iPhone 16 Pro Max display screen glitching with vertical lines

The glitching problem happened again and I was given a brand new iPhone 16 Pro Max as replacement. The new replacement also glitched with vertical lines very soon thereafter. 

You got a brand new iPhone 16 Pro Max from Apple Inc. The issue continues on the new device too.

Since the issue persists even on the new device, it might point to a deeper problem like environmental (like interference).

1. Does this occur with other people too in the area where you live?
2. Have you Jailbroken your device?
3. Have you noticed if this glitch happens more often in specific locations, apps, or usage scenarios?
4. Is your iOS fully updated? 

It's wise to consider potential contributing factors beyond just inherent hardware defects. Here's a look at environmental factors and software modifications:

Environmental Factors:

1. Extreme Temperatures:
   1. iPhones, like all electronic devices, are sensitive to extreme heat and cold. Excessive heat can definitely cause display issues and other malfunctions. If the phone is frequently exposed to very high temperatures, especially direct sunlight, this could be a factor.   
   2. Conversely, extreme cold can also affect the display's performance.   
2. Humidity: High humidity can lead to moisture buildup inside the device, potentially causing electrical shorts or corrosion that could affect the display.   
3. Strong Magnetic Fields: While less common, strong magnetic fields can interfere with electronic devices.   
4. Static Electricity: In very dry environments, static electricity buildup could potentially cause temporary glitches.

Jailbreaking and Spurious Software:

1. Jailbreaking:
   1. Jailbreaking an iPhone removes Apple's software restrictions, allowing users to install unauthorized apps and modify the operating system. This significantly increases the risk of software instability, conflicts, and malware infections, all of which could lead to display glitches.   
   2. If the device has been jailbroken, the software is likely a strong contributing factor. Apple also will usually not support a jailbroken device.
2. Spurious Software:
   1. Even without jailbreaking, installing apps from untrusted sources can introduce malware or poorly coded software that interferes with the display drivers or other system functions.   
   2. Corrupted iCloud backups can also cause software issues.

In summary, while environmental factors and software modifications can contribute to display issues, the fact that you've experienced this problem on multiple replacement devices strongly suggests the area and how the device is being used.

Dear Mutu, thank you for bringing up this issue. I have the same problem with my brand new iPhone 16 Pro Max (bought 15/03). It is now updated to iOS 18.4 and this issue is still there.

I am following this thread with interest hoping there will be a solution to this.

Thank you again
