Catalog updates

The app checks the cloud catalog when opened. You can also pull down on the home page to refresh. The first download requires a network connection; if it fails, check your connection and retry. Previously downloaded specifications remain available from the local cache.

Corrections

Email the brand, model, region, capacity, field to correct and a verifiable manufacturer or review link. Specifications and reference prices may differ by region and configuration; compare matching versions.

JD prices

The button opens a matching product or a model search. Reference prices are not live transaction prices. Products, availability and checkout prices are determined by JD. If no matching product link is configured, a model search is used.

Favorites and comparison

Favorites and comparison selections are stored locally and are not synchronized between devices. Compare up to two phones; when adding a third, choose an existing selection to replace.
