Having a faulty home button is a common problem on the iphone 4. There are a few different symptoms which indicate a problem with the iPhone 4 home button or home button circuit. If your home button isn’t functioning at all, then it is likely that you need to replace the home button circuit, however you should also check to make sure the iphone 4 charges when connected to a charge cable. If the iPhone 4 isn’t charging then you need to buy an iPhone 4 dock connector. The home button circuit attaches to the dock connector, so if the dock connector is faulty, the home button won’t function even if the home button circuit itself isn’t broken.If your iPhone 4 home button sticks down or doesn’t click replacing the home button and circuit will fix this. The home button circuit becomes worn out over time and also dirt and moisture can work their way under the home button causing corrosion and sticking.
If the voice control is turning itself on, this is also another symptom of the iPhone 4 home button and circuit needing replacement. Normally holding the home button for 3 seconds will activate voice control, so if voice control is coming on by itself it means the home button circuit is shorting out or maintaining a connection even when you aren’t pressing the home button.
If you have cracked your screen near the home button and have used it while it is cracked, you may also find that your home button has stopped working. This is caused by either the cracked glass slowly cutting through the home button circuit underneath or because the cracks create a path for moisture to enter and cause corrosion to the home button circuit.
If you are replacing an iPhone 4 Touch Screen and LCD assembly, it is always a good idea to have a home button circuit available, because it is not hard to break the home button circuit while taking out a broken screen.
So if your iPhone 4 has any of the symptoms listed above be sure to pick up an iPhone 4 Home Button Replacement including Home Button Circuit today.
