I've looked all over and not found anything on this. I had 2 HTC phones before my galaxy (incredible and rezound). The HTC email app allowed me to sync a certain number of days of email instead of a number of emails. This worked great for me and my wife as nothing changed as you deleted emails. Now on my S4 if I delete an email an old one pops up as new (unread notice on icon). Is there another android email app like the HTC one that will allow me to sync a number of days not emails? Or does anyone know if I pull the app from my root zip files on my laptop for the rezound if it will work on the S4 -> I figure it needs some sense stuff for widgets to function but the core app may not need sense. Really I just want an email app (preferably free) that has a similar function to the HTC one. Every one I find has the quantity of email option though not a time option.
