[Android Central Question]

I just recently updated to Oreo. It has changed the way that apps are laid out in folders. The icons are now 4 across where previously it was 3 across. I am constantly hitting the wrong icons as a result. I have a degenerative eye disease and some days can't see. Is there any way to either make the app icons bigger or the folders only have 3 icons across not 4. I have a Samsung S7 and use the stock launcher as it works for me.
