Controller lag

Samsung Galaxy J3 Prime
At random intervals, bluetooth controls will randomly lock up/stop working for a short period of tine. This doesn't matter if it's a button or analog inout
The issue is *not*caused by lag, as even when running at 60 fps in a cave, it still occurs
Not a problem with the device as other apps that are compatible with bluetooth control don't lock up (asphault 8, ePSXe, etc)
Somewhat serious issue for controller users.
