I've been experiencing a lot of stuttering recently, so had a look at the frame rates as I was playing.
This is what the support page has to say:

Now I'm not very techy so I don't know if im missing something, but my understanding is the frame cap is 30fps unless your phone is good enough in which case it might not be capped.
And yet I seem to be experiencing this frame cap only sometimes. When I haven't touched the screen for a while, the game sits at 30fps:

(See the red number at the top)
However when I touch the screen, the frame rate momentarily jumps up to my phone's default refresh rate of 144fps:

The constant jumping between frame rates seems to be a source of this stuttering, and since it triggers when I touch the screen, parrying and dexing are made especially difficult.
Is this weird? Feels weird.
Would appreciate any insight from anyone. Thanks.
