Since Android update to 6.0.1, Samsung SM-J500, a few issues

[bornfr3]

I've noticed I can't use predictive textd for Google searches in portrait view only in landscape view which takes longer. I've had to obtain another keyboard specifically to type in my search AND also that my email remains on my mobile phone when it's already downloaded emails from the server to my PC, I've searched for a solution but my settings appear accurate, I've changed nothing since the upgrade. Any suggestions on either of these issues would be appreciated. I've just joined Android Central because of these problems.
