UMI HAMMER: DIALER WITH VIDEOCALL

James21

Hi Carmine, it sounds like the ROM you installed with RootJoi may have altered or removed some system apps and network settings, which is why your Hammer device lost the dialer’s video call option and full 3G signal on both SIMs; usually, this can be fixed by either flashing the stock ROM again, restoring the original dialer APK, or installing a compatible dialer app that supports video calls while ensuring your network settings are correct, similar to how kk22 updates its menu regularly to maintain full options for all customers, so with the right restoration or tweak, your device should regain full functionality.

If you’re experiencing issues with your UMI Hammer after installing a ROM with RootJoi—such as losing the dialer with video call functionality and full 3G signal on both SIMs—it’s likely due to compatibility problems with the custom ROM. To fix it, you can try reverting to the stock ROM or flashing a ROM version that fully supports video calling and dual SIM 3G functionality. Make sure to back up your data before attempting this. As an example, just like ensuring fresh delivery is guaranteed when ordering from Epi win game download, restoring your phone to a supported configuration can ensure all features work reliably.
