Steps to reproduce the behavior:

1. Open ffem lite application ( Should be running on Alpha 0.30)
2. Go to the settings icon on the top right
3. Click on About
4. To unlock the diagnostic mode, tap on the version number (Alpha 0.30) continuously about 10 times
5. Once the diagnostic mode is on, go back to scanning the color card and use the manual capture button that the diagnostic mode provides

The application crashes.

Observed on:

• Redmi Note 6 Pro (Android, Version 9)
• Samsung - A260G (Android, Version 8.1.0)
• Moto G Play - (Android, 7.1.1)

The error only occurs on Diagnostic mode

The test for residual chlorine did not give any Euclidean value. 0 and 0.5 ppm was done for 3 phones which did not give any result. The pictures of which have been uploaded in the test file in the drive.

Certain phones (Lenovo K8 and Honor LND-AL30) seem to detect the barcode very unpredictably - even before it is fully present in the screen. the app then automatically crops the image, and invariably is unable to pick out the coloured swatches.

I have shared a video of this phenomenon on email, as I can't attach videos here.

1. Launch ffem Lite app from a ffem Collect survey question
2. Display result screen on completing the test in ffem Lite
3. Clicking Submit Result on result screen to close and return result to survey

Since yesterday (04/09/2019) I have been unable to push images to the server from all phones tried (5 different models, old and new both).

After the image capture, the status remains "In Outbox". Wi-Fi is working and apps are all updated to the latest released version.

Information to be displayed on result screen:

1. The title of the test (Fluoride)
2. The result value (1.5)
3. The result unit (mg/l)
4. Risk factor (ex. for Fluoride: Low [0 - 0.9], Medium [1 - 2.9] or High [3+])
5. Margin of error
6. Button: Submit Result

The app is giving bad lighting (with and without torch) and crashes most of the time on Asus Zenfone(ASUS_X008DA) and honor(LND-AL30) .
On Redmi Note 6 pro, the app does give results but crashes once in a while.

Errors while testing for residual chlorine

• With the new portrait mode, the error is always shown as "Bad Lighting" in Redmi Note 6 Pro and the image so received is sliced into half, images of which has been uploaded on the Test folder(Cl_RedmiNote6Pro_std_BadLighting).
  To be noted: The bar-code has never been detected by this phone and the capture button is being used while analyzing as of now.
  -The app is also continuously crashing once in a while on Samsung On5 and Redmi Note 6 pro.

App crashes during calibration of pH

To reproduce:

1. Launch ffem Lite app (Alpha 0.36)
2. Navigate to Settings
3. Select Calibrate
4. App sometimes crashes here

Note: If calibration works fine, then it shows 'Calibration error' for the test result

Devices
1, Redmi 4, Android OS 7.1.2
2. Samsung Galaxy M30s - Could not calibrate

Would it be possible to have barcodes, swatches and layouts outside the code? In a JSON / XML config file for example?

• Manual testing procedure
• Different types of testing
• Resources required
• Data to be collected
• Links and references to relevant documents

The application does not return any result on Asus_X008DA for Fluoride.
Two test images have been uploaded in the test images folder. (Fluoride_Asus_X008DA_No_result).

High Range Fluoride with concentrations from 0.5 - 5.5 (0.5, 1.5, 2.5, 3.5, 4.5, 5.5) mg/l to be added

To be able to focus the camera during the barcode scanning without losing focus to eliminate blur images.

1. The app crashes while using the 'Select existing image for analysis' update, in the following phones:   
   Samsung A2 
   Honor LND-AL30   
   Redmi Note 6 Pro   
   Samsung J2

2. 3/5 phones which did give results with this update took about 2-6 mins to do so, all of which were errors.

There have been repeated calibration errors in Redmi Note 6 Pro and some in Moto G. In Redmi Note 6 Pro, this error could be because of the initial chlorine alignment layout that is used to adjust the phone, which is not appearing anymore.

Steps to reproduce the behavior:

1. Go to ffem lite app
2. Click on the '+' button for a new test
3. See error

On Redmi Note 6 Pro, on clicking the '+' button a timed layout of the chlorine card is supposed to appear which aids in aligning the phone.

Screenshots
If applicable, add screenshots to help explain your problem.

Smartphone (please complete the following information):

• Device: Redmi Note 6 Pro
• OS: MIUI 11 based on Android 9.0
• Version: Android

Name: Residual Chlorine
Sample Type: Water
Unit: mg/l
Range: 0, 0.5, 1.0, 1.5, 2.0, 2.5
UUID: f1d64b11-64c4-4a34-806e-ad0d47bcc96b
Barcode: bcc96b

The swatch detection seems to be quite erratic, and tests are frequently giving errors as a result. this may be related to Issue #4 , but it's hard to say since it occurs on some phones that behave fine otherwise.

Some sample screenshots:
Moto G3:

Asus Zenfone 3:

Samsung A260G:

Honor LND-AL30:

The new update is crashing with Redmi Note 6 Pro, Asus_X008DA, SM-A260G and Moto G4.

Add a LaTeX user manual in English.

In order to try the FFEM Lite app in controlled light environments, it would be useful to have a flash on/off toggle control in settings so that flash can be used while the camera is in action, scanning and capturing images for analysis.

The app is no longer detecting the bar code for Asus Zenfone and Samsung G5 even after uninstalling and installing it again with the new update even though both seem to be running on the Alpha 0.20 version.
The format also does not align or detect for phones like honor AL30(display 5.99 inches) and Redmi Note 6 Pro(display 6.26 inches)
