Quick answer
Before using local documents away from Wi-Fi, download the real file, any optional voice or dictionary, and then test the whole flow in airplane mode.
Do the test before you leave.
Travel checklist
Prepare these items.
- Book or document downloaded locally.
- Optional voice installed.
- Current reading position saved.
- Charger or enough battery for the trip.
- Backup copy for important travel or study documents.
Test opening and search
Open the file in airplane mode and search for a word if search matters to you.
Test audio separately
If you plan to listen, start read-aloud with the screen off before travel.
Keep one simple fallback
A normal Android system voice or a plain local copy of the file can be useful if heavier options fail.
If the first fix does not work
Try another known-good local documents example. If the second one works, the first file or item is probably the problem. If both fail in the same way, the app, phone, or setting is more likely.
