You might try OpenBoard - its superior to the built-in Graphene keyboard. I still have an issue with editing text and I'm not sure if that's Amethyst or the keyboard. For some reason hitting backspace removes spacing in messages.

Only complaint with the device itself is that once in a while it's hard to reach all the way across the phone when doing things one handed 😅
OS is great, but for security reasons it's important to stick with the stock keyboard. Emoji selection is weak & autocorrect is buggy & unusable IMO. Not a problem in Telegram and many apps or websites that have their own emojis & spellcheck. Would love for Amethyst to add a basic spellcheck nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z

Once I turned off the double space period feature & all of the autocorrect stuff, that problem went away.
