The Xfinity system requires the use of the OK button when changing the channels. Try selecting the Remote Icon on your Android phone, use the Keypad to enter the channel number, then with great speed and determination select the OK button on the D-pad. It may take a couple of tries to get used to selecting all those options with the proper speed, but I have found that this usually works.
I finally solved this issue. If you haven't figured this out yet, re-download the program for your PC and reinstall. When asked to search for your cable box, look for Comcast X1 and use that instead of whatever you are using. This gave me an updated remote control and now when I key in a channel and hit enter, it changes to that channel. Fantastic!
My Mom bought a Slingbox 500 and everything is hooked up fine. The problem is the Android App. It's glitchy. Today the screen size suddenly is half the size it's supposed to be. At one point, the Roku connection completely disappeared from the app. On and on. The Andord App won't sling. Period. Calls to Slingbox reps for assistence are are frustrating and useless. There are two Android phones in our family and the same problems occur on the Android App. My brother has an iPhone and it works fine. It makes the $300 investment on the new Slingbox 500 a waste of money. We've used Slingbox for ten years. The Android App needs IMMEDIATE REPAIRS. Help!!
I recently upgraded (?) to X1 at my house. I have reconfigured the Slingbox through the website to work with the new Motorola cable box. I can control the cable box through the Slingplayer on my laptop. However, I cannot control the Slingbox through my Android Slingplayer app. I can watch TV on my phone but cannot pause or change channels. The phone app goes into "wait" mode as it attempts to execute the change but no change occurs. I have verified that the cable box will change channels with the cable remote control and it also works through the PC version of Slingplayer. My phone is running Android version 4.4.4.
I have tried deleting and reinstalling the Slingplayer app on my phone and relinking the app to my Slingbox account but the problem persists. Any ideas/workarounds?
