Frequently Asked Questions

Does this flex include the plastic or metal external buttons of the Xiaomi Mi 9T Pro?
No. This component is strictly the internal flexible circuit with the electrical click contacts; the button caps visible on the exterior of the chassis remain those of the phone.

Is it necessary to solder the flex cable to the main board?
No soldering is required, as the circuit connection is made via direct pressure contacts on the device structure.
