The 5G is not working as intended. Once after I on the 5G network, I am no longer able to make calls. When I tried to make calls, it will just stuck at calling but no tones.

I will have to off the 5G, restart my mobile before my phone can work again to make calls. Had tried between on/off between version previously and now. It's still having the same issues.


  • @wayne.hbw Which carrier are you using? Do you have 2 SIM cards or just one?

  • I'm form Singapore. Using Starhub. Using 1 SIM card only.

  • @wayne.hbw I'll send you with instructions on how to log your device so that your developers can take a closer look at what's causing this.

     5G band Network does not work. "Dual-Band" wifi option is available. But 5G band Network is not showing.

  • Lol. For 5G network to work, you need to have 5G services in your area. And I'm damn sure that Bangladesh doesn't have 5G services.

  • As far as I can tell, 5G has not yet been deployed in Bangladesh, only that the BTRC is hoping to make it available this year.

    "Dual-band Wi-Fi" is not connected to 5G, but rather 2,4 and 5 GHz frequencies when connecting to a Wi-Fi network.

    Hey wayne, did you sign up for Starhub 5G plan, you need to sign up the 5G mobile plan+.

    I checked starhub 5G FAQ, while the phone is 5G ready, should Starhub not offer to your phone number, then you are unable to get 5G. Same for me with Singtel.

  • Hi Wayne,

    you got to sign up Starhub Mobile+

    and the device must be listed by Starhub to use 5g.

  • Yes. I'm on 5G mobile plan already.. the phone is able to connect to 5G. The thing I see is, when using only 4G, when phone calls comes in, the band will change to H+ for calls. But when I switch on the 5G band, it will switch to 5G band. But after a short while. It will fix to either 5G/4G. It won't change to H+ for either call in or out. I will need to off the 5G and restart my phone on order to have my calling works again.

  • oh understand better now.

    Then sounds like the antenna/software internally.

    Got to do the log way then! happy CNY in advance too!
