I have both the (expensive) paid app and now I'm trying the free app. For many, many, many months, and lately it's gotten much worse, the app will play for only a short time and then it stops and I have to reconnect. I'm currently using the app on a Samsung S2 tablet and a Samsung S5 phone, but I had the same problem on my old Samsung Galaxy Note 10.1. I get messages on my new Samsung S2 that the sling app is slowing down my tablet and should be uninstalled. I frequently get the message that the app has stopped and do I want to wait or stop the app. I have to stop it and restart it. This is extremely frustrating to the max, rendering the app (and thus the slingbox) essentially unusable.
