Swipe inertia or friction has become excessive recently
A month or so ago, I noticed that it had become much harder to close an app by swiping it up and throwing it off the upper edge of the screen. It's as though the friction in the Newtonian physics model increased massively across some update. I've tried increasing/decreasing touch sensitivity. Nothing I try seems to work. It's so bad that I literally can't close apps sometimes (but weirdly, only sometimes) unless I clear their storage or restart. I'm not even using a screen protector, so this shouldn't be a touch issue.
Thanks for confirming as upstream. Definitely it's real. Happens everyday, but frustratingly with no rhyme or reason. Empirically seems like maybe changing partitions increases the probability of it happening. That could make sense because it would cause temporary latency spikes due to cache thrashing, which in theory could interfere with friction modeling. Then again, it can persist for minutes on end, and maybe longer. Then suddenly everything is fine. Bizarre!
This has been happening less frequently but maybe that's just measurement error on my part. It sort of fixes itself randomly too, after minutes or hours (or due to a profile switch?). I've tried all the obvious things like cleaning the screen and making sure I'm not touching another part of the screen by mistake.
@thestinger Please forward this upstream or point the relevant devs to this comment, as this bug is extremely hard to reproduce. I've learned that:
-
It doesn't seem to have anything to do with the light sensor (and as stated above, it's not an accidental screen touch or debris issue).
-
Locking and unlocking the phone seems to instantly restore normal friction.
