Will the magnet hurt my phone?
All smartphones use flash based memory, and are not damaged by the magnet in the Perchmount Fit.
The magnet may cause interference with the wireless field created by NFC enabled smartphones, so for best performance, switch NFC off.
We recommend you do not use a Perchmount Fit with an iPod Classic, as it has a hard disk drive, and the magnet will likely cause damage.
