Volla x23 error camera app, wrong gps metadata

Charly · 18 Nov 2023, 10:56

Hello, I have a volla x23 cell phone. I use ut 20.04 as the only os in rc version 7 which according to my information corresponds to the current ota-3 .
The GPS information stored in the metadata of the photos appears to be incorrect.

Although they are in the right country, they are roughly 100 km too far north .

However, the Gps function is correct in unav. It is only about the metadata of the photos. So it's a problem with the photo app.

To test this, I took a photo of an object whose position I know exactly. I used mat2 to read out the gps data in gms format. Then I converted it to dd format and specified it as the destination in unav.
I hope I can contribute to further improving the software quality of ut with this error message.

Greetings Charly

Addition Infos:

Describe the bug:
If you take a picture with a volla X23 with lokation position enabled the photo app store the wrong gps metadata in the picture.

Steps to reproduce the bug:
Take a picture with the UT Photo app with gps location enabled, read the included metadata with mat2 -s. Check the gps position of the metadata and compare it with the gps position where you took the photo. You will find an difference of 50 to 100 km.

Expected behaviour:
Please check this behavior and correct the photo app to store the right gps metadata in the pictures.

Additional context:
I took a picture at: 52° 40' 12.4" N 13° 19' 0.8" E
With mat2 -s its shown 53° 20' 12.12" N 13° 36' 58.66" E
(If you need, i can send you this picture)

This is a known bug. I also already proposed a fix, but that has not yet been reviewed, merged and released.

So I can only ask for patience, unless you can build the app for yourself from the branch of my MR.

Great, I'm waiting for the correction. Is there a chance that it will come with ota-4?

How do I find out if a fault is already known?

@Charly I hope the fix will land soon, but I guess I will need to ping some people to check it. Then it will be released either with a new release of camera app or the next OTA. Fingers crossed.

You can find out about existing bugs in the corresponding bug tracker. All apps should give links on their OpenStore page. All core apps "live" here: https://gitlab.com/ubports/development/apps. If the issue involves a core component, not an app, you can look at the issues in the core repositories here: https://gitlab.com/ubports/development/core.
