Random lock screen

[GillM]

I bought a new s24fe this week. I've found that sometimes when I open the phone the chrome lock screen appears before I have a chance to do anything. When I tap in my code it disappears. It also randomly appears when I'm looking at other apps. I've cleared the cache and when I do a restart it doesn't do it for a while but then it starts again for no reason. Can anyone help please?

Hi there 👋 and welcome.
Could you provide screenshot of random lock screen by any chance?

[GillM]

I tried but a note appeared saying that the app doesn't allow screenshots.

Actually, I've realised that it's Google not chrome.

Can you describe more about random Google lock screen does it appear when you try to unlock you phone and dissappear when you type your pin or its like Google search looking thing? As without screenshot it's hard to tell if it's an app causing it or its setting you need to change

OK, I unlock my phone and the Google lock screen then appears, so I can't tap on any of my app icons until I unlock Google then Google doesn't actually open, it just disappears and I'm able to see my app icons. I'm sorry but I don't know how to attach a photo to this site.
