    Issues with update on Oneplus 6 OS11.1.1.1

    1. I uses internet on SIM-1 and send SMS via SIM-2.

    Whenever send SMS via SIM-2, 4G internet stops on SIM-1, then SMS is sent, then 4G is resumed.

    It is stopping internet on SIM-1 then sending SMS via SIM-2. Due to this issue I am unable to register on any UPI application because my registered number is SIM-2 and internet works on SIM-1.

    Whenever SMS is sent via SIM-2, mobile stops 4G on SIM-1, then UPI app shows unable to verify mobile number because of interruption of this internet.

    2. Notification Tone not ringing whenever any message comes. Not ringing in SMS/ Telegram/Whatsapp messages.
    3. E-mail notification not showing. Every time I have to open the Gmail app.
    Sometimes even Whatsapp message notifications are not shown.
    4. Screen is active even when it is locked. When I double tap on the screen it wakes up. How do I turn this off?

    Take an extensive backup of current OS
    try oneplus switch also.
    After backup -
    Install an app keepdata
    Run keepdata.
    Search for A10 downgrade rom from the A11beta 1 thread.
    Do as instructed.
    Yes A11 is as you say it is.. these are all known issues.

    I have exactly the same problem on my OP6. After OOS11, i lose internet connection on my home wifi (Deco mesh) whenever the Phone switches between nodes. It always worked before, and all other devices we have works. It is very annoying, because you don't always notice that it happens until maybe an hour later, then you have to turn off and on your wifi, and all of a sudden all my missed whatsapp-messages rolls in. As it is now, the phone is practically unusable at home, if I don't turn off wifi entirely, which isn't exactly feasible.

    I have tried clearing my cache, I have reset all connections, I have turned in developer mode and fiddled with the network settings, and also changed to a fixed ip. Nothing works.

    WiFi is now very unstable, locking up all the time when trying to turn WiFi off and on.
    Trying to turn on Flight mode just locks up the phone completely have to reboot by holding down the power button.
    Wishing I did not update. 😟 First time OnePlus did an update that made me want to ditch OnePlus. This must be fixed with an update before EOL. Have not tried a factory reset yet and don't really want to.

    Video of the fault

    I hope we can get to the bottom of this and get it fixed.

    I upgraded my one plus 6 and now my phone runs like crap. Slow between apps and Kakaotalk types in slowmo. Keyboard does not pop up on occasions on different apps, camera takes forever to load. Battery does not last as long.

    Phone used to feel rock solid before but now I feel like I have throttled iPhone with outdated iOS.

    I was getting ready to upgrade into another OnePlus device but I am seriously reconsidering into another brand because of how horrendous this upgrade is.

    Seems like OnePlus seriously have lost its core and original philosophy.

    Hi, all information regarding rollback can be found in the following thread.


    Although, since a rollback will involve wiping your device, it might be worth backing up your device and trying a factory reset first 🙂

    Ich würde vorschlagen, die Netzwerk-einstellungen, über die Option zum Sichern und Zurücksetzen zurückzusetzen. Sehen Sie bitte, ob es helfen dir kann. 🙂
    Nicht Alles zurück setzen.

    It won't happen, you would have to live with it or downgrading is the only option.

    I love the update other than I can't use my phone for anything I use to as I cannot give any apps permanent permissions. I need to either have the mic in use without having a headset plugged in and the phone locked but the new update won't let me give the permissions even with developer mode on. Other then that I cannot stop the phone from telling me when an app is using the camera for example but I know that the app is using it because I chose to use it for that. I understand that this is for "security reasons" but I'm not stupid. Is there any way I can fix these problems?

    Had really bad performance after upgrade, clearing Google Play Services app storage resolved the issue

    Check whether clearing cache and data of Google play services turns ok.
    Also update the results of experiment :)
