Hi there & welcome :-).
You say that you're having problems with the stock Samsung keyboard.
Have you tried "Swiftkey" which is available in the Play store?
It's a great keyboard for swiping...probably the best. (Plus you can change up the look of it with different themes too).
My name is JJ! I've been working for Samsung for about a year now as part of the Social Media/Digital Team. I love to read, cook and sleep (mostly sleep).
My interests are photography, art and technology.

So many people not happy with S10 Battery Drain also being told to turn stuff off to get more power.
The treads on here have been growing to over 100 pages in some topics all about Battery Drain.
I decided to move it to social media.
I would appreciate a private message from you to advise me what youre guys are doing about it.
