iPhone 12s on AT&T and Verizon are losing 5G signals in the US
Some Apple customers have resorted to this OEM's support forum to report that their new iPhone 12s spontaneously drop the 5G signals for which they are marketed in 2020. Some of these users claim that this bug is accompanied by the loss of all bars and an on-screen notification that reads "Your iPhone is not Activated".
According to some of those affected, this new issue may be related to a switch in 5G service between the cell towers in question, or a change in reception from 5G to 4G/LTE. In a number of the cases reported, the customers are on the AT&T or Verizon networks in the United States. However, one user facing this adversity is from Australia.
In some instances, common fixes such as turning airplane mode on and off again addreses the problem, whereas none of them are reported to work in others. This is the latest in a list of teething problems for the Cupertino giant's latest premium smartphone series, one that includes numerous reports of the "green tint" issue. Apple has yet to respond to this latest bug at this time.
