Home Button Outer for LG L90 D405 White - Plastic Key

The Home Button Outer is just the external cap — the visible, pressable surface of the Home Button on your LG L90 D405. The Home Button Complete is the full assembly including the cap, fingerprint sensor, flex cable, and bracket. If the button cap is cracked or worn but the fingerprint sensor and flex are working correctly, replacing only the Home Button Outer is the more affordable and less invasive repair on your LG L90 D405.

In most cases no — the fingerprint sensor is integrated into the button mechanism below the cap, not in the outer cap itself. Replacing only the outer cap on your LG L90 D405 should not affect fingerprint reading accuracy. However on some models the fingerprint sensor is embedded directly into the cap surface — on these devices replacing the outer alone may affect fingerprint function. Verify your LG L90 D405's specific design before ordering.

Yes — available in the original colour options for LG L90 D405. Select the colour that matches your device when ordering for a seamless cosmetic result.

Yes — in most cases the outer cap adheres or clips onto the existing Home Button mechanism. Carefully remove the old cap, clean the contact surface, and press the new one into position. On some LG L90 D405 devices the phone may need to be partially opened to access the retention mechanism properly.

Yes — a 7-day replacement warranty covering manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Caps with physical damage from installation attempts are not eligible for return. For more information, check out SAHII's Return Policy.
