Confirm the model first

Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Model numbers and patterns: SM-F956*
What that covers: Foldable device; distinguish cover display, main display, hinge and S Pen behavior.

Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Type — book-style FOLDABLE (crease is normal): A foldable with a small outer cover screen and a large inner folding screen. A visible CREASE down the middle of the inner screen is normal on all book foldables — it is where the panel bends, not a defect. Flex mode props it half-open for hands-free use.
Inner screen care & S Pen: The inner folding screen is a soft plastic-topped OLED — never use a hard/standard stylus or press hard; it supports only the specific Fold-edition S Pen (not the Ultra's). Do not force objects into the fold. IP48 rating resists water but NOT dust, so keep grit out of the hinge.
One UI / Android: One UI optimised for the large screen (multi-window, DeX). eSIM + physical SIM.

Exact questions

Questions that only have an answer for the Samsung Galaxy Z Fold6

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

There's a crease/line across the middle of my Galaxy Z Fold6 screen.+

That is normal and expected on every book-style foldable — the inner screen is a single flexible panel that bends at the hinge, leaving a visible and slightly feelable crease down the centre. It is not a crack or a defect. What is NOT normal is a spreading line, a black bar, or the screen lifting at the fold, which would indicate damage — often from dust in the hinge (the Fold6 resists water but not dust) or using a hard stylus. Use only the Fold-edition S Pen on the inner screen.

Structured depth, not empty permutations
