[Samsung Epic 4G Touch] easyrider77:
Yeah I'm on it now...again. I had some weird 3g wonky issues though last time I used it.

I port cars all over town so I'm like all over the place locally, which results in I'd imagine, a lot of tower hopping.

The symptom is, I leave the phone off for awhile, screen off (sleeping) and am doing stuff then a few hours later I a turn it back on to test data, and gps. GPS seemed to work fine and fast, but the 3g, the first time I caught this was when I was checking mail with K9 email, so when it was checking mail it seemed to be really fast, so I thought hrmm, ok lets check data, opened up the stock browser and let it load google.com, and to my surprise it failed, saying the normal "check your data" message it gives.

I looked up at the top and saw it said 3g was active, and had the 3g icon so I was puzzled and used another browser to check thins, and it to gave an errors about the same data. So I was curious, and toggled off and back on data, and then re-checked it and it worked fine this time.

I checked this throughout the day, and the same thing happened, I replicated (as good as I could) each time, letting it sit between times I was delivering a vehicle and each time it seemed to lose the 3g data, even though it still said it had it and the icon was there. This happened all day, in an 8-9 hour day....and I could replicate it exactly the same each time all day long. Everything else was fine and I was on cloud nine before I found the 3g data issue I had stumbled across.

With my basically un-limited knowledge of programming and such, I'm making an educated guess from the wifi/data swap that this is a similar issue, only it involves with the tower hopping, so when it goes to another tower it doesn't adjust or hit the tower right, and then goes into a stall or something, and results in the 3g icon staying there, but the data isn't connected to the tower at all, kinda in a limbo state of sorts and that's why toggling the 3g data off then on again it works fine because it reconnects to the closest tower. Of coarse this is just a guess on my part, but it would make sense. I mentioned this on the 4.4 vilumiatti thread, but got no mention of any fixes or anything. Perhaps I'm the only one with this issue, dunno, I just know what happens and how it happened. Perhaps I could test some things out concerning this and come up with a fix of some sort.

It could have been the modem I was using, as I was using Fl27 at the time, so I am re-testing things with nothing else install except an another browser and my EQ app....other than that it will be stock, with my normal settings in the menu IE: turn off this sound or that sound, enable this or that sound, brightness, etc..etc... which shouldn't affect 3g data at all.

Don't get me wrong I'm not "trying" to find issues with these roms, just I prefer certain things to work, which are GPS (lock-on), Camera (without locking up), Volume (not being at a utterly low level even though the volume is cracked full), and 3g data to work correctly.

I really do appreciate the dev's efforts in fixing things and the fixes they do accomplish, as I'm not a dev or a programmer of any sorts, so I can appreciate the hard work they go through, but for my end I have to expect some things to just work, and if they don't well, I don't have ta sue the rom, simple as that, no harm no foul, so if the 3g works with the modem I'm on, then it was a modem issue, if it still has the same issue, then it has to be in the rom itself.

I tried out carbon rom again to see if I could get the volume to work, and it was a no-go, so I'll try this rom again. I'm on the 4.4.1 right now, so we'll see. Everything else is utterly smooth and sweet, gps lock-on is really nice, volumes are really nice, camera works good, everything except for the 3g issue. I'm crossing my fingers it all works, and it was only a modem issue, so we'll see how it goes.
