Apple iPhone 11 family troubleshooting
Apple iPhone 11 family (A2111/A2221/A2223/A2160/A2215/A2217/A2161/A2218/A2220): green tint at unlock; a seven-year-old battery; no 5G on the iPhone 11; still on current iOS, and a fix for each symptom below.
- Green tint at unlockA small number of iPhone 11 and 11 Pro owners reported a green tint for a few seconds after unlocking, noticed since iOS 13.4.1, which some tied to software. A solid green line that stays is different: it is a failed display and needs a screen replacement.

What is true of this model and changes how you fix it
- A seven-year-old batteryThe iPhone 11 launched in 2019, so a short battery life is almost always the battery; Settings, Battery, Battery Health shows it, and the phone still runs iOS 26.
- No 5G on the iPhone 11The iPhone 11 has no 5G modem, so it falls back to LTE in areas a carrier serves only with 5G, and a slow connection there is the hardware, not a setting.
- Still on current iOSIt runs iOS 26, so an app that refuses to install is asking for something the phone lacks, not an old iOS.

Exact questions
Questions that only have an answer for the Apple iPhone 11 family
Why is there a green line on my iPhone 11 screen?+
A line that stays is hardware damage to the display or its connection, and restarting or resetting does not clear it. A screen replacement does.
Does the iPhone 11 support 5G?+
No. It connects over LTE, so it will not use a carrier's 5G network.
