Bug Reports
1

REPRODUCIBILITY: 100%
OS VERSION: 5.0.0.67
HARDWARE: C2
UI LANGUAGE: English
REGRESSION: Cannot confirm or deny.

DESCRIPTION:

Android applications lose network connectivity when both SIM cards are enabled.
Connectivity is restored when one SIM is deactivated.

PRECONDITIONS:

Use and enable two SIM cards (both active in Settings > SIM cards).

STEPS TO REPRODUCE:

  1. Insert two SIM cards into the device.
  2. Enable both SIM cards under Settings > SIM cards.
  3. Launch any Android application that uses the internet (e.g., Aurora Strore, YouTube).
  4. Observe that the app cannot connect to the internet.

EXPECTED RESULT:

Android apps should be able to connect to the internet while both SIMs are enabled.

ACTUAL RESULT:

Android apps cannot connect to the internet when both SIMs are active. Disabling one SIM resolves the issue.

I noticed that WhatsApp is for some reason working and I can send messages.
I installed it from Aurora store.

MODIFICATIONS:

No custom modifications, patches.

ADDITIONAL INFORMATION:

I’m happy to provide logs or other diagnostic data upon request. Please advise what would be useful.

I have both SIM Cards enabled on my C2 with 5.0.0.67 and I don’t have this problem…
