    Yup, we are facing the same issue.

    It seems like a problem when network switches from 4g to 3g/2g , it is not able to latch onto anything and although it shows mobile network, but actually there is none.

    Hi, I'm having a problem, randomly I lose all signal, even go into settings and the signal strength is 0. It won't come back of its own accord, I have to turn airplane mode on and off for it to reconnect to the network. Has anyone else faced this issue please, as I'm getting worried? Any help would be insanely appreciated, thank you :)

    As aeroplane mode fixes it, I seriously doubt this is a hardware fault

    Just updated to OxygenOS 5.1.8 and it a still have the problem that I lose my network connection despite the display shows 3G or H+.
    It seems like this will not happen, if I deactivate Dual 4G Network support in SIM Settings (don't know how this option is called in english, as I am using a different language).

    OxygenOS 5.1.8 same problem. Network stuck, H+ showing. Helps only switch mobile data, reboot, airplane. Put the same sim in 3T, never facing this issue. Please fix it. Oneplus 6 is useless.

    after upgrading to 5.1.8 I am facing the same issue on Vodafone. It keeps losing 4g network, though 4g is available superb in my area

    My friend has the same issue on his OP6.
    I had OP5 with the same issue, but OP didn't fix it for 10 months. I think it's the hardware problem.
    Had to switch to another phone. I wanted to purchase op6, but couldn't, because of such feedbacks.
    Belarus, carrier Velcom. They don't have LTE, just h+.

    Still no resolution for this after the OS update? An absolute joke it's not been resolved.
