Recently my Tab S8+ was producing multiple keystrokes from using my phycial keyboard. Eg, I press the letter "r" and on screen "rrr" would appear. This would happen for all keys, including space, etc.
I went to Samsung and thought it was the Keyboard as the problem - unforunately I was unable to buy a new keyboard for my Tab S8+.
Picked up the new Tab s10+ today - fantastic - however not long after using the Tablet, unbelievably, the same issue arose. Called Samsung Support.
We worked through various trouble shooting to no avail. Whilst on hold, I saw some similar postings online with people resetting the "Accessibility" function in settings.
Whilst in Accessibility settings, I saw that my NetGear Armour was listed and running. I stopped it from running and problem now fixed! - thanks to Samsung Support for attempting to fix the issue but seems it was a software clash between NetGear and the operating system.
So if it's only doing it when you use the keyboard then most likely sadly it is definitely the keyboard. To be fair I actually had a lot of problems with many Bluetooth keyboards they're very sensitive and the way that I would fix this is at least this was years ago I would just tap whatever letter or space really like I'm talking fast like a super quick tiny light pick but that became pointless to me because it didn't feel like a keyboard so I quit using them. Now if you can find a keyboard that might plug in directly to the tablet via the USBC port think like how keyboards plug into a computer you may not have this problem. The reason why I say you may not have this problem is because I've never tested this theory because when I had this issue I just quit using keyboards all together. I try to stick to the on screen keyboard the one that pops up I just think it's more natural and it works I use a tab S9.
