Are there any android apps or combination of apps that can mimic the exact way sms notifications are handled on ios ..that is a text message preview will appear on the screen and stay on the screen even after the screen times out, so that when you turn your device back on, you will still see the the message ... In the Android system, it seems that you have to go to the lock screen first after a timeout, then go to your home screen, then pull down the notification screen to see incoming sms text. I much prefer the "sticky" screen behavior of the ios, whereby sms messages will remain until you swipe them away, even after screen turn off.
