    I'm still on 3.12 due to havoc os 4 being labeled as beta still.
    Anyway I just tested tested out some different values for dalvik vm in build.prop

    These are the current AOSP defaults for devices with 6gb of RAM

    Havoc OS uses:
    dalvik.vm.heaptargetutilization 0.75
    dalvik.vm.heapminfree 4m
    dalvik.vm.heapmaxfree 8m

    AOSP uses:
    dalvik.vm.heaptargetutilization 0.5
    dalvik.vm.heapminfree 8m
    dalvik.vm.heapmaxfree 32m

    the other 3 values are the same

    of course there are Oneplus 3 devices with less RAM, but my 3T has 6GB RAM so I gave them a test and I feel like they improved performance on my device :)

    My guess why they improve performance:
    it might not be as efficient since the heap can be up to 50% larger than necessary but the vm doesn't have to increase/decrease heap size as often.
    Also the VM doesn't have to free RAM as often to have exactly 4-8m free.

    Other ROMs have 2-8m or 8-16m but there is more memory to play with than just 4m

    heapminfree/heapmaxfree is used to avoid kernel calls afaik and therefore delay (reduce latency).

    Values for havoc OS in the github repo seem to differ again, but in a different way:
    I would prefer 16m heapstartsize still
    Havoc 4.x is not beta for long time. Latest is 4.4 or 4.3 depends from device...However some device might be drop out from further development...Check it for Havoc-OS website or Telegram group for latest version for your device.

      See if you that gesture activated. Possibly it is because of that
      Thank you for your reply. I checked it out but couldn't find anything related to flashlight. Lately it hasn't turned on so often, so it's not really bothering anymore.
