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 normal)
- OnePlus's book foldable — cover screen plus a large inner folding screen, with a notably subtle crease but still a normal bend line, not a defect. OxygenOS over Android with foldable multitasking (Open Canvas).
- Inner screen care
- Soft-topped inner OLED — no hard styluses, no pressing hard, no forcing objects into the fold. Keep grit out of the hinge; check its IP rating before water.
- SUPERVOOC fast charging
- Fast wired SUPERVOOC charging with the OnePlus charger + cable. eSIM support varies by region.

Exact questions
Questions that only have an answer for the OnePlus Open
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.
Is the crease normal on my OnePlus Open, and can I use a stylus?+
Yes, a centre crease is normal on any book foldable — the OnePlus Open's is unusually subtle, but the inner screen still bends at the hinge, so a faint crease is expected, not a defect. Do not use a hard stylus or press hard on the soft inner screen, do not remove its factory inner screen protector, and keep debris out of the hinge. A spreading line or lifting screen would indicate damage rather than the normal crease.
Structured depth, not empty permutations
