Frequently Asked Questions

Is this flex cable compatible with the Honor 90 Lite or Honor 90 Pro?
No. This component was designed exclusively for the Honor 90 (models REA-NX9 and REA-AN00), and is not compatible with other variants of the series.

Does replacing this flex resolve charging issues?
If the charging failure originates from a broken track or damaged connector on the current flex, the replacement resolves the issue. If the fault is on the lower charging board or the motherboard, it will be necessary to diagnose those components.
