The iPhone 18 Pro has faced a series of reports about various issues in the first weeks after its release.
According to ITNA citing Phonearena, users have reported discoloration around the camera rings, network connectivity disruptions, speaker crackling, green and pink lines on the display, Face ID problems, and even issues related to UI smoothness. Some of these cases remain limited to a small number of users and some problems have been resolved with software updates, but the number of reports has attracted considerable attention.
One reported issue is color change around the camera on some iPhone 18 Pro and Pro Max units. Apple has offered replacements for some devices with this problem, but stock shortages have caused some users to wait until mid-October to receive a replacement device.
In communications, Apple has also had to replace a number of iPhone 18 Pro Max units that could not connect to the AT&T network. The US version of the iPhone 18 Pro is the only model that uses a Qualcomm modem, and this has made that component one of the likely suspects for the problem.
Some users have also reported speaker crackling, and in some cases, replacement devices have suffered the same issue. Reports of green or pink lines on the display have also circulated, although the credibility of some of these reports has been questioned.
Another contentious matter concerns the 1TB and 2TB models. According to published reports, these models may use QLC flash memory instead of TLC. QLC memory is cheaper, but has lower read/write speeds and shorter lifespan compared to TLC. Ordinary users will probably not notice much difference, but those who move large files or ProRes and 4K videos may experience slowdowns or even disruptions.
The redesigned Face ID has also drawn criticism. To make the display notch smaller, Apple moved the Face ID Infrared Flood Illuminator under the display. This change has reduced pixel density in the top area of that system, and some users say pixels in this region are visible to the eye. Using matte or privacy screen protectors may also impair Face ID performance due to reduced infrared transmission.
Overall, some of the iPhone 18 Pro problems likely stem from early units and software bugs, and Apple has addressed some cases with updates or device replacements. Nevertheless, the accumulation of these reports has raised questions about quality control of Apple’s new flagship generation. Despite these issues, the iPhone 18 Pro remains a high-end phone in terms of camera, battery life, and steady performance.
