How do smartphones use magnets?
By Daniel Moore
In flip phones, rare earth magnets are also used in the sensors that detect when the phone is opened or closed and that automatically switch the LCD screen On/Off and reduce the drain on the battery. Rare earth magnets are used in the mechanisms for image stabilization functions on digital cameras.

Also question is, are there magnets in smartphones?
The short answer is, if the magnet is big enough and strong enough it could damage your device, and not just by dropping the magnet on it! However, modern smartphones use LCD screens which are not generally susceptible to magnets, hurrah!
Furthermore, will a magnet pick up a cell phone? We still get asked every day -- "Will a magnet hurt my phone?" The simple answer is "NO." Apple iPhone and Android devices use NAND flash memory, which is immune to magnets. They do not use magnets for storage; instead, they use integrated circuit assemblies as memory to store data.
are magnetic mounts bad for your phone?
One of the most frequent questions is whether a magnetic car mount would wipe a phone. No, it will not for one simple reason. On the contrary, phones hold storage chips, which are a type of flash memory, and which are not affected by magnets. There are mentions on forums that iPods can be affected by a magnet.
Can a magnet erase a hard drive?

The most important use for neodymium is in an alloy with iron and boron to make very strong permanent magnets. This discovery, in 1983, made it possible to miniaturise many electronic devices, including mobile phones, microphones, loudspeakers and electronic musical instruments. Neodymium glass is used to make lasers.How strong is neodymium?
