    Unity 2022 is already LTS but this regression dont allow to update over Unity 2021.3.19f1

    input in game totally broken on android. Do Unity have plans to fix it in Fresh LTS UNITY and maybe backport fix to Current stable LTS 2021?

    I am currently looking at this issue but I might need some more context.

    Correct me if I am wrong, but I have seen you reporting here that this frame skipping is happening in other platforms as well, and not only on Android. Is this still the case?

    However, it some reports pointed out that the issue appeared after UUM-10244, but this is an only Android fix. It shouldn't affect other platforms.

    Do you have reproduction steps for the editor?

    In Editor I can reproduce this bug easily because my Notebook has touch screen.
    Then same steps like for any phone.
    Higher target fps - more skips :)

    There was just thoughts that it is core of issue :) But may be it just make issue more visible on Android :)
    may be completely unrelated :)

    Hi @manugil

    Do you have some news about jittering issue fix progression?

    We relly want to upgrade to Unity 2022 and to 2023 but stick to 2021.3.19 because of this bug :(

    This is happening on almost all Android devices. EnhancedTouch is randomly reporting (0, 0) touch deltas very frequently. I haven't found a proper fix for it yet. In some devices setting targetFramerate to highest supported refresh rate fixes it, but that's not a solution we want. Enabling Optimised frame pacing is also fixing this issue partially on some devices, but optimised frame pacing itself is causing more issues, so we can't rely on that.
    Even scroll rects are jittering if you move them slowly on Android.

    This issue doesn't seem to exist on iOS devices.
