The release of the iPhone 18 Pro and iPhone 18 Pro Max brought significant excitement thanks to innovations like the A20 chip, new cameras with variable aperture, and impressive battery longevity. Despite these upgrades, many early users have encountered a variety of issues—both in software and hardware—dampening what was expected to be a landmark launch. Complaints have surfaced about device reliability, with reports citing incidents from surprise restarts to day-to-day functionality obstacles.
Swift Fix Released for Rebooting Malfunction
Soon after the phones became available, a troubling glitch affecting the iPhone 18 Pro surfaced, involving the phone randomly freezing and then rebooting—often right after Face ID failed to authenticate. Notably, this random rebooting wasn’t exclusive to the latest iPhones; new Apple wearables like the Series 12 and Ultra 4 Apple Watch, also on their latest software, were affected by a similar issue.
To resolve this, Apple introduced iOS 27.0.1 and a matching watchOS 27.0.1 fix. The company confirmed that these releases directly tackled this singular bug, with no acknowledgment of additional alterations or improvements in the official update documentation.
AT&T Warns Users Over Emergency Call Glitches
Alongside the reboot concerns, a critical connectivity problem was identified with the iPhone 18 Pro Max: some units couldn’t maintain network connections or complete calls, even to 911. In response, AT&T advised its customers with the iPhone 18 Pro Max to immediately install iOS 27.0.1, warning that intermittent failures could hit voice calls, messaging, and data services, with the potential to jeopardize emergency call access.
The warning from AT&T did not extend to the iPhone 18 Pro. Analysis from MacRumors points to possible hardware differences: only the Pro Max employs a Qualcomm modem, while the rest of the lineup, including the smaller Pro, uses Apple’s C2 modem. Reports indicate that affected Pro Max devices can lose network connection entirely and drop into SOS mode until reconnection occurs.
User Reports: Speaker Problems and Cosmetic Wear
In addition to core operational concerns, many new purchasers are flagging various hardware annoyances. Several users, posting in a Reddit discussion, have described hearing crackling or popping from the speakers of both the iPhone 18 Pro and Pro Max—issues most pronounced at maximum volume or while on calls using mono mode. Buzzing and sporadic speaker noises have also been described, but some buyers, including several from Mashable, have reported no such problems. These sound issues have sometimes appeared after updating to iOS 27.0.1, while at least one user experienced similar glitches on the prior generation iPhone 16 Pro Max after loading the new operating system.
Another complaint centers on unusual discoloration near the camera lens in certain devices. Numerous posts, highlighted by Mashable, highlight this issue is mostly seen in burgundy and black versions. While a few owners found they could lighten the markings using a Q-tip, some stated the finish seemed actually worn away. The scope of the issue remains unclear, but more users have posted visual evidence and concerns on forums, such as in this Reddit post: “Is this discoloration around the camera lens rings normal on my new 18pm”.
Industry Watch: Ongoing Issues and Software Solutions
For now, Apple’s quick update has eliminated the critical reboot problem for the iPhone 18 Pro, Pro Max, and new Apple Watches. However, other challenges—specifically cellular instability and hardware quality, such as speaker defects and camera ring discoloration—continue for some users despite the most recent software fixes.
As the adoption of Apple’s newest products continues, industry analysts and consumers alike are monitoring whether future updates will fully resolve these recurring issues or if more problems will be revealed. Until then, Apple and AT&T recommend keeping devices updated with the latest software to help minimize risks, especially those tied to emergency call access and daily reliability.
