I had this problem, It happens when I make a new "Area" and add channels. I can repair the problem if I go to Android settings then apps and erase the DATA from the app. The new area is gone and the app will then work.
Please remember that the A/C charger for this phone is 12-volts output. Almost ALL USB chargers in the US are 5-volts output. 5volts will charge at a very slow rate.
