This is intended game design. Pillager patrols spawn randomly 24-48 blocks away from the player.

This issue is similar to MCPE-54465 but on Android devices.
Can confirm this has been happening for Galaxy J7(J700H) running Android 6.0.1.
Crash happens sooner after opening the app or while loading into the main menu.
Doesn't affect the PC version tho.
Does this happen to old villagers or new villagers(experimental gameplay enable)?
This bug is fixed on recent beta version.
This is resolved in beta 1.11.0.1.
Only happens when Experimental gameplay is enabled.
Also, they make angry noises when stared at them directly on creative mode. Confirmed on beta 1.11.0.1
Duplicates MCPE-40012
Do you mean while holding a locator map, the player pointer goes all around the map?
Can you explain it in more detail? Also you can add screenshot or video on the bug.
