FoneGeek Data Recovery utilizes read-only mode, which will only scan and recover your lost data. It has no ability to write and edit your files.
It depends on whether the data has been overwritten or not. The longer time it has been deleted, the less possibility to recover.
FoneGeek allows you to recover lost data in 3 simple steps: Select the Location > Scan the Location > Preview & Recover Deleted Files.
If you are unable to find the files you were looking for after a quick scan, you can try the "Deep Scan" to search for deleted files deeply.
It depends. Usually, FoneGeek only takes a few minutes to scan and recover your files. If you want to recover from device with large amount of data stored, more time are needed.
