I have attached a photo of a issue I found.

It isn't showing green right now but instead when I unlock my device it shows the next page icons and text. 

I've never had this happen before until I got my phone back from Samsung.

Why is it doing this

Every time you unlock screen same page shows

It unlocks to the last page you were on not the home page.

I mean, I'm on my main homescreen page but when I unlock my phone you can see a glimpse of the next page icons and labels. That shouldnt happen.. right

Looks like home page to me

Maybe I didn't word it right.
When I unlock to my homescreen, the 2nd page of the homescreen on the right hand side also shows for a split second the app icons and label.
It's never happened before

You can try cleaning cache on one home in the settings, apps or uninstaling updates this will reset one ui home

Thank you. Before this issue I had my phone show a green flash in the same spot but Samsung repair told me there was no fault.
My phone's been factory reset and I still get this problem.
I'm not sure what else to do
I think I'll have to leave it and see if it gets worse

Id like to add, this doesn't happen often, maybe once every 100-200 unlocks

Sorry I wouldn't know what to do with flashing screen,, have you tried put apps in folders so there is no second page
