Reviewers found that the Verizon Wireless-connected device, released earlier this month, has a similar problem with dropped calls that the AT&T iPhone did.
In areas with a weak signal, users who block the tiny gap in the lower left side of the metal band surrounding the phone can experience connectivity issues, according to a Consumer Reports blog post. Palming the phone, a natural position, can cause the problem, typically within 15 seconds.
As it did with the AT&T version in July, reviewers said they didnâ€™t recommend the Verizon iPhone 4. But they said that using the phone with a case alleviates the problem and that the product â€œperforms superbly in most other respects.â€
Consumer Reports engineers ran the same lab tests they use on other smart phones, throwing in a few extra ones that they developed after the initial round of dropped-call complaints.
