I have Android 7.1.1. Last update is recorded in the phone info as Aug 31. But suddenly (Sept 22) many things changed in my text messaging. There are now "suggestions" for a reply (in one case an offensive emoji, so random) – no way I can see to remove this new feature. The emojis suddenly changed — bigger and to my taste very unattractive. Changed retroactively too, lol — in old texts. Appearance of text message box changed, as if a new program – now there’s a camera icon to the left, a mic icon instead of "send" etc. What happened?
