After dealing with a corrupted Micro-SD-card and almost losing a lot of valuable (at least for me) recorded tracks, I have one request:
The ability to make automatic backups to one or more of the major cloud services like Google Drive and Dropbox. This will also protect your valuable data when your phone gets stolen or is lost.
I think all the major cloud-providers have an Android-sdk or API so including them should not be so difficult.
By the way, I managed to recover my tracks from the SD-card by making an image of the drive, extracting all NMEA-sentences (no files could be found, so I had Matlab search through the whole 16GB of data) and from that reconstructing gpx-files which could be imported into Locus again. But, a backup on Dropbox would have saved me this task.
