Android - Scanned Photo Showing Blank/Gray

The problem you're encountering, where the scanned photo appears gray, is typically due to the photo not being properly detected by the scanner. This can often be resolved by ensuring that the scanner's detection feature, represented by blue lines, fully recognizes the photo before proceeding with the scan.

Here's a sample screenshot:

Here are the steps to follow:

1. Place the photo you wish to scan on the table.
2. Ensure that the area/surrounding is well-lit. This helps the scanner to detect the photo better.
3. Wait for the blue lines to appear and fully encompass the photo. This indicates that the scanner has detected the photo. 
4. Once the photo is detected, proceed with the scanning process.
