[Samsung Galaxy S 4 Unified Development] Zaileion:
Regarding radio issues:

Basrband is NC6

Model is sph-l720t

Carrier is Sprint

The "t" at the end of the model means sprint spark which is software managed inclusion of the 41 and 25 bandwidth. It significantly increases lte speeds. Sometimes upwards of 12MB/s.

These issues only affect global or lte (recommended) mobile data settings. 3g always works.

I live in NJ amd work in DE and when I drive from home to work somewhere along the line I loose data. To fix the issue I can go into mobile data settings and switch from Global to 3g. 3g works always. Or I can wipe and flash my backup. This option them requires me to reflash the backup again upon ariving home. Or I can wipe and reinstall. I can also force this effect by switching between global, lte and 3g waiting a minute or 2 between each switch it will all the sudden no longer connect to lte.

There is also random data drops. Sometimes a few hours after a flash or sometimes I'll get almost a day.

Bluetooth headset hang up button doesn't work unless I hold it in which activates something else but it forces a hang up. Sometimes I get no audio at all through bluetooth. If I sit my phone down and walk away my head set says in my ear disconnected but when I walk back in range it does not reconnect. I also noticed even though its been disconnected the phone still says its connected. Even if I remove the headset and sit it down and walk back and check the phone it still says connected. If I turn bluetooth off I can't turn it back on without reboothing. The switch joust automatically switches back to off.
