I have been using the Tab S4. A big downside for me is that it will not spell check when the Samsung physical keyboard is being used.
Can anyone tell me if the Tab S7 spell checks when used with the physical keyboard?
Yup, I'm using one of those as well. Nice devices, apart from the spell checker.
In my email client with a physical keyboard I keep an eye on the spelling suggestions bar at the bottom. It's inconvenient, but it works.
I opted to use a cloud service where writing online offers me spell checking with red underlines. I believe Google Cloud and Microsoft's online services both offer this.
Lastly do a web search for turning the spell checker on on your device. Make sure your language is switched to on.
I have found no better methods.
This is an ongoing issue with Android it seems.
