Vertical green line on display
A single (or multiple) bright green vertical line running top-to-bottom — most common on iPhone 11/12/13 and Samsung Galaxy S20/21/22/Note after a drop, pressure, or sometimes after an iOS / One UI update.
- ── What we replace
- LCD ribbon flex re-seat or LCD panel module swap, depending on root cause. We try the cheaper path first.
- ── Common on
- iPhone 11 / 12 / 13 / 14 series, Samsung Galaxy S20/S21/S22/Note 20, Xiaomi Mi/Redmi flagships.
- ── Notes
- If the line appeared straight after an OS update with no impact, often a reseat fixes it without a panel swap.
