In that case, normal taps won’t help you.
To fix magnification, hold three fingers together and then use them to double-tap the screen.
If your screen is magnified, this will bring it back to the normal view.
Turn off magnification inSettings>General>Accessibility>Zoom>Off.
Hard Reset the iPhone
Often the best step to fix any iPhone problem is torestart the iPhone.
In this case, you need a slightly more powerful restart called a hard reset.
Keep holding until the screen flashes and the Apple logo appears.
Let go of the buttons and let the iPhone start up like normal.
On those models:
Press thevolume upbutton and let it go.
Press thevolume downbutton and let it go.
Hold down thesleep/wake(akaSide) button until the phone restarts.
When the Apple logo appears, let go of the button.
It may take a while, but keep holding until the screen turns off.
Continue holding those buttons until the Apple logo appears.
Obviously this only works with iPhone models that have a Home button.
No word yet if there’s an equivalent to this option on those models.
Recovery Mode is a powerful tool for getting around whatever software problems you may be having.
It will let you reinstall the iOS and restore backed-up data onto the iPhone.
Plug the syncing cable into the iPhone, but not into the computer.
If the screen turns from white to black, you’re in Recovery Mode.
Restore your phone from back up.
For example, you might get the4013 iPhone error.
This is more complex and tricker, but it’s worth trying if nothing else has worked.
To put your phone into DFU Mode:
Connect your iPhone to your machine and launch iTunes.
Turn off your phone.
Hold the buttons for 10 seconds.
If you see the Apple logo, you held it for too long and should start over again.
After 10 seconds, let go of the sleep/power/Side button, but keep holding the other button.
If your phone’s screen is black, you’re in DFU mode.
If you see an iTunes logo, you should probably start again.
You should contact Apple tomake an appointment at your local Apple Storefor support.
Luckily, the solutions for an iPad or iPod touch White Screen are the same.
