A question about how a ROM affects data - Fascinate Q&A, Help & Troubleshooting

Okay, so I've been reading about the issues people are having with "comm rom" and "Evil Fascinate" and how they're affecting data somehow. I don't understand it. I thought the radio handled the data part. Is there a part of the rom that deals with the data itself? Can someone give me some insight on this? I've looked through the files, but can't find anything. I'm not having any problems at all with either if these roms, not with data at all, I'm just trying to figure out why people are blaming the roms. Thanks in advanced.

The roms don't affect data much, if at all. Radio hardware, radio firmware, weather, cell signal, cell tower, geography, topography, man made structures, population density, and solar activity on the other hand can and will affect data.

Don't forget all the people who were having troubles with the network at exactly the same time recently, which seemed to be more of a coincidence than a problem with the rom itself.

Yeah, this is essentially a correlation does not imply causation scenario.

It's an ICS thing. The new update messed with our signal. The only way to fix it is to S-Off and go back to Gingerbread.

Sorry for the late reply, you can search for modems I can provide a link if necessary but a Google search should be fine and you will need to root and have cwm installed to do this or use a flash tool or Odin if you have a galaxy,

I use to get full five bars at home using GB, after updated to ICS (SuperSayain rom) I pretty much only getting 3 bars. What I did was in the mobile network setting, changed mode from auto to WCDMA only and so far i've been getting pretty much 5 bar most of the time with occasionally dropped down to 4. hope this works for you too.
I am also having this strange issue. So is reverting to GB the only way or can you just flash the gb radio? Anybody know anymore about this??
Same issue here. At home used to get full 5 bars, now 3 sometimes 4, which is fine as I am usually on WiFi anyway. Problem is I had great signal all throughout my daily commute to work to where there is sections of my drive that I have no signal. Before in that area it would revert to EDGE from 4G and mine is set to auto.
Just believe like everyone else mentioned that it is the ICS radio. Hopefully an update will fix it

No. And to the people talking about modems and odin and.. yea, no. We don't have modems to flash, and odin is just for samsung devices. Until now we couldn't flash a radio if we WANTED to.
You know the iPhone's fix when people were talking about how bad the signal was for the iPhone4? They had been boosting the REPORTED signal strength. So did HTC, so did Samsung, so did.. all of them. You'd drop a call when it showed you had GOOD signal.
Not a single person has posted about having ACTUAL worse issues. The OP said he can make calls and talks about how many bars.
Apple's opinion:
We have discovered the cause of this dramatic drop in bars, and it is both simple and surprising.
Upon investigation, we were stunned to find that the formula we use to calculate how many bars of signal strength to display is totally wrong. Our formula, in many instances, mistakenly displays 2 more bars than it should for a given signal strength. For example, we sometimes display 4 bars when we should be displaying as few as 2 bars.

People here are having the OPPOSITE problem, it LOOKS like you should have an issue, and you don't.. but people keep posting about it even tho there hasn't been any issues.
This is the ONLY person who had actual signal issues(Weird Interference/Reception Call Issues on my Amaze) I have seen since ICS dropped, and it turned out to be a hair on the contact for the antennae. Read his thread, he methodically checked quality and could answer basic questions - and then he fixed the actual problem.
Edit: I'm not trying to be a jerk, but if someone is ACTUALLY having problems, they actually can't make calls, drop calls where they didn't before, etc.. then there is probably a problem that can be fixed. But unless you are having those issues it is likely that the signal strength you're seeing is more accurate(EXACTLY like the apple quote I put above), they are just doing a better job of SHOWING the actual signal. Which is good, no unexpected dropped calls or BS.

Don't know if that's the case because when I so connect its fast. Just as fast as the first day of the month. I do have the 5gb plan and have never hit it. Been close but never hit it. I'm going to call just in case. You do have a good point.
Do a speedtest. If its 60 kb/s and steady, or something similar, that's your issue

Prioritizing My Data Connection

I recently read an article that stated something like "the president will never miss a call because his phone is prioritized over all the others on AT&T's network". It made me wonder if there was any way for us to trick the towers into prioritizing our phones? While I'm at work I have a horrible data connection because there are so many people around me pulling off the same tower, so I'm trying to figure out some way to get better speeds I'm fairly certain this is all controlled on the carriers side, but I figured I would ask.

No issues. Radio solid fast 3g insanely fast GPS locks. Buy it

This is one of those threads that is meaningless information or worse because the mods combined the forums and the posters failed to flag their carrier. So-called "signal" issues are carrier-specific.
On my sprint s3 I don't have the "los" bug but signal on this phone sucks. Anyone who tells u different is lying. This may be one of the weakest radios on any phone. My photon would have, 4 bars on sprints network where this one will be roaming
Hopefully a radio update will fix these issues

This fits the pattern of other anecdotal reports by some users of Sprint LTE-capable phones, not just the GS3, in some areas.
Since the whole Sprint network is being rebuilt right now on a localized basis, my bet is that these symptoms have something to do with how the new LTE phones interact with the legacy network, or at least with certain regional segments of the network that are under construction right now. Whatever is going on, Sprint is not being forthcoming about the issue.
However, this is a Sprint-specific problem, having nothing to do with the original post, which apparently does not involve Sprint.

Actually I do know how to do a prl and profile update. That doesn't fix a bad radio. The radio on this phone sucks plain and simple.

I'm just going to assume u have never owned a photon because that's what I came from. This phones radio compared to the photon sucks horribly. I roam at the sprint store. Reps there said they are hoping it's due to the network upgrades

No it's due to Motorola holding several patents that allow the cdma radio to be better in their phone.....no other cdma phone will get as good of coverage....HTC LG doesn't matter Motorola is the best coverage of any phone cdma wise but their phone sucks other than that....
Most people forget Motorola was a radio company before they made phones

LFB network bug

I've recently noticed a weird network bug on LFB. If the phone loses signal (on subway etc.) with data on, when signal is available it acts as though the SIM was refused by the network continuing to display Emergency calls only. If I turn data on and off it gets weirder (see screenshot).
The only way to fix it is too reset the radio, with flight mode, or *#*#4636#*#*
It's definitely not a hardware fault since, as you can see it still can connect to the network. It just acts as though the connection was refused (or alternatively does something weird that causes it to ACTUALLY be refused)
Anyone else experienced this??
The phone is an original BTU using unmodified LFB on China Unicom

Are you able to set/receive calls or send/receive SMS? What about USSD codes to your provider?
I've already read about other users complaining about this issue, I guess it's a software-bug in the display.
No. I'm not sure if HSDPA will work in the example pictured. I was in a hurry to make a phone call so just quickly snapped the screenshot then reset the modem.
Messages will get service unavailable. Incoming ones don't get received until I reset

Well 2G is okay. But it sometimes will lose it briefly in the transition from 2g to 3g.
Only Beijing subway line 4 has China unicom WCDMA coverage. the others are limited to 2g at best (except the overground lines, but even they are patchy)

Having updated to the stock LFB ROM and modem (UK, unlocked, unrooted), I'm really perplexed about the behavior of the phone data reception:
(a) 2 weeks ago, I tried using data connection in a friend's flat in Balham (London), could not get ANY data connection all weekend.
(b) Last weekend, data was consistently perfect and fast anywhere in the same flat, all "H+" 8Mbit and lovely.
(c) This weekend, same place but NO reception again, not a saussage. Voice phone worked fine, just no data at all.
And, yes, I've seen "emergency calls only" sometimes even when there is apparently a strong signal.
Back home again (Portsmouth), phone works fine.
On the plus side, battery consumption is wonderfully low!
Can anyone explain what's going on? It feels like the data connection is sometimes reluctant to "log in" or whatever is does! It seems to have a mind of it's own.
Thanks!
You may want to try another modem like DXLF3. It has better data network stability especially in cities or areas with faint signal.
I am planning to upgrade to the LFB, but i am not rooted. Want to be sure if i have problems with the modem signal, do i have to be rooted to install the new modem driver??
Thanks in advance...

GPS Only Work while Moving in car

Throughout the past few months, I have been unable to have a GPS lock or estimate whenever I'm either inside a building or standing still on broad daylight. The only way to get a fix is if I'm driving. I've had this problem on several different ROMs. I've mainly stuck with AOKP, but have tried different modems with the same result. I've also wiped data/cache and SD card several times but to no avail. Others haven't reported this problem so I know it's specific to my phone. For example, if I use Google Now on JellyBean and search for weather, it defaults to Atlanta if I'm not driving around (I live in Puerto Rico)
Now that Jelly Bean is here with Google Now and other apps are constantly taking advantage of your location, I would love to be able to have my GPS fix or give an estimate of my location whenever I'm inside a building or standing still on the street.
Any suggestions?
I'm having the same problem man I turn my GPS on and it won't pin point my location if im driving and turn GPS on it will start to work within maybe a few minutes or so I'm on stock ics rooted with siyah kernel is there any fix maybe for my stock phone its 4.0.3

I had trouble with GPS after flashing CM9 RC2. Have you installed GPS Toolbox? It gives you a bit more information to troubleshoot with.

I'd see eight satellites but would not get a fix. Eventually I reflashed new nightly *and* modem UCLE5 and trouble disappeared.
Have you tried leaving maps or another app requiring location data on for a few minutes (12 1/2 minutes max)? If you eventually acquire a fix then that would point toward your phone not being able to download GPS Assistance data from cell provider. If the phone cannot get AGPS data from cell provider then it has to recieve GPS almanac from satellites at an ungodly slow rate.

That's REALLY weird.
Not locking inside - that's completely expected
Not locking outside - That's not a good sign, but it makes no sense when combined with
Locking in a moving car - My experience is that every GPS I have ever used has significantly more trouble locking when moving then when stationary
Edit: When you say "standing still in the street" - is it a city with tall buildings, or ???
No tall buildings.
The GPS.conf file posted two posts above helps but doesn't solve it completely.
