Google Play version 24.0.3 is installed as generic build, breaking Firebase push notifications

[ralfrupf1976]

Steps to reproduce

1. Install Nextcloud Talk 24.0.2 from Google Play on a Samsung Galaxy S10 Lite (SM-G770F, Android API 33).

2. Log in to a Nextcloud server and verify push notifications.

3. With Talk 24.0.2, diagnostics report:

   • Build flavor: gplay
   • Google Play services: available
   • Firebase push token: present
   • Push registration at server: successful
   • Push registration at push proxy: successful
   • Push notifications work.

4. Update Nextcloud Talk through Google Play to version 24.0.3.

5. Reboot the phone and open Talk diagnostics.

6. Diagnostics now report:

   • Build flavor: generic
   • Google Play services: not available
   • UnifiedPush services: 0
   • No Firebase push token

7. Send a Talk message to the account while the app is closed.

8. No push notification is received.

The issue was independently reproduced on a second device:

Samsung Galaxy S25 FE (SM-S731B, Android API 36)

• The phone is new and Nextcloud Talk had never previously been installed.
• Talk 24.0.3 was freshly installed directly from Google Play.
• Diagnostics immediately reported Build flavor: generic and Google Play services are not available.
• Push notifications did not work.

As a reverse A/B test, Talk 24.0.3 was removed from the S25 FE and Talk 24.0.2 gplay was installed.

Push notifications immediately worked again.

No server-side configuration was changed during any of these tests.

Expected behaviour

The version of Nextcloud Talk distributed through Google Play should use the gplay build flavor, detect Google Play services, register a Firebase push token and receive push notifications.

Updating Nextcloud Talk from 24.0.2 to 24.0.3 through Google Play should not change the app from gplay to generic or disable Firebase push notifications.

Actual behaviour

After updating Nextcloud Talk from 24.0.2 to 24.0.3 through Google Play, the app identifies itself as:

• Build flavor: generic
• Google Play services: Google Play services are not available
• UnifiedPush services: 0 services available
• Offer UnifiedPush: No
• Use UnifiedPush: No

No Firebase push token is generated and push notifications stop working.

The behaviour was reproduced on two different Samsung devices and Android versions:

Samsung Galaxy S10 Lite (SM-G770F, Android API 33)

Before Google Play update:

• Talk 24.0.2
• Build flavor: gplay
• Google Play services: available
• Firebase push token: present
• Push registration at server: successful
• Push registration at push proxy: successful
• Push notifications: working

After updating through Google Play:

• Talk 24.0.3
• Build flavor: generic
• Google Play services: not available
• No Firebase push token
• Push notifications: not working

Samsung Galaxy S25 FE (SM-S731B, Android API 36)

Fresh installation directly from Google Play:

• Talk 24.0.3
• Build flavor: generic
• Google Play services: not available
• No Firebase push token
• Push notifications: not working

After removing 24.0.3 and installing Talk 24.0.2 gplay on the same S25 FE:

• Google Play services are available
• Firebase push works again
• Push notifications work again

Additional iOS control case

An iPhone connected to the same Nextcloud server/account continues to receive push notifications normally.

Nextcloud Talk for iOS is still on version 24.0.2; no 24.0.3 iOS update has been installed on this device.

This gives us the following A/B results:

• Android Talk 24.0.2 gplay → push works
• Android Talk 24.0.3 from Google Play, reported as generic → push fails
• Android downgrade from 24.0.3 to 24.0.2 gplay → push works again
• iOS Talk 24.0.2 → push continues to work

Server environment

• Nextcloud Server: 34.0.3
• Nextcloud Talk server app: 24.0.4
• Notifications app: installed
• Signaling mode: External
• Server supports WebPush: No

The server configuration remained unchanged throughout all tests.

Hello,

I can confirm that notifications do not work on any Android devices (Xiaomi, Poco, etc.) running version 24.03.

However, they do work on the Windows app.

I am receiving the notification on my Windows PC, but not on my Android devices running version 24.03.

bonjour,

Je confirme que les notifications ne fonctionnent sur aucun appareils android (xiaomi, poco....) avec la version 24.03.
Cependant elle fonctionnent sur l'application windows.

Je reçois bien la notification sur mon pc windows mais pas sur mes appareils android qui ont la version 24.03.

Quick update from my side:

I tested 25.0.0 RC2 (gplay) on the same Samsung device and it works correctly.

Installation and account login completed without any issues. Google Play Services are detected again, the push notification test is available, and the test notification was delivered successfully.

So on the same device:

• 24.0.3 (Play Store / generic): no push notifications
• 24.0.2 (gplay): account login could not be completed
• 25.0.0 RC2 (gplay): login works and push notifications work correctly

For now, 25.0.0 RC2 gplay seems to be a working solution for me.

Looks like the issue is only wrong version published in Google Play. If you install v.24.0.3-gplay from the APK from the release channel here, everything looks good:
https://github.com/nextcloud/talk-android/releases/download/v24.0.3/gplay-nextcloud-talk-24.0.3.apk

I think this shlould get a bit more attention @mahibi

[whiteonred]

Confirmed, Galaxy S25 Ultra

[NoelleAttachedStorage]

OnePlus 9 on LineageOS with play services enabled, same issue. For the time being I've been using the nextcloud services app from f-droid and united push from the community apps.
