Test strip scan could not be completed
Last updated 18 days ago
Overview
If the app cannot properly read your test strip photo, you may see a warning asking you to scan again or manually confirm your water readings.
This can happen if:
The entire strip is not visible
Lighting conditions make colors difficult to read
The strip is blurry or partially blocked
The scan engine cannot confidently detect the results
The app will still let you manually adjust and confirm the readings so you can continue your water test.
How to fix the scan
Before scanning again, make sure:
The entire strip fits inside the on-screen frame
All color pads are fully visible
The image is sharp and not blurry
The strip is placed flat on a clean surface
There are no shadows or reflections on the strip
Scan again
If the scan was unsuccessful:
Tap Scan Again
Reposition the strip inside the guide
Hold your phone steady
Retake the photo
The app will attempt to analyze the strip again automatically.
Manually adjust the results
If the scan still does not look correct, you can manually adjust the detected values directly on the result screen.
Compare each detected color with:
Your physical test strip
The color chart printed on the test strip bottle
Select the color value that most closely matches your strip, then tap Confirm.
⚠️ Always verify the results before confirming. Lighting conditions and camera quality can sometimes affect color detection accuracy.
If the issue continues
If scanning repeatedly fails:
Clean your phone camera lens
Try a brighter environment
Avoid direct sunlight
Use a plain, light-colored background
Make sure the strip is scanned within the recommended reading time
You can always continue by entering or adjusting the readings manually.
