How to change storage location from ROM to SD card in a tablet?

Welcome to Blackview store, which offers Chinese tablets, Wifi only tablets, 2K display tablets, tablet with GPS, Widevine L1 tablets, etc. Hope this guide helps.

Moving apps, media, and files from internal ROM to an SD card can free space and improve performance on many tablets. This guide walks you through common steps, precautions, and options most users encounter when changing storage location settings on Android-based tablets.

Before you begin, check that your tablet supports external storage and that the SD card is compatible and formatted. Some tablets treat microSD as portable storage, while others allow it to be adopted as internal storage; this affects how apps and files behave after transfer.

Step-by-step checklist

Backup data: Back up photos, documents, and app data to cloud storage or a computer before changing storage settings.
Insert the SD card: Power off, insert the card, then power on the tablet.
Open Settings > Storage: See how the device recognizes the SD card.
Decide format: Choose “Use as portable” or “Format as internal” (adoptable). Portable keeps files portable; adoptable encrypts and integrates the card into internal storage but ties it to the tablet.
Move media: Use your Gallery or Files app to copy or move photos, videos, and music to the SD card.
Move apps (if allowed): Go to Settings > Apps > select an app > Storage > Change > SD card. Many system apps cannot be moved.
Use app settings: Some apps let you set their download or storage location directly (camera, podcast apps, downloaders).
Set defaults: Change default save locations for camera and downloads to the SD card when possible.
Check card speed: Slow cards can reduce app performance; use a high-speed, class-rated card for apps.
Unmount safely: Eject the card via Settings > Storage > Eject before removing to prevent corruption.

Troubleshooting tips

If the tablet fails to recognize the SD card, try reinserting it, testing it in another device, or formatting it in the tablet. If apps won’t move, your Android version or manufacturer may restrict transfers; consider clearing cache or uninstalling unused apps to free internal space.

Note: formatting as internal storage encrypts the card; removing it later without reformatting will make its contents inaccessible. Always keep backups before adopting a card as internal storage.

When to choose each option

Choose portable storage for flexibility to move the card between devices and to access files on a computer. Choose adoptable/internal storage when you need a larger effective internal capacity and accept that the card will be tied to that tablet.

Final checks: confirm photos, downloads, and newly installed apps save to the SD card and operate as expected. Review app permissions and storage locations after major changes.

By following these steps and precautions you can safely shift much of your tablet’s storage burden from ROM to an SD card, extending usable space and helping the device run smoothly. If you encounter persistent problems, consult your tablet manufacturer’s support documentation or a reputable repair service for assistance.
