I got the update by manually checking the software updates. I'm mostly happy with it. It sure doesn't change a lot. One problem I'm having is that my bluetooth is completely unreliable since the update. It worked perfect with my headset before and now it will completely disconnect at times and otherwise it is very patchy. Has anyone else noticed this?
The best thing about this update is that it allowed me to install Samsung's Good Lock lockscreen. This adds a bunch of useful shortcuts to the native lockscreen that are very usefull.
What is this good lock screen you speak of? I see nothing new on mine? I seem to have lost Text notifications as well, along the top status bar, can only select popup, or just to show the little envelope.
The lock screen should be in Galaxy Apps but it is officially only compatible with S6 and up. So I installed the APK from apkMirror.
