The former green button version will allow alternate suggestions when something is typed incorrectly. Blue Button does not. This new version will also leave the phone screen lit until you cancel it out which kills your battery. When this new version came out earlier this year I thought it would just be a matter of time before they worked out the bugs but it's still the same lousy version. The only temporary fix that I know of is to go into the Google app every single day and uninstall the updates. Are there any other suggestions or maybe a possible permanent fix coming?
Also I had some hope when I saw Google Voice Legacy inside the keyboard settings on One Ui 4. But alas, it seems to be the exact same thing as regular Google voice
