@Sidjames: Are you using the dedicated Google app? If so, head to the Play Store and check for any available updates that might resolve the issue. If the issue persists, go to Settings > Apps > Google > Storage > Clear Cache, then restart your phone to see if this helps.
define 'google search', is it a browser? a widget? something else?
what keyboard do you use? Samsung keyboard, google keyboard, something else?
and what is the new screen that pops up?
So one one of the screens you can see my settings for the 'Google' app, and there are many, also Google services, anyway, it uses no resources while it's allowed to run in the background. If that is still not your thing, on the other screen I have the search widget by Chrome, it goes straight to the browser if you type anything in there. Of course it is a Google app, so maybe it will behave same as the default Google widget....who knows, but I guess it's an option. To add the chrome search widget, just tap and hold on the chrome icon and there will be an option as 'widgets' . Other than that I would allow Google to run in background 🤔
well, i did not consider the power saving mode, bcoz it's always 'on' on my phones, only for some geo tracking apps i can't be on power saving else it turns off the GPS if on stand by;
i guess you found the solution mostly by yourself, i also will remember the thing with power saving if some problems occur on my side;
on Huawei and Xiaomi phones i can choose the apps, where the selected apps are not on battery saver while the rest is, as seen on the screenshots, but on Samsung it doesn't say that the selected apps will be unaffected by power saving:
dark mode is the solution 😂 seriously, Samsung degraded with the quality of their products so much, that I wonder if the company won't go bankrupt anytime soon.
