Samsung Galaxy S5 Android 4.4.2 This is quite odd. My mobile data (4G LTE) symbol in the header area used to dim (like when you disable mobile) when my Wifi kicked in and it does not anymore. So it always appears that both 4G and Wifi are active at the same time. Only after watching which up/down arrows are flickering do I know which is working. And on some occasions, the arrows on both flicker. I am not 100% sure, but I think this started after I turned on the Ultra Power Savings mode. Can anything be done to resolve this? *** Resolved *** Disabled Verizon's Caller Name ID app.
