I got some sort of virus where it asked me if I wanted a new theme. I clicked NO and went to sleep. The next day my keyboard for messages was older than %$#¤*♤☆ old school! It was abc in a □ then def in a □, you get the point. I went through everything on keyboards 100+ times, so did friends. Nothing.
Try changing your keyboard back. Sweep your phone for malware. In the future, if you get a suspicious pop up on your screen, do not click it, just use your home key to back out of it and then run a scan on your phone. Clicking mystery pop-ups will always result in malware.

Firstly initiate a comprehensive scan utilizing either the integrated Device Care feature or a reputable antivirus application. Clearing the cache is also recommended. Employing a trusted antivirus program is the most effective method for malware removal, as these applications are designed to identify and eliminate malicious software from your system.
While manual scans can be attempted to identify potential threats, it is important to acknowledge that sophisticated malware can replicate within the system, masquerade as legitimate processes, and evade detection by the operating system.
1. Go to Settings.
2. Tap Battery and Device Care.
3. Tap Device protection.
4. Tap Scan phone.
5. All of the apps and data on your device will be scanned.
6. Once the scan is completed you will be shown whether or not your device is secure.
Upon malware detection, it is recommended to uninstall any suspicious applications and clear your browser cache.
Should the issue continue, booting into Safe Mode to remove problematic applications may be necessary.
As a final measure, a factory reset should be considered.
