13 steps

Switching off your Samsung Galaxy S10
Keep the Power button pressed until the option "Switch off" is shown on the display.
Confirm the "Switch off" with your finger and wait until the screen is black.
Heating up the back cover
Used tools

Heat gun
The back cover is firmly glued. To loosen it, you have to heat it up first.
First turn your Galaxy S10 with the display side down.
To avoid scratches on the display screen, you should place your device on a clean, soft surface.
Use a hot air device, such as a heat gun or a regular hairdryer, and drive it evenly over the edge of the back cover from the outside.
As a rule of thumb, heat the edge of the back cover only to the point where you can still touch it without burning your fingers.

iFlex Opening Tool

VAKUPLASTIC Suction Cup
Once opened, your Galaxy S10 is no longer waterproof, and the warranty for protection against dust and splashing water expires.The backcover is made of glass and can break very easily. Therefore, be extra careful and take your time.
Place a suction cup at the bottom of the backcover and pull it upwards to create a narrow gap between the backcover and the housing frame.
Insert a flat, sturdy tool into the created gap. Try to enlarge the gap by pushing the backcover with the tool additionally upwards. We use the iFlex for this.

Flat Picks

iPlastix Opening Tool
Take care not to insert your tool too far, so that you do not damage anything under the backcover.
Use a flat plastic tool to go around the edge of the housing piece by piece. We use the iPlastix for this.
The iFlex is made of thin, sturdy metal, making it easier to get into the gap between the back cover and the case frame. However, the sharp edges of the iFlex make it easier to scratch the frame. We therefore recommend that you use the iFlex only initially and continue with iPlastix, which is made of flexible plastic, as soon as possible.
To prevent the adhesive from rebonding in the areas that have already been loosened, you should always heat the edge of the display and leave individual, flat picks in the device frame.
Remove the detached back cover and put it aside.
