I have a Samsung S8 smart phone Model SM-G950F running Android 9. Sometimes it expands the screen information to a very large size so that not all of it is displayed. It didn't use to do this. Maybe a Samsung software update has caused this. Any ideas what is going on? How do I stop this happening? I am planning to upgrade my phone sometime but I would like to get this phone so it doesn't do this.
I can with text messages expand the screen by using two fingers and expanding. This is nothing like that. Happens particularly on the calculator but on others as well. Suddenly the format is so large it expands so that the screen cannot contain much of it. Can't seem to reduce it except press the on/off select physical button and re-renter PIN. I have looked at the the controls under Apps System etc. In case there is setting - can't see anything. This is not me asking for magnification it just does it. Not sure why. I am entering data in the calculator and all of a sudden it goes into to mega display mode. Looks like a bug to me.
