Hi @Danyboy20! Check that your software is up to date by going to Settings > Software update > Download and install.

After downloading the latest software update, my S21 android phone's cursor kept jumping around. It totally frustrated me. I finally set my keyboard to Italian language and it doesn't jump around anymore. The Italian keyboard is similar to the English keyboard. Wow what an easy fix!!

Did you find a fix? Exact same is happening to me.

Try this:

Under Settings > General Management > Samsung Keyboard settings (on top, it will read Samsung Keyboard) >  Reset to default settings > Reset keyboard settings

This took care of my A52 5G during the second last install.  Now, January 23, 2023, I got another install and the same story repeated. I know, this is very frustrating and annoying.   Now, if you think positive, you just found the solution to this and also likely to your emojis not showing up when they should.  Have a blessed day and see if you can help someone else with this knowledge.  I hope this does not create any issues with your already existing settings.  I suppose this may be an insignificant price to pay in the name of sanity.

Hi, this fix for the page jumping when editing, deleting or adding text took me ages to identify but I have managed to sort the issue on my S23 so hopefully this will help someone else. The problem is that the Samsung supported writing assistant, usually Grammarly is the bug that's causing the issue. This is how I fixed mine;
Settings
Language and keyboard
Select 3rd party content to use
Switch off Grammarly writing assistant
Then;
Still in general management setting
Select manage language and keyboard
Select Samsung keyboard settings
Select suggest text and corrections
Select manage apps
Turn off all apps in which the page jumps whilst editing or deleting text
Good luck
