    Why it still in review for 2017 LTS? why it is not available in latest version 2017.4.37 ?

    The fix worked for me!
    64bit apk built with Unity 2019.2.18 now runs smoothly again on our S7.

    No idea. Since this is a copy-paste from a bug report, and Unity encourages you to attach a project to said report, it is likely that the project is not publicly available.

    From the release notes of 2019.2.18f:
    "* Android: Fixed a physics performance issue on ARM64 on certain devices with power mode disabled. (1186295)"
    Will test it on our problem device (Galaxy S7) soon.

    Some of our users have also reported super laggy frame rates and we have confirmed that their devices are in the list, so we are also receiving lashback because of this issue.

    @Unity -- Please fix this ASAP and release an updated engine right away.

    Thanks in advance.

    Having the same issue. Getting lots of negative reviews in Google Play store.

    Why is this marked as "Fixed in 2019.3"? Reading through the 2019.3 patch logs it is listed under "Known issues".

    Still no solution for this very critical bug? We are getting lots of negative reviews on Google Play from people with these devices... Some people asking for refunds after the update and so on...

    il2cpp seems to be not stable at all, we cannot rely on it... Mono 32-bit does not have this problem. Unfortunately most people don't like the idea of manually installing a game apk and obb to avoid it, and we cannot reach all the user base to ask for them to use the 32 bit that we provide.

    Since Unity is one of the most popular game engines ever, IMHO they should talk more with Google before forcing us to use a "beta-bugged" feature like this :( Google could wait a little bit more for il2cpp to be considered stable before forcing everybody switching to it.

    Otherwise we are completely stuck, we just cannot update or launch our games for Android.
