Frequently asked questions

Does this part fit other OnePlus models?
No. It is specific to the OnePlus Nord. Other models have different dimensions, connectors or pinout.

Do I need special software or calibration?
No. The part works straight away — no flash, no calibration. The phone picks it up on the next boot.

What's the minimum toolset needed?
A Phillips PH00 screwdriver, a plastic spudger and a suction cup are usually enough. For screen or glass work a heat mat or hair dryer helps.
