Multiple iPhone 12 Users Report Sudden Drops in 5G and LTE Cellular Coverage

Since Apple launched the iPhone 12 in October, an increasing number of users of the new smartphone have been reporting persistent drops in cellular coverage.

Multiple reports of dropped 5G and LTE connectivity have appeared on Reddit, on Apple's support forums, and on the MacRumors forums, with many people suffering issues when walking or in transit and some seeing the same problem when stationary.

Several users report suddenly losing all reception bars and seeing a "no service" message on their ‌iPhone‌ 12, despite being in an area of network coverage and seeing no connectivity issues on other devices, and iOS version doesn't seem to be a factor.

Several users have been in touch with Apple technical support or their operator, and there's some suggestion that the issue may be related to how the ‌iPhone‌ 12 switches between cellular towers. Affected iPhones reportedly pass all of Apple's diagnostic tests, while toggling Airplane mode on and off seems to correct the lost signal reception for some, but not all users.

‌iPhone‌ 12 users in various countries have relayed their experience with the problem, and it doesn't appear to be related to any one network carrier, with reports from users across Verizon, AT&T, and T-Mobile. Verizon is said to be aware of the issue.

Have you seen similar sudden dropped connections on your ‌iPhone‌ 12 for no apparent reason? Let us know in the comments below.

(Thanks, Wesley!)

Hey Macrumors, more than multiple users are also reporting receiving iPhones 12s (all 4) with yellow tinted screens. Please report on that.

7 people can’t handle their iPhone, if they even have one, must be a disaster! You’ve got to be kidding me. I’ve had great 5G coverage from day 1.
One person has had a great experience, so everyone else's is invalidated. Right?

I get that every year there are issues, and I get the old saying about first gen Apple anything, in this case something related to the 5G perhaps, but between this and the other issues I’m reading about, my gf and I are holding off for the 13.

I know, I know, there are plenty of users who are just fine, but......
But then the 13 will have something wrong as well. Lol

Same problem here in germany. Call drops with both major carriers o2 and telekom in a dual sim setup. Annoying as hell.
