My SPH-D710 kept hounding me about some stupid update. Finally on the 100th nag, I gave in and updated. When it restarted, it told me that the firmware was updated to improve connections. Now my phone keeps going into 4G on it's own. I turn off 4G and it turns itself back on. When I turn it off I am left with no connection until Enter and exit airplane mode. My wifi sucks now too. Anyone else having this problem and if so, does anyone have a fix??
