    A few days after upgrading my OnePlus 7 Pro to Android 11 , it seems like my Widevine security level went down to L3, because I can't watch HD content anymore on Prime Video, Netflix, etc. This seems like a common problem, as there are other users reporting it:




    Does anyone know if this is something that is being addressed, and if so, when it's expected to be fixed?

    Thanks, @Liehjan, your solution worked. My Widevine Level is back to L1, but I'm not sure if it'll stay like that, as the problem manifested itself about a week after updating, so we'll have to wait and see.

    These are the instructions I followed (this didn't wipe any data by the way):
    ▪️ On my computer I downloaded the latest stable build, (currently, from here. It'll be different if you have a different phone; choose the correct one for your phone here.

    ▪️ Then I plugged in my phone to my computer and transferred the .ZIP straight into Internal Storage.

    ▪️Then I went to Settings > System > System Updates > Click the little settings icon on the top right > Local Upgrade.

    ▪️Then I clicked the file shown there, and clicked Install, then when it was done, clicked Reboot.

    ▪️After it rebooted, I checked the Widevine Level with the DRM Info App, and it was back to L1:

    Note: As @pconleynms mentioned, you might also have to clear the storage/cache on Netflix for it to work again as normal. I did not have to clear the cache on Prime Video though, but I did have to enable the Hardware Acceleration feature in Prime Video's settings for it to work again as normal.

    Try to flash the same build you are on again.

    It's now been more than 20 days or so since I first encountered the problem and I have yet to find a fix. I have tried all the possible solutions and none seem to work. It's really disappointing that this hasn't been fixed yet considering many people are having it.

    For sure. If it doesn't, I guess I can re-flash it in about 10 minutes, since I already have the installer file downloaded. It's a pain, but I guess you gotta work with what you have.

    I've encountered the same problem on 7t pro; and have the required rom (11.0.2 HD01AA, in my case) ready in the local upgrade path.

    Is doing this 100% safe in terms of data integrity?

    FYI, I've already wiped the app cache/storage, even recovery mode - wipe cache option without success.

    Many thanks

    I did not lose any data anywhere (it told me I should backup my data, but that doesn't mean it'll wipe anything). It's basically like installing a system update when you get a notification that one is available, except you're doing it manually.

    If you have installed beta updates before, though, and you are going to stable ones, then I think it'll wipe the device, but beta updates have to be installed manually, so you'd know if you did that.

    Basically, if you're (and you should be) installing the exact same version update that you already have installed, you should be fine:

    What do you need to do when its installed on your phone? My phone only gives an option to restart it, but that doesnt work... What do you need to do after it is fully loaded in detail?

    I mean...you could restart it manually also. If the restart button doesn't work in the system update widget, then restarting manually would be the same thing.

    Hello! Is it still L1? Or did it revert back to L3?
