[BUG] Duplicate images on iOS are sorted differently from ios "Photos" app

[iosephmagno]

Describe the bug Sometime users duplicate images in their albums (eg. to apply different effects to the same pic). Noticed that all duplicated images are not loaded by photomanager.

To Reproduce Steps to reproduce the behavior:

1. Load Recents album via photomanager
2. Duplicate an image via native photos app
3. Load album again via photomanager and see that duplicated image is neglected

Tested on iOS, it might affect android as well.

Expected behavior Albums in photomanager should be an exact copy of what they are in native photos app.

Flutter version

Smartphone (please complete the following information):

• Device: iPhoneXS
• OS: iOS17.7.1

Could you tell me how to get an iOS 17 device? I'm really curious about it.

[iosephmagno]

Typo :) It’s 14.7.1

[AlexV525]

Versions, code snippets, screenshots/screenrecordings, and whether you've granted full permissions or not.

[iosephmagno]

How to reproduce issue on iphone XS, iOS 14.7.1, full permissions enabled, video/photos available below:

1. Open wechat assets picker
2. Load recents album
3. Switch to iOS photos and duplicate a photo (not the last one)
4. Switch back to wechat assets picker
5. Load recents album
6. Duplicate photo in point 3 is ignored in the picker’s grid.

Photos:	---	---	---	---	---

Noticed by chance that duplicate photo is not ignored, it is instead placed in the wrong place (see pic below, red “X” mark vs “check mark”). Check mark is the right chronological position (as in iOS photos app). This means there is a problem with duplicate photos’ timestamp. Not sure whether it depends on iOS or photomanager.

[AlexV525]

Can you verify if the #606 solve your problem?

[iosephmagno]

Will verify soon and let you know. Since then I also discovered that pics transferred via airplay (eg. from macbook to iphone) seem to be ignored by photomanager. Not sure if it is linked to sorting, will open a separate issue.

[AlexV525]

See the description in #620 for the detailed behavior about the "Photos" app.

[iosephmagno]

Tried with last version of wechat asset picker and this problem is still there, same as described above.

[iosephmagno]

A duplicate pic is placed soon after origin pic instead of being displayed as the most recent pic in the gallery. See pic below.

[AlexV525]

The photo gallery placed the duplicate photo at the most recent place? What if you completely kill the photo app and check again?

[iosephmagno]

I’m not sure I get what you mean. Iphone’s photo gallery places it at most recent place. This is common behaviour: user might duplicate some very old pics with the goal of having them at hand in most recent places (or maybe edit them). Wechat picker gallery places it soon after the origin one (as pic above) even after kill/restart

[iosephmagno]

This is same gallery from iphone app. Duplicate pic is at most recent place. Origin pic is not visible (it is up in the grid).

[AlexV525]

Sure. I just want to confirm if the "Photos" app will keep these positions after it's been kill/restart, since last time photos that have been airdropped are re-positioned after the "Photos" app restart.

[AlexV525]

So we use the creationDate key as the default sort condition on iOS, which means duplicate photos might have the same creation date from the system, but gallery handles them differently.

[iosephmagno]

Maybe that was a temporarily bug from ios. Iphone’s photos stores new pics at most recent position (airdropped files included) and doesn’t change sorting after kill/restart.

[iosephmagno]

@AlexV525 any updates on this?

[AlexV525]

@AlexV525 any updates on this?

Sorry that I'm personally busying in preparing for the DevFest next month, and these issues are all scheduled for further investigations.

[iosephmagno]

Thx for letting me know it. I will ping you again later on

[iosephmagno]

Hi Alex, any news on this?

[iosephmagno]

@AlexV525 @moyusword same issue occurs with airdropped files. If we send files over aidrop they don’t get placed as most recent in the Recents album’s grid. Also, airdropped videos aren’t listed at all in Recents album, they only appear in Video album.

Tested on both ios 14 and 15. Bug is reproducible on wechat assets picker.

[AlexV525]

If you're indicating airdropped files too, I'm pretty sure it's the same issue that #620 is trying to fix, which is typically an iOS bug when new files are dropped and not following the creation date sort.

Closing as it seems to be resolved already, or cannot be solved until iOS fix this.

[iosephmagno]

I have read #620. Here are the differences I notice: 1) 620 says photos are positioned well when app is open yet and repositioned wrongly after it closes. We don’t experience this with Duplicate photos (they are positioned wrongly in both cases). 2) Airdropped videos are not placed in Recents album, either when app is open or after it is closed.

If you guys converge all ios sorting issues in #620, please check these differences.

[AlexV525]

I'll leave this open until we get more responses from iOS developers.

[AlexV525]

Also please file a separate issue for videos.

[AlexV525]

Please verify if #659 solves this problem.

[iosephmagno]

We will check soon and let you know here. Thx!

[iosephmagno]

Hi @AlexV525, we tested #659 and it doesn't fix this issue on iOS. Duplicate photos are still placed soon after original ones, and not as most recent ones in Recent's album grid

[AlexV525]

Can you make a screenrecord with the whole process?

[iosephmagno]

Checking this again. A team mate tested with an old iphone

[iosephmagno]

Is this fix also available in 1.3.10?

[AlexV525]

Is this fix also available in 1.3.10?

Of course not...It's available through direct dependency or the 2.0.0-dev.1 version.

[iosephmagno]

Bug is fixed in 2.0.0 👍
