    • Slide the opening pick all the way to the bottom left corner of the phone, making sure it is securely placed.

    • Place a reheated iOpener over the bottom portion of the display assembly.

    • There are delicate components in this portion of the phone, you want to ensure the adhesive is warm and easy to loosen to protect the phone.

    • The bottom end of the phone contains the soft button and home button ribbon cables. If you insert the opening pick too far into the phone you risk cutting these cables.

    • Slide the very end of the opening pick across the bottom edge of the display to separate the last of the remaining adhesive.

    Modifier

    Modifier

    • If the front panel is not easily freed, the adhesive on the soft button cable may need to be separated.

    • These cables are thin and easily damaged, therefore be certain you are only peeling them off the display assembly and not lacerating them.

    • Insert an opening pick under the soft button icons on the display and pry the button cables down off the inside of the front panel.

    Modifier

  16. Samsung Galaxy S5 Fingerprint Reader Replacement: étape 15, image 1 de 2 Samsung Galaxy S5 Fingerprint Reader Replacement: étape 15, image 2 de 2

    • Slightly lift, but do not remove, the home button end of display assembly.

    • Do not remove the front panel entirely. It is still attached by a connector.

    • If you are reusing the home button flex cable, be careful not to sever the cable from the home button. Adhesive can cause the cable to rip apart from the home button. While the home button will still work, the fingerprint scanner will not.

    • Use the sharp tip of a spudger to lift the front panel assembly cable connector straight up off its socket on the motherboard.

    • Safely remove the front panel assembly from phone.

Good guide, but how to apply new adhesive for the lcd display on the midframe ?

Arnoud - Réponse

It should already be attached to the LCD, if not then you can purchase the adhesive and attach it to the LCD yourself

Patrick Lee -

I would like to know whether there is a pin-compatible home button to replace the original Galaxy S5 home button to _physically_ get rid of the fingerprint reader unit and solely keep it as a simple and dumb home button.

Thanks in advance.

E.Remarque - Réponse

It should be noted that unlike replacing an iPhone Home Button, you can reprogram a replacement Galaxy Fingerprint scanner.
