I love foxhound roms.i don't ger why everyone is having issues.
1 Wifi issues then flash different kernel like adams
2 Alot of issues such as battery drain has alot to do with kernels or apps running in the back ground, stop the nasty ones and check the battery usage to see what is killing the battery, remove the nasty apps and try a similar app that doesn't hang and drain your battery.
3 battery icon in the status bar can be activated in nova, display settings or if you customize your battery in the foxhound settings, try this first.
4 bluetooth, lte, wifi fixes, just reflash the rom or different kernels or all the above.
5 make sure you always make a backup of your device, one backup that works completely or as long as your connectivity works then don't ever delete that backup, make another backup of your efs folder in your system, you can backup your efs folder if you are rooted and using a root explorer, back it up to your external sd and on another device,
6 if your efs files get corrupted you will practical be bricking your phone. You will lose wifi, bluetooth, ime number, gps, lte 4g 3g all communication. The only way to fix it is to change the Samsung main board for a new one or reinstall your working backup but in some cases it won't fix it, so you will need to restore your efs folder and reboot and everything is back to normal, just make sure you double check all efs folders and files are backed up properly.
Sorry this was rushed and probably worded bad but I hope it helps and makes you all alert.
Thanks raffaele88 for another epic rom.
