Yeah from memory it was the default for Samsung, but stock Android had it the other way around. I’ve always preferred it, much easier to reach with my thumb while holding it in my right hand. I always swap it (custom firmware ensures this) and also have it set so a long press of the back button will force close any foreground app.

If you’ve got a Pixel phone I would look at installing GrapheneOS on it. Even if it’s a work phone, chances are they won’t know. If they find out, say you were ensuring the security of your device, for the benefit of both you and your employer.
