Iphone 13 Max screen not working after IOS 16.4(a)
The screen on my phone is no longer showing color. This happened after the update to IOS 16.4(a)
iPhone 13 Pro Max
Probably you meant iOS 16.4.1 (a)
If the issues you have described are a direct result of the iOS 16.4 or iOS 16.4.1 or iOS 16.4.1 (a) update, it is highly likely that a substantial number of users who have performed the software upgrade are encountering a similar problem.
Based on my understanding and experience, it is highly unlikely that iOS updates would introduce issues that affect the day-to-day functioning of the device. iOS updates are typically designed to enhance performance, address security concerns, and introduce new features, rather than causing operational difficulties.
Without a precise understanding of the underlying issue, it may be challenging for forum members to provide targeted solutions to the difficulties you are encountering.
