[Samsung Galaxy S 4 Unified Development] smikwily:
I can understand your feelings on this, but a logcat has never been requested to my knowledge. I've never done one, but I've given it a shot. I've sent you a PM with a link. If the format is wrong or something, let me know what to do and I'll try to adjust accordingly.

I do know that at least one other Sprint user has commented on Plus (Donnie Yandell, Oct 29, 2014) that they are unable to roam either on Sprint.

I woke up randomly at 4AM, as my brain sometimes does and the status of my phone is this: my wifi is on/connected and my BT is on/disconnected. I ran to get pizza for dinner for the fam. I've been making my way through a podcast, and since the pizza place is only about 10 minutes away, I knew I wouldn't make it very far. I enabled BT on the way out the door and listened to the podcast on the way. When I got out of the car, my BT disconnected, as my in-car BT device is powered by the car's power and it turns off when I turn the car off. I got the pizza, then tried to listen to the podcast when I got back in the car about 20 later. If memory serves, BT was on, but I couldn't get audio from the phone over BT. I attempted to turn off the BT (as that sometimes helps), but the BT wouldn't turn off. It acts as if it is going to, but it the power button flicks from on, to grayed out, says it is shutting down, then turns back to greyed out (on, but not connected). I think I rebooted at that time (possibly after turning airplane mode on, then off). Currently, my BT is on, but disconnected. If I try to turn it off it says it is "Turning Bluetooth off...", but flips back to on and disconnected after about 10 seconds. I turned my wifi off and cellular is showing two bars, but no data. I gave it a few moments and refreshed the browser and it did connected to LTE with two bars. Sometimes I have to do the same hoop jumping to get cellular data to return.

As I stated, the connections in general seem flaky. It may be my device, I could be doing something incorrectly, etc. I will admit that. I do not blame your ROM specifically, but I've sort of stuck with it for a while longer than I have others because A) I like it and B) you've offered quite a lot of support via Plus, which I do greatly appreciate. It acts as if the radios are fine, but if I change towers, the wifi disconnects due to sleep, the BT disconnects because of the receiver losing power and turning back on, etc. , then I usually try to turn off the given radio. If that doesn't work, I change to airplane mode. If that doesn't work, I try a reboot. I'll even power off and battery pull depending on the situation. Sometimes it even requires a little more fiddling than that.

Per your previous request (and since I knew I needed to do it at some point), I went back to stock and made sure my radio/firmware was at the latest. I believe that is the case. The zip I flashed the ROM from is DU_jflte_4.4.4_20141025-0025.v8.1-OFFICIAL.zip with my GAPPS package being pa_gapps-stock-4.4.4-20140923-signed.zip. It has been a short while, but I believe I did a clean/full flash. I'm a father of two and my brain can be mush, so I can't gurantee, but I believe I have done so if a dirty flash has had issues.

I've been flashing ROMS since my HTC Hero on Sprint, but I'm far from an expert. Again - sorry for sounding like a broken record. It isn't a ton, but I threw a small donation your way to let you know that your feedback and suggestions have been appreciated, along with your work on this ROM. If you have any other suggestions, let me know. If you prefer I pack up and move on, I will do so.

Edit: forgot to mention - I commute via interstate for about 50 miles each way. I do notice cellular sometimes drops when (I assume) I jump from tower to tower. I have noticed this with some other ROMs in the past, so that isn't specific to DU. Unsure if that is a known with the base for the ROM, etc.

tl;dr - I could be an idiot, but I thank you for your help. Radios are all over and that includes wifi, cellular, and BT. Things are usually fine on initial connection, but when trying to reconnect or turn off, things don't work quite right. When trying to reconnect, sometimes I can't turn a connection off, which usually requires airplane mode, reboot, or hard down to fix.
