On Reddit and Apple’s support forum, many iPhone 12 users complain that their devices have begun to lose cellular signal. Some people observe this behavior of the device in motion, and some users claim that their iPhone 12 loses the network even while in one place.
Smartphone owners claim that their iPhone 12 displays a “no network” message even in places where other devices show consistent reception. Empirically, it was revealed that this nuisance has nothing to do with the installed version of iOS. This is hypothesized to be related to the way the iPhone 12 switches between cell towers. The affected devices are reported to pass all of Apple’s diagnostic tests, indicating that they are working properly. Turning flight mode on and off often solves the problem.
The reason for the loss of signal has nothing to do with the cellular operator. Unfortunately, no solution has yet been found. Apple hasn’t made an official statement on this either. Recall that the owners of the iPhone 4 complained about the loss of the cellular network signal back in 2010. Then it was revealed that a certain grip of the smartphone affects the level of reception. Apple has advised iPhone 4 owners to “properly” hold their devices or to use special silicone bumpers. This phenomenon is called Antennagate.
