I have the S9 and my hubby has the A9. Recently we both have started to have an issue with the phones. Upon swiping open the phone to use, a random web page will open automatically. Is anybody else having this issue and if so do you know how to stop it? Thinking it may have happened from a recent update but not 100% sure.
It'll be an app you maybe installed, usually is. Problem is finding which one, the website might give a clue.
Once you have the phone open you could also try the recent apps tab and see what's on top. Try uninstalling it and see if that stops it.
