In an attempt to save battery life, I've followed the steps found in the internet to disable 4G LTE and use only 3G. Motorola Droid 4: Disable 4G/LTE When the 4G is disable, however, certain apps that require data connection stop working. For example, weather bug, shazam, etc. Some continue to work, like Gmail. Any idea why this is happening? Has anyone actually been able to disable 4G and still use all their apps?
