Problems With Magnetic Phone Cases

by Christa Titus

As of January 2011, magnetic phone cases---carriers that are held closed with magnets instead of a snap that you press closed with your fingers---were becoming popular for carrying cell phones. However, the magnets in these stylish cases can cause problems with your cell phone or even ruin it.


People who own iPhone 3Gs have reported problems with the magnets in relation to the phone's compass/magnetometer. Users had to recalibrate the feature to ensure its accuracy every time they removed the iPhone from its case, and it took longer to reset the compass/magnetometer each time.


Touchscreens of any kind should be kept away from magnetic fields. Magnets can cause temporary failure in touchscreens, even if the magnets are small. If the magnets are strong enough, permanent damage to the phone's touchscreen can result.

Back Light

When magnets come into close proximity with a phone, the circuitry inside may react by triggering the phone's back light to remain lit, even if you've adjusted your settings to turn the light off after using the phone. The phone might also react by displaying an unfamiliar screen.
