There is nothing more exciting than unboxing a new Samsung Galaxy, but that excitement quickly turns into frustration when Smart Switch tells you: “Failed to transfer messages.” We have all been there, staring at that progress bar that just won’t move.
I have spent years troubleshooting Android migration issues, and usually, the problem isn’t your phone—it’s a simple setting or a minor sync glitch. Here is my proven checklist to fix this error and get your memories moved to your new device:
- 1. The “Cable First” Rule: While wireless transfer is convenient, it is prone to packet loss. If it fails, use a USB-C to USB-C cable. It is 100% more stable for large message databases.
- 2. Grant “Full Access” Permissions: On both devices, go to Settings > Apps > Smart Switch > Permissions. Make sure “SMS” and “Files” are allowed. Sometimes a recent system update resets these permissions.
- 3. Update the App on BOTH Phones: If the version on your old phone is even slightly older than the one on the new phone, the handshake will fail. Check the Galaxy Store/Play Store now.
- 4. Disable “Message Encryption”: If you use advanced messaging features (RCS) or apps like Signal, turn them off temporarily. Standard tools often struggle to read encrypted databases.
- 5. Clear the Cache “Ghost”: Go to Settings > Apps > Smart Switch > Storage and tap “Clear Cache”. Do this on both devices to remove any temporary corrupted files.
EXPERT TIP: “If you are still stuck at 99% or getting a ‘Failed’ message, try turning off Airplane Mode on and off. This forces the wireless antennas to reset their handshake protocol, which often clears the ‘jam’ in the data stream.” — Master Yavas.
Don’t give up! If these steps fail, it might be time to look at Dr.Fone – Phone Transfer that can extract your SMS database directly.
