Random Data Drops

[o2bnclemson]

I don't know if this is a GS4 thing or a TMO thing, but every now and then - no rhyme or reason - my data just drops. The 4G is still "on" but the arrows aren't lighting up and there is no connection. Sometimes it will restore itself after a minute or two, sometimes longer. Sometimes it will bounce all the way down to no data, then back up to 4G. Anybody else run in to this? Very frustrating.

I've Had The Same Problem But Recently While Using The WiFi Tether App My T-Mobile S4 Got Really Hot & All Signal Just Went Away.... I've Tried Restoring But There's Still No Available Signal At All..... Did I Damage Something Internally? Any Help Would Be Great Before Going Out To Purchase A New MotherBoard, Thanks....
