Profiling PostLateUpdate.FinishFrameRendering Causes Major Spikes in Performance for Android Game

I've been having issues lately on running my game for mid-range phones. It runs pretty smooth on my pocophone f1 but laggy on other phones. Looking at the game carefully it really doesn't have much details to make it lag. In terms of scripts I have really basic scripts that really don't run on Update(). Here is a shot of the profiler where I see that majority of the lag comes from "Profiling PostLateUpdate.FinishFrameRendering ". I'm pretty new to unity so I would appreciate all the help I could get. Thanks in advance!
