Ever since the recent update my tables like the tab 7 plus no longer spellcheck with a physical keyboard attached. Likewise a portable keyboard I use for my fold is not working either. As you type a misspelled word no underlining lining. This all started with the new update about a month ago.
The onscreen keyboard works fine. This happens in all online situations for instance office 365 online. The local apps seem to work fine. So it seems to have something to do with webforms. All of it works fine when using the on screen keyboard.
this is a huge issue, ive been complaining for a while now even with old One Ui 4.0 spell check didnt work for all apps, only workaround is to use SwiftKey it will give you predictive bar with physical keyboard. i cannot understand why Samsung cannot just implement same function as SwiftKey. looks like their software team just out of touch.
To turn spell check on or off on Android, you need to go to Settings > System > Language and input > Keyboards > Gboard > Text correction > Spelling > Spell check and flick the toggle into the desired position.
