Thanks! Just go to settings >display >edge screen. There you can toggle it on or off. Not really sure how to add an app to it though as I never use it. I've been with BlackBerry since the side wheel one, the 77 something, can't remember. Then the curves, bolds, storms then onto the Z10 and Z30. After those models I really didn't want to go back to a keyboard, even though they looked pretty good. And after the PRIV, forget it. I needed that large awesome screen! So, I finally went for the S10 + and it's been a great phone for me. The only thing I hate is almost every day there's app updates. And when you first start using it, you need an app for everything, period. Watch a video, you need a video player. Import an alarm or notification sound? You need a music player. Open a document? Yep, you need a reader. The only thing nice about that is that you're not stuck with just one built into the Os. It can be frustrating, but as Crackberry is, this site is full of very knowledgeable people. Have fun with the new phone! Oh, the BlackBerry apps work great on it!
