When I play on Minecraft servers like CubeCraft or in my world, I experience a sharp drop in frames and screen freezes for 10 seconds at random times during playing, and sometimes the game crashes, knowing that my device is of the middle class and is good for running many games. Also, this drop in frames during playing is accompanied by sometimes the control buttons (Experimental control) return to their original size and original places (they reset themselves) during playing.after this i complete the game normaly or sometimes the game crashes after this, and this causes great annoyance during the game.
Note: sometimes the buttons of the (Experimental control) reset themselves without screen freezes or fps drop. My Android version is Android 13, my Minecraft version is 1.21.2 and this problem happend to me one time only in my world But it happens to me a lot on Minecraft servers.
