PaperSurvey can process photos taken with mobile phones, making it possible to digitize surveys from virtually anywhere. However, photos taken with standard camera apps often produce recognition errors due to poor image quality, so choosing the right capture method matters.

Common Issues with Camera Photos

Regular camera apps are not optimized for document capture, which leads to:

• Skewed or distorted images from angled shots
• Motion blur from unstable hands
• Uneven lighting and shadows across the page
• Poor text contrast that reduces readability

These issues significantly reduce recognition accuracy and may cause processing failures.

Quick Capture Guide for Mobile Devices

Here is a simple guide you can share with colleagues on how to capture high-quality survey photos.

iOS (Built-in Document Scanner)

No additional apps needed:

1. Swipe down on the home screen
2. In the search bar, type "Scan Document"
3. Position your document and capture
4. Save the document and share it to @upload.papersurvey.io

Android (Google Drive)

Most devices have Google Drive pre-installed:

1. Open the Google Drive app
2. Tap the "+" button in the bottom right
3. Select "Scan" from the menu
4. Position your document and tap the capture button
5. Save the document and share it to @upload.papersurvey.io
