On paper, the iPhone 18 Pro and iPhone 18 Pro Max represent the pinnacle of Apple engineering. The flagship devices boast the brand-new A20 processor, an ambitious camera module sporting variable aperture hardware, and what Apple advertises as the longest battery endurance ever seen on any iPhone. In spite of those high-profile specifications, the retail rollout for the iPhone 18 Pro family has experienced unexpected turbulence, characterized by an array of software glitches and hardware complaints. While certain early malfunctions have already received fast software remedies, other defects remain unresolved for affected handset owners.
None of these early manufacturing and software bumps necessarily mean customers should pack up their devices for returns or avoid the newest premium hardware entirely. Still, the commercial launch has been far from flawless. To date, four substantial technical troubles have been documented across both the iPhone 18 Pro and iPhone 18 Pro Max.
Spontaneous System Freezes and Random Reboots
The initial prominent flaw detected on the iPhone 18 Pro involved spontaneous system restarts. Owners noticed that whenever a Face ID authentication scan failed to recognize their face, the operating system would suddenly seize up and freeze. After lingering in an unresponsive state for several seconds, the handset would undergo an unexpected reboot. This issue was not confined solely to smartphones; the latest Apple Watch Series 12 and Apple Watch Ultra 4 encountered nearly identical reboot malfunctions around the same time. The underlying problem stemmed from a software conflict inside iOS 27 and watchOS 27. Apple swiftly deployed emergency bug fixes through iOS 27.0.1 and watchOS 27.0.1, with release documentation dedicated solely to resolving the restart glitch.
Cellular Outages and 911 Dialing Failures on Pro Max
While Apple framed iOS 27.0.1 as a dedicated fix for the restart flaw, telecommunications provider AT&T revealed a considerably more urgent concern. AT&T distributed high-priority alerts to its iPhone 18 Pro Max subscribers, insisting they update their operating system without delay. The carrier warned that affected customers could experience severe disruptions to phone calls, SMS messaging, and mobile data, with the potential failure even impacting calls placed to 911 emergency services.
The notification delivered directly to subscribers stated that an urgent software patch was available for the iPhone 18 Pro Max, warning that select units might be prevented from completing cellular calls, texts, and data transmissions, specifically including 911 calls. Subscribers were directed to navigate immediately into their phone settings to install iOS 27.0.1. Crucially, owners of the standard iPhone 18 Pro did not receive this warning. The operational divergence appears connected to the internal wireless hardware: the iPhone 18 Pro Max stands as the lone model in the generation utilizing a Qualcomm modem instead of Apple's in-house C2 chip. When the connectivity glitch strikes, the Pro Max drops cellular coverage entirely, forcing the device into SOS emergency mode.
Upper Speaker Crackling and Popping Audio Artifacts
Another issue troubling buyers of both the iPhone 18 Pro and 18 Pro Max involves bizarre acoustics originating from the front-facing speakers. Handset owners have documented recurring cracking and popping noises during everyday use. One customer described the distortion as sounding like an auxiliary audio cable being violently yanked out of a headphone port, noting that the sound emanated intermittently from the top earpiece speaker. Others echoed the problem, describing a distinct buzzing sensation when listening to media at 100 percent volume or annoying crackling interference during phone conversations while using the mono speaker configuration. Notably, installing the iOS 27.0.1 update failed to eliminate the acoustic glitch for several dissatisfied owners.
The audio issue does not appear universal, however. Various owners reported totally clear speaker output, having never encountered any unexpected noise artifacts. Interestingly, at least one user mentioned experiencing identical crackling noises on an older iPhone 16 Pro Max immediately after upgrading that hardware to the iOS 27 operating system, hinting at possible software-level sound processing conflicts.
Discoloration and Peeling Around the Camera Lenses
A fourth concern centers around physical build quality and surface resilience. Some iPhone 18 Pro and 18 Pro Max owners have observed cosmetic degradation, reporting that the exterior finish has begun wearing away directly around the camera rings. Nearly all reported incidents have surfaced on units finished in burgundy and black colorways. The overall prevalence of the cosmetic defect remains undetermined. While a handful of customers found that gently cleaning the area around the lenses with a cotton swab removed the marks, others confirmed that the protective outer pigment coating had genuinely eroded from the metal frame.
