Direct answer: Only iPhone 7 and 8 series still have Home buttons — and each button is paired to its phone at the factory. Swapping one kills Touch ID unless you transfer the original button. Adhesive strips, by contrast, are cheap ($1–3), universal to stock, and mandatory for every screen and back glass job. Rule: always transfer the original Home button; always use fresh adhesive.
Which iPhones Have Home Buttons?
| Model | Home button | Touch ID re-pairable? |
|---|---|---|
| iPhone 6s / 6s Plus | Yes (mechanical) | No — paired |
| iPhone 7 / 7 Plus | Yes (solid-state) | No — paired to board |
| iPhone 8 / 8 Plus | Yes (solid-state) | No — paired to board |
| iPhone X and newer | No — Face ID only | N/A |
The hard rule: the Home button is soldered-paired to the logic board. A replacement button restores the physical click but Touch ID will not work — unless you transfer the original button or reprogram with specialized tools.
Home Button Replacement: What Shops Actually Do
- Screen repair on 7/8: always transfer the original Home button to the new screen. Never use the button glued to the replacement panel.
- Broken button: replace it and tell the customer Touch ID is disabled, or use a reprogramming solution if they insist.
- Torn flex: if the chip is intact, replace just the flex.
Transfer steps (during a screen replacement):
- Open the phone, unscrew the Home button bracket.
- Gently lift the button — it’s glued; heat 60 seconds if needed.
- Seat it into the new screen’s Home button cutout, press firmly, secure the bracket.
- Connect the flex, test the button, then test Touch ID in Settings.
Adhesive Strips: The $2 Part That Prevents $60 Callbacks
Adhesive is where callbacks happen. A screen sealed with old adhesive:
- Creaks and rattles — customers notice immediately
- Loses water resistance
- Collects dust under the glass
- Makes the next repair a nightmare
What to stock:
- Screen adhesive frames — one per model you service (iPhone 7, 8, X–13), $1–3 each wholesale
- Back glass adhesive — our back glass ships with adhesive pre-installed
- Universal adhesive kits — trim-to-fit strips for emergency jobs
ScrnFix carries adhesive strips for iPhone 7 and adhesive strips for iPhone 8, plus pre-adhesive back glass.

FAQ (People Also Ask)
Q: Will Touch ID work if I replace the Home button?
A: No. Touch ID is paired to the original button + logic board. A replacement button disables fingerprint unlock — transfer the original to keep it.
Q: Do iPhone 7 and 8 use the same Home button?
A: The buttons look similar but are not interchangeable — the flex and bracket differ. Match the exact model.
Q: How long does adhesive last once opened?
A: Once the screen is lifted, the original adhesive is compromised. Always use fresh adhesive — a $2 part that prevents a $60 callback.
Q: Does iPhone 8 have a Home button?
A: Yes — the 8 and 8 Plus are the last iPhones with Home buttons. The X removed it for Face ID.
Q: What adhesive strips do repair shops need?
A: Screen adhesive frames for every model you service, plus back glass adhesive and universal kits. They’re the cheapest consumable in the shop.
