1P 7.9.3 on Samsung device not limiting search to titles

Hello @johann_koebbe, thanks for your question!

For as long as I can remember, searching in 1Password for Android will turn up title and username matches as well as matches in the first line of secure notes. A few things that come to mind that might make your searches look a bit different would be:
* Sort by criteria. After tapping the search button you can tap Sort by... to set how your search results are listed (title, date created, and so on).
* A specific vault or account was selected for viewing. You can tap the vault symbol in the top left corner to select and view a specific vault or account. If you had a vault or account selected that had a smaller pool or item containing Posteo, the search might look different.
* Specific vaults or accounts were excluded from all vaults. From Settings > Vaults, you can exclude vaults from All Vaults. Similar to above, if vaults that contain more Posteo items were excluded your search could appear differently.

Would any of those be a possibility for you?
