TL;DR: Some iPhone 17 Pros have a slight blue hue tint depending on who made the screen. Samsung panels are the best ones to get (serial numbers starting with G9P, G9N, or G9Q). Apple killed the old sysdiagnose method in iOS 26, but you can now use the free tool 3uTools on Windows or Mac — no jailbreak needed.
With the iPhone 17 Pro, Apple is sourcing OLED panels from different manufacturers. It’s a bit of a lottery — some phones end up with Samsung panels (considered the best), while others come with LG or BOE panels. The catch? A few non-Samsung screens show a noticeable blue tint.
The easiest way to check? Use 3uTools.
- Runs on both Windows and Mac
- Works perfectly on iOS 26 (as of Sept 25, 2025)
- Doesn’t need a jailbreak
- Spits out your hardware info in seconds, including the display’s serial prefix
Look for G9P, G9N, or G9Q in the serial number — that means you’ve got a Samsung panel.
Apple used to let us pull this info by digging into sysdiagnose logs, but they shut that down in iOS 26. Thankfully, 3uTools makes it super easy. I haven’t had the time to play with all its extra features yet, but for this one purpose alone it’s worth grabbing.
Big shoutout to the developers for keeping it free!
