iPhone Home Button Not Working
* IMPORTANT: Only the original iPhone's home button is capable of using Touch Id function. Installing a new home button (included with some LCD screens) will restore all standard functions, but NOT Touch Id fingerprint features. To get Touch Id, you will need to transfer home button from your original screen.
Here are troubleshooting tips for iPhone Home Button not working after screen is replaced. There are a few problems it could be.
1. Reset The Phone
Doing a full restore on the phone’s software can sometimes help. Back up your phone, reboot your phone into DFU mode and perform a complete restore. In a lot of cases, this will fix your home button wonderfully without any hardware work.
2. Check The Cables
The home button and 3D touch share a single cable that leads to your phone’s internals. Problem can also be caused by the home button’s extension flex cable running through the back of the lcd, and/or a damaged camera/speaker flex cable on top. So make sure to check all those cables out carefully These cables are incredibly fragile. To check it, you’ll have to remove the metal plate that’s behind your screen. If there’s damage to this cable, you’ll have to replace your entire backlight.
3. Check the Screw
The screw behind the home button is shorter than the other screws. Make sure you have the right screw. Loosen the screw behind the center of the home button (holding it to the metal bracket). The screw can be too snug. Some have removed that single screw completely.
4. Disconnect the battery
With old screen/connections attached, disconnect the battery then reconnect your new LCD and home button circuits before connecting the battery again. Battery must be disconnected before repair starts and ANY connectors removed.
5. Check Home Button with Original Screen
Change things around with your phone and see what happens. Does the old home button still work with the old screen?
6. Turn On Assistive Touch
While it’s not necessarily an ideal solution, you can turn on a software home button rather than rely on the physical one that failed. When you turn on Assistive Touch, your phone’s operating system will put a virtual home button at the bottom of your screen. It’ll give off a little buzz when you touch it to simulate the feeling of your physical button.
To turn on this feature, use one of these methods:
1. Tell Siri: “Turn on Assistive Touch”
2. Go to Settings -> General -> Accessibility -> Assistive Touch. Turn it on.
This will work for any situation where you find your iPhone home button not working.
iPad Home Button Not Working
* IMPORTANT: Only the original iPad's home button is capable of using Touch Id function. Installing a new home button (included with some screens) will restore all standard functions, but NOT Touch Id fingerprint features. To get Touch Id, you will need to transfer home button from your original screen.
1. If replacing the home button during a repair, and it doesn't work, make sure the home button is on straight. If the home button is crooked won't make contact with both pins. To correct, you may need to take off home button and straighten it.
2. Make sure you have all the components correct in the home button assembly. Here are typical components and position: Glass, spacer, button, soft gasket then holding bracket. You can transfer or purchase home button components from the original screen including the gasket or spacer and bracket. If transferring gasket, apply a little heat.
3. Make sure you're also using the plastic spacer ring. It positions the button at the proper depth and helps prevent the edges of the button from catching under the glass. These are delicate so be careful or they can tear. A new gasket may also help to hold button better.
4. If working with a new home button and having trouble. You may want to go back and transfer the whole home button from the old screen to the new one.
5. You may need more and stronger adhesive: Clean the bracket and the glass where the home button bracket sits with isopropyl alcohol. Apply adhesive on the bracket to secure. We can provide this if you need. Some repair technicians use B7000 liquid glue on the left and right hand side edges of the bracket. And let the glue set for 24 hours.
If home button not working after repair or during use, try this to get it to work before you open device. Helps if home button is stuck, jammed, lagging or unresponsive or broken -
