteries can leak dangerous chemicals, catch fire, or even explode if they are damaged. It is recommended that you do not use excessive force or pry at the battery with metal tools. While doing this, make sure that you don't deform the battery in any way.
  • Place a piece of plastic underneath the bottom edge of the battery.
  • Slide it carefully under the battery to loosen the adhesive.
  • As you continue to slide the plastic card underneath, you will be able to pry out the battery from its recess.
  • When you do this, you should be able to remove the battery easily. If the battery is still sticky, repeat the previous adhesive removal procedure using the adhesive remover.

  • If your battery is damaged or deformed, do not reinstall it because it could risk your safety.
