![]() It enables your phone (if it has a GPS) to determine the location whilst you are out and about, so that you don't get lost. GPS is a crucial satellite navigation system that works using satellite signals to provide geolocation and time information to a GPS receiver. They have become technically more advanced with no reliance on magnetic fields to function, which means no more focused electron beams, no more 'Ford Escorts', oh and no interference from magnets! 3) Why is the GPS safe? Thankfully, today we have made significant progress with smartphone screens, IPS LCD screens, AMOLED and OLED screens. Consequently, any external magnet would interfere with these magnetic fields, resulting in an array of psychedelic colors displayed on the screen, fun for a while but not very good for the screen. In the old days, when mobile phones were the size of cereal boxes and PC monitor cases were roughly the same size as a "Ford Escort", they were very susceptible to magnetic interference.īack then, CRT monitors would generate a picture by shooting an extremely focused electrons beam at a phosphorous coated glass screen and bend the beam horizontally and vertically using magnetic fields. If you wanted to know if the magnet was affecting your phone or not, the easiest way might be to place a magnet on the screen and see if the image is distorted or not? In contrast, the speakers are located on the edges and therefore not affected by the magnetic field. Likewise, when you put your phone on the magnetic mount, the magnetic field is small and located near the phone center. However, as Matt explained, "the vast majority of magnets that you come across day to day, even many of the super-strong ones on the market, will have no adverse effect on your smartphone".Īs previously mentioned, the only time that the speaker would only be affected is if you were making a call otherwise, it has no impact. When it comes to magnetic interference, the speaker, the screen, the GPS module, the inbuilt compass, and the phone's cell signal are most likely to be affected. ![]() Why won’t a magnetic phone mount damage your smartphone? So, there is nothing to worry about!Īt this point, you are probably thinking, will my magnetic smartphone mount really damage my smartphone? Let’s dig a little deeper. You see, only a powerful magnetic field can affect your phone, and you would have to continuously use your phone's compass or make calls for a long time (months or even years) in the presence of a strong magnetic before they would become affected. It is true that they can be affected, but nowhere near to the extent that you might think. You will find lots of forum threads about how the electronic compass in your smartphone can be affected by magnetic phone mounts, or to be specific, the magnets inside them, but is this true? Take the electronic compass and speaker as examples. The components or apps will not be affected if you don't use your phone near a strong magnetic field. In case you are not clear, they won't do anything to your credit card they are so small that they can't even pick up a paperclip. Many people asked questions like: can a credit card be demagnetized by a phone?. Even the Apple Watch uses a magnetic induction wireless charging system to ensure that the watch is aligned to the charging dock. ![]() You may already be aware that your smartphone has a number of magnets inside, for example, the speaker, the camera and the vibration module, none of which would work without magnets. Most smartphones already have several magnets inside them. Nothing changes (at least not this time, it's a strong magnet anyways). ![]() The guy uses a super strong neodymium magnet near the iPhone whilst testing that it can still send SMS messages, take calls, use the compass and even attack it with loads of other magnets. ![]() To make you feel even more confident that magnets will not affect your smartphone, check out this video. The typical type of magnets embedded in a smartphone mount is usually tiny, discrete and not capable of interfering with your device's signal or data. Today, you will find a wide variety of different magnets used in many different situations, each one specifically designed for the task required-for example, the refrigerator and microwave oven. ![]()
